Duplicating pages

Select a page in the Pages pane, then use one of the following methods to insert the duplicate page after the selected page:

Renaming pages

When pages are inserted into a drawing, they are automatically named as Page 1, Page 2, and so on in the Pages pane, the Navigator dialog, or the Navigator deck in the Sidebar. As the page order is changed, pages are automatically renumbered making it difficult to identify the pages. To solve the problem of identifying pages, it is recommended to give each page a memorable name.

1)  Select a page for renaming in the Pages pane.

2)  Use one of the following methods and rename the selected page:

3)  In the Rename Page dialog that opens, type a new name for the page and click OK.

Master pages

A master page is a page used as a starting point for all pages in a drawing controlling the basic formatting of all pages based on the master page. It is similar to a page style in Writer, or master slide in Impress. A drawing with multiple pages can have more than one master page allowing a different look assigned to separate pages in a drawing, for example title page, contents page, and drawing pages.

A master page has a defined set of characteristics. For example, background objects (such as logos, decorative lines), text formatting, blocks of standard text, and fields such as page numbering, date, and filename.

Master page view

Go to View > Master on the Menu bar and open the master page view. This also opens the Master View toolbar (Figure 5). If this toolbar does not open, go to View > Toolbars > Master View on the Menu bar.

To return to normal page mode, click on Close Master View in the Master View toolbar, or go to View > Normal on the Menu bar.

Creating master pages

Each drawing created uses the default master page. When a drawing has multiple pages, master pages are created and added to the drawing as follows:

1)  Go to View > Master on the Menu bar to open the master page view and the Master View toolbar.

2)  Create a new master page using one of the following methods. After creation, the new master page is automatically selected.

3)  Add the required graphic objects, logos, fields, text and so on to the selected master page, then save the drawing.

4)  Assign the new master page to a drawing page. See “Changing master pages” on page 1 for more information.

5)  If necessary, rename the master page with a meaningful name, see “Renaming master pages” on page 1.

Renaming master pages

Each new master page created has the default name of Default 1, Default 2, and so on. It is recommended to rename a new master page with a more meaningful name. The default master page that was created when the drawing was created can also be renamed.

1)  Go to View > Master on the Menu bar to open the master page view and the Master View toolbar.

2)  Use one of the following methods and open the Rename Master Slide dialog:

3)  Enter a meaningful name for the master page in the Name text box in the Rename Master dialog.

4)  Click OK to save the changes and close the Rename Master Slide dialog.

Changing master pages

When a drawing uses several master pages, each page in the drawing can use a different master page.

1)  Go to View > Normal on the Menu bar.

2)  In the Pages pane, select the page where the master page is going to be changed.

3)  Right-click on the page in the Workspace and select Change Slide Master from the context menu to open the Available Master Slides dialog (Figure 6).

4)  In the Select a Slide Design preview box, select a master page design for the selected page.

Figure 6: Available Master Slides dialog

Figure 6: Available Master Slides dialog

5)  If necessary, select Exchange background page to use the selected master page for all pages in the drawing.

6)  If necessary, select Delete unused backgrounds to delete any master pages shown in Select a Slide Design preview box that have not been assigned to a page.

7)  Click OK to change the selected master page and close the Available Master Slides dialog.

Deleting master pages

Deleting master pages is only available when there is more than one master page in a drawing.

1)  Go to View > Master on the Menu bar to open the master page view and the Master View toolbar.

2)  Use one of the following methods to delete a master page. The deletion of the master page is immediate and there is no confirmation

Note

The default master page created when the drawing was first created cannot be deleted. Also, if the drawing only uses one named master page, then that named master page cannot be deleted.

Master pages from templates

Master pages from templates available in LibreOffice can be used for a drawing. If the master pages from a template use a different page size, the master pages loaded into a drawing are adapted to the page size used in the drawing. This may cause some objects to be stretched, or incorrectly positioned when adapted to fit the drawing page size.

1)  Go to View > Master on the Menu bar to open the master page view and the Master View toolbar.

2)  Right-click on a master page displayed in the drawing and select Change Master Slide from the context menu to open the Available Master Slides dialog (Figure 6 above).

3)  Click on Load… to open the Load Master Slide dialog (Figure 7).

4)  Chose a template category from the list displayed in Categories.

5)  Choose a template from the list displayed in Templates.

6)  If necessary, click on Preview to display a preview of the selected template.

7)  Click OK to close the Load Master Slide dialog. The Available Master Slides dialog opens displaying the selected template in Select a Slide Design.

8)  Select the master page required in Select a Slide Design.

9)  If necessary, select Exchange background page to use the selected master page for all pages in the drawing.

10)  If necessary, select Delete unused backgrounds to delete any master pages shown in Select a Slide Design that have not been assigned to a page.

5)  Click in a blank area of the master page to deselect the field.

Note

The options available in the Edit Field dialog and context menu change to match the field type that has been selected for editing.

Templates

A drawing template is used as the starting point for all new drawings. For example, a template can include a company logo, name and information on the first page of a drawing with the remaining pages in a drawing only showing the company logo and name. Templates can contain anything that regular drawings can contain, such as text, graphics, a set of styles, and so on.

All document types created using LibreOffice are based on templates. If a template is not specified when a new document is started, then the default template for that type of document is used. This default template uses a set of properties that are hard coded into LibreOffice. If necessary, the default template for drawings that is hard coded in LibreOffice can be changed, see “Default template” on page 1 for more information.

For more information on templates and obtaining templates from other sources, see the Getting Started Guide.

Draw does not have any predefined templates when it is installed on a computer. However, templates can be created using methods described in the following sections. Templates can be installed that have been obtained from other sources, see "Importing templates" on page 1 for more information.

Creating templates

Using Save As Template dialog

1)  Open a drawing to use as a basis for a template, or open and edit a template to use as a basis for a new template.

Multiple layers

Layers in LibreOffice Draw allow assembly of related elements in a drawing. Think of layers as individual workspaces that can be hidden from view, prevented from printing, or locked so that changes cannot be made.

Layers do not determine the stacking order of objects on a drawing, except for the Controls layer, which is always in front of all other layers. The stacking order of objects on a drawing is determined when objects are added. The stacking order of objects can be rearranged by going to Shape > Arrange on the Menu bar.

Layers in a drawing are indicated by tabs located at the bottom of the Workspace and above the Status bar, as shown in Figure 13. By default, the Layout tab is always selected when a drawing is opened. Click on another tab to select another layer in the drawing.

Figure 13: Example of Layers tab in Draw

Figure 13: Example of Layers tab in Draw

Notes

When a new layer is added, the layer is added to all pages in a drawing. However, when an object is added to a layer, the object is only added to the selected drawing page.

If an object is to appear on all drawing pages (for example, a company logo), add the object to the master page by going to View > Master on the Menu bar. See “Master pages” on page 1 for more information.

Default layers

Normal view

In Normal view, LibreOffice Draw provides three default layers that are visible to the user. These default layers cannot be deleted or renamed.

Layout

The default workspace where objects are normally placed.

Controls

Used for form controls that have been assigned an action. Objects on this layer are always in front of objects on other layers. To prevent form controls from being visible on a drawing, deselect the Visible option in the Insert Layer or Modify Layer dialog. To prevent form controls from being printed, deselect the Printable option in the Insert Layer or Modify Layer dialog.

Dimension Lines

When dimension lines are drawn, the dimension lines are automatically placed on this layer. To prevent dimension lines from being visible on a drawing, deselect the Visible option in the Insert Layer or Modify Layer dialog. To prevent dimension lines from being printed, deselect the Printable option in the Insert Layer or Modify Layer dialog.

Master view

In Master view, LibreOffice provides a single layer, Background objects. This layer is used to places objects that appear on every page in a drawing, for example company logo, date, page number, drawing title, and so on.

Inserting layers

1)  Use one of the following methods to open the Insert Layer dialog (Figure 14):

2)  Enter meaningful names for the layer in the Name and Title text boxes.

3)  If necessary, enter a description for the new layer in the Description text box.

4)  Select Visible for the layer to be visible in a drawing. When Visible is not selected, the layer is hidden and its name in the layer tab changes color to blue.

5)  Select Printable for the layer to print when the drawing is printed. The name of a layer is underlined in the layer tab bar when Printable is not selected. For example, not printing a layer is useful if the layer is a draft layer for guides or annotations used in creating the drawing, but this draft layer is not required for the final printed output.

Figure 14: Insert Layer dialog

Figure 14: Insert Layer dialog

6)  Select Locked to prevent any objects on a layer from deletion, editing, or moving. No additional objects can be added to a locked layer. The name of a locked layer is changes to Italic text in the layer tab bar. For example, locking a layer is useful when a base plan is to be protected while adding a new layer with other details.

7)  Click OK to close the Insert Layer dialog and the new layer automatically becomes active.

Modifying layers

1)  Select the layer that is going to be modified.

2)  Use one of the following methods to open the Modify Layer dialog. The Modify Layer dialog is similar to the Insert Layer dialog (Figure 14):

3)  Make the necessary changes to the attributes for the layer.

4)  Click OK to save the changes and close the Modify Layer dialog.

Working with layers

Selecting a layer

Click on the layer name tab in the Layers tab bar to select and activate the layer. Objects added to the drawing are only added to the active layer. Form controls are automatically added to the Controls layer and dimension lines are automatically added to the Dimension Lines layer.

If there are several layers in a drawing, a layer tab may not be visible on the Layers tab bar. Use the navigation icons on the left of the Layers tab bar to navigate to the required layer.

Hiding layers

1)  Select the layer that is going to be hidden and open the Modify Layer dialog. See “Modifying layers” on page 1 for more information.

2)  Deselect Visible and click OK. The text on the layer name tab changes color to blue. Any objects placed on a hidden layer are no longer visible on the other layers of the drawing.

3)  Alternatively, hold down the Shift key and click on the layer name tab to hide the layer.

Showing hidden layers

1)  Select the hidden layer that and open the Modify Layer dialog. See “Modifying layers” on page 1 for more information.

2)  Select Visible and click OK. The text on the layer name tab changes color to the default text color. Any objects placed on a hidden layer are now visible in the other layers of the drawing.

3)  Alternatively, hold down the Shift key and click on the layer name tab to make the layer visible.

Locking layers

1)  Select the layer that is going to be locked and open the Modify Layer dialog. See “Modifying layers” on page 1 for more information.

2)  Select Locked and click OK. The text on the layer name tab is underlined. Locking a layer prevents any modification of the layer.

3)  Alternatively, hold down the Ctrl (macOS ⌘) key and click on the name tab to lock the layer.

Unlocking layers

1)  Select the locked layer and open the Modify Layer dialog. See “Modifying layers” on page 1 for more information.

2)  Deselect Locked and click OK. The text on the layer name tab is no longer underlined.

3)  Alternatively, hold down the Ctrl (macOS ⌘) key and click on the name tab of the locked layer to unlock it.

Renaming layers

1)  Select the layer that is going to be renamed and open the Modify Layer dialog. See “Modifying layers” on page 1 for more information.

2)  Enter a new name in the Name text box and click OK to save the change.

3)  Alternatively, right-click on the name tab of the layer and select Rename Layer from the context menu. The text becomes editable allowing the name to be changed. Click outside the tab area to save the change.

4)  Alternatively, hold down the Alt key (macOS ⌥) and click on the name tab. The text becomes editable allowing the name to be changed. Click outside the tab area to save the change.

Note

Only layers that have been added to a drawing can be renamed or deleted. The default layers Layout, Controls, Dimension Lines and Background objects cannot be renamed or deleted.

Deleting layers

1)  Right-click on the name tab of the layer that is going to be deleted and select Delete Layer from the context menu.

2)  Confirm the deletion of the layer. The layer and all of the objects on the layer are deleted from the drawing.

Moving objects between layers

If objects are selected on a layer, the Status bar indicates how many objects are selected. The position of the moved objects does not change in the drawing and the layer where the objects have been placed is displayed in the Status bar. Move the selected objects from one layer to another layer using one of the following methods:

Dimensioning

Dimensioning objects in Draw and then displaying the dimensions makes drawing look more like an engineering drawing. When dimensions are created, they are automatically placed on the Dimension Lines layer.

Dimensioning objects

1)  Dimension an object using one of the following methods:

2)  Position the cursor at one corner of the object, then click and drag the cursor to draw the dimension line. To restrict drawing the dimension line in the horizontal or vertical direction, press and hold the Shift key while dragging the cursor.

3)  Release the cursor when the end of the dimension line is reached and the dimension line is drawn. The dimension is automatically added (as shown by the example in Figure 17) and the dimension line is also placed automatically on the Dimension Lines layer.

4)  To edit the text of the dimension, double-click on an unselected dimension line to enter text edit mode and make any necessary changes. Click outside the dimension line to save the changes.

5)  To configure the dimension line, see “Configuring dimensioning” on page 1.

Note

After editing the dimension text, entering text and then deleting text, save the drawing and reopen it to enable automatic measurements for dimensioning.

Configuring dimensioning

Drawing object styles

1)  Open the Graphics Styles dialog (Figure 18) using one of the following methods:

Figure 18: Graphic Styles dialog — Dimensioning page

2)  Click on Dimensioning to open the Dimensioning page in the dialog.

3)  Make the changes required to dimensioning using the various options in the Line and Legend sections on the Dimensioning page.

4)  Click OK to save the changes and close the Graphic Styles dialog.

5)  To reset the dimensioning options to the default properties of the template, open the Graphics Style dialog, then click on Standard.

Dimension line dialog

1)  Draw a dimension line. See “Dimensioning objects” on page 1 for more information.

2)  Right-click on the dimension line and select Dimensions from the context menu to open the Dimension line dialog (Figure 19).

3)  Make the required changes for dimensioning using the various options in the Dimension line dialog.

4)  Click OK to save the changes and close the Dimension line dialog.

Dimensioning options

The dimensioning options in the Dimensions page in the Graphics Style dialog and the Dimension Line dialog are as follows. The preview in the dialogs changes as the following options are changed showing how the dimension line appears in a drawing.

Line

Sets distances between the dimension line, guides and the object.

Line distance

Specifies distance between the dimension line and the object or baseline. A minimum of -10mm to a maximum of 10mm can be entered in the text box. The lower the value, the closer the dimension line is to the object or baseline.

Figure 19: Dimension Line dialog

Figure 19: Dimension Line dialog

Guide overhang

Specifies distance the guide extends above or below the dimension line. A minimum of -10mm to a maximum of 10mm can be entered in the text box. Positive values cause the guide overhang to extend above the dimension line. Negative values cause the guide overhang to be below the baseline.

Guide distance

Specifies length of the right and left guides below the dimension line toward the object. A minimum of -10mm to a maximum of 10mm can be entered in the text box. Positive values extend the guides above the baseline and further away from the object. Negative values extend the guides below the baseline and closer to the object.

Left guide

Specifies length of the left guide starting at the dimension line. A minimum of -10mm to a maximum of 10mm can be entered in the text box. Positive values extend the guide below the dimension line toward the object. Negative values move the guide away from the object.

Right guide

Specifies length of the right guide starting at the dimension line. A minimum of -10mm to a maximum of 10mm can be entered in the text box. Positive values extend the guide below the dimension line toward the object. Negative values move the guide away from the object.

Measure below object

Reverses positions and lengths of the dimension line and guides set in Line options.

Decimal places

Specifies number of decimal places used for the display of line properties.

Legend

Sets the properties of the dimension text.

Text position

Determines position of the dimension text to the dimension line and guides. The AutoVertical and AutoHorizontal must be deselected before a text position can be assigned.

AutoVertical

Determines optimal vertical position for the dimension text.

AutoHorizontal

Determines optimal horizontal position for the dimension text.

Parallel to line

Displays, when selected, text parallel to the dimension line or, when deselected, at 90 degrees to the dimension line.

Show measurement units

Shows or hides dimension measurement units. A measurement unit is selected from the drop-down list.

Note

The dimensioning options are linked with the current drawing. Any changes made apply only to the current drawing. New drawings start with the standard properties of Draw. If the dimensioning options are to be used for future drawings, save the drawing as a template.

Tip

When dimensioning objects, it is recommended to use the zoom function, guide lines and snap functions so dimension lines can be accurately placed on an object. See Chapter 3, Working with Objects and Object Points for more information.

Drawing to scale

In Draw, the predefined Workspace drawing area is normally Letter or A4 page size, depending on the computer setup and the default printer connected to the computer. However, depending on the actual size of the drawn objects, it is often convenient to reduce or enlarge the drawing by scaling (for example 1:10 or 2:1).

Note

If drawing to scale, dimension configuration values in the Graphics Style dialog and the Dimension Line dialog are also to scale. For example, a value of 10mm in the dialog results in a dimension value of 300mm if the scale has been set to 1:30.

Specify the drawing scale by going to Tools > Options > LibreOffice Draw > General (macOS LibreOffice > Preferences > LibreOffice Draw > General) to open the Options dialog (Figure 20), then select a value from the Scale drop-down list. The default setting for this option is 1:1. When a change is made to the drawing scale, it is reflected in the rulers at the top and left side of the Workspace.

Figure 20: Options LibreOffice Draw dialog — General page

Figure 20: Options LibreOffice Draw dialog — General page

Figure 21: Example of drawing to scale

Figure 21: Example of drawing to scale

  1. Drawing scale 1:1

  2. Drawing scale 1:4

  3. Drawing scale 4:1

Any change in the drawing scale has no effect on the basic drawing operations. Draw automatically calculates the necessary values (for example, dimension lines). The spacing of the grid points is independent of drawing scale as the grid is only a visual drawing aid and not a drawing element.

An increase in scale (for example 1:4) allows large objects to be drawn that would not fit into the paper size for a drawing. A decrease in drawing scale (for example 4:1) allows small objects to be drawn accurately at an increased size and make them easier to understand. Examples of drawing to scale are shown in Figure 21 where all three rectangles are the same size in the drawing.

Multiple views of a drawing

Several views of the same drawing can be opened and used in LibreOffice Draw. These views are displayed in separate windows and are useful in displaying views of the drawing, for example, master page and normal page open at the same time. However, make sure that the correct view is active when saving a drawing.

To open a new window displaying the same drawing file, go to Window > New Window on the Menu bar. A change to the drawing in one window is immediately reflected in other open windows.

The filename in the title bar for each open window is automatically numbered as shown by the example in Figure 22. If other LibreOffice documents are open at the same time, this windows list includes all the open documents. The active window has a marker by its filename in the list.

Switch between windows by clicking on a name in the list, or by clicking on the window itself if it is visible on the display.

Use one of the following methods to close a window:

Renaming themes

To rename a theme that has been added to Draw, right-click on the theme name and select Rename from the context menu.

Note

Only themes and images that have added to Draw can be renamed. Themes and images included with the LibreOffice installation cannot be renamed.

Colors

Draw (like all LibreOffice components) uses colors grouped into color palettes. Colors can be created to suit drawing requirements. All custom colors created are placed in the custom color palette. The following explains the color models that are used to create a custom color.

Red, Green, Blue (RGB)

The RGB color model is based on the additive color model of light waves and is designed for electronic displays and computers. This means, the more color added, the closer a color moves towards white. RGB is created using scales from 0 to 255. When black is used, the values are R=0, G=0, and B=0. When white is used, the values are R=255, G=255, and B=255. LibreOffice uses the RGB color model internally for printing in all LibreOffice modules.

Cyan, Magenta, Yellow, Key (Black) (CMYK)

It is a subtractive color model where colors are subtracted to change, or create a color. It is mainly used in printing, which is why printer ink cartridges are labeled CMYK. CMYK works on a scale of 0 to 100. When black is used, the values are C=100, M=100, Y=100, and K=100. When white is used, the values are C=0, M=0, Y=0, and K=0.

Hue, Saturation, Brightness (HSB)

HSB values are an alternative representation of the RGB color model and were designed to be more closely aligned with the way human vision perceives color-making attributes. Use HSB values to fine tune any custom colors that are created.

Tip

More information on color models and color values can be found at https://en.wikipedia.org/wiki/Color_model.

Changing colors in objects or lines

When changing colors in objects, color palettes are used to select colors. These color palettes are installed with LibreOffice and are used in all the LibreOffice modules. Using color palettes is similar across all types of objects, but accessing the color palettes does vary according to the type of object selected.

Color Bar

Although LibreOffice includes tools to precisely specify a color, it also includes a Color Bar (Figure 29) for quickly changing color in object area fills, borders, or lines.

1)  Select an object in the drawing.

Figure 27: Color Bar (Color Palette)

Figure 27: Color Bar (Color Palette)

2)  Go to View > Color Bar on the Menu bar to open the Color Bar. When the Color Bar opens, it is labeled Color Palette.

3)  Left click on a color to change the area fill color, or right-click on a color to change the border or line color of a selected object.

4)  Left click on the X box in the bottom left corner of the Color Bar to remove the color from an object fill, or right-click on the X box in the bottom left corner of the Color Bar to remove the color from an object border,

5)  To close the Color Bar, go to View > Color Bar on the Menu bar and deselect Color Bar.

Note

The colors available in the Color Bar are from the Standard color palette that is part of the LibreOffice installation.

Figure 34: Pick a Color dialog

Creating colors

Using Pick a Color dialog

1)  Select an object, or text and open the Pick a Color dialog (Figure 34) using one of the following methods:

2)  Select a color range on the vertical color bar in the Pick a Color dialog that approximately matches the custom color being created.

3)  Click and drag the small target circle in the color box until the color matches the custom color required. The values for RGB, HSB and CMYK change as the small target circle is dragged around the color box helping to create the exact color, if the color values are known.

4)  Alternatively, if the color values, or hex number, are known, enter these values in the appropriate text box. The values in all the text boxes change to match the new values. For example, enter HSB values, the RGB, CMYK and Hex values also change to match.

5)  Click OK to save the changes and close the Pick a Color dialog.

Notes

When using the Line or Character dialog to open the Pick a Color dialog, the custom color created cannot be saved into the Custom Palette, or renamed with a more meaningful name. The custom color created is named using the hex value that is displayed in the Pick a Color dialog. Only the Area dialog has the ability to rename custom colors and save custom colors into the Custom Palette.

LibreOffice uses the RGB color model for printing in color. The RGB values of a selected color are displayed below the preview boxes.

Using Area dialog

1)  Open the Area dialog and click on Color to open the Color page.

2)  In New, enter the RGB values or, if known, the Hex value into the text boxes. The color changes in the preview box to match the values entered.

3)  Alternatively, in New, use the minus and plus signs for the RGB values to decrease or increase the values. The color changes in the preview box to match the values entered.

4)  Click OK to change the color and close the Area dialog.

Adding custom colors

1)  Make sure the Area dialog is open at the Color page.

2)  Select the custom color that is displayed in Recent Colors.

3)  In Custom Palette, click on Add to open a Name dialog.

4)  Enter a new name for the color in the text box.

5)  Click OK to save the changes and close the Name dialog. The custom color appears in the Custom Palette.

6)  Click OK to close the Area dialog.

Renaming custom colors

Only a custom color can be renamed using the Area dialog as follows:

1)  Make sure the Area dialog is open at the Color page.

2)  Select the custom color that is displayed in the Custom Palette.

3)  Click on Add to open a Name dialog.

4)  Enter a new name for the color in the text box,

5)  Click OK to save the changes and close the Name dialog. The custom color appears in the Custom Palette.

6)  Click OK to close the Area dialog.

Notes

Renaming a custom color does not actually rename the custom color, but adds the custom color to the Custom Palette with a new name.

It is important to use a memorable names for custom colors so that they can be easily recognized in the Custom Palette. By default, a custom color is given a hex number, which makes it difficult identifying colors when there is more than one custom color.

Deleting custom colors

Only a custom color can be deleted using the Area dialog as follows:

1)  Make sure the Area dialog is open at the Color page.

2)  Select the custom color that is displayed in the Custom Palette.

3)  Click on Delete. There is no confirmation given when deleting custom colors.

4)  Click OK to close the Area dialog.

Bézier curves

In LibreOffice, Bézier curves can be used in a drawing. A curve is defined by means of a start point, an end point, and, where necessary, control points. For points on the curve the terms Nodes and Anchors are often used. For more information and an explanation of the mathematical background of Bézier curves, see https://en.wikipedia.org/wiki/Bézier_curve.

Bézier curves are very useful for experimenting with the shape and form of curves. In point mode the curve alignment can be changed by dragging the points with the cursor. In the example shown in Figure 35, the curve leaves the start point P0 in the direction of the first control point P1 and arrives at the end point P3 from the direction of the second control point P2. The more distant a control point is from the start or end point, the smaller the curvature at that point.

Figure 35: Example of a Bezier curve

  2. Control point (P1)

  3. End point (P3)

  4. Control point (P2)

Figure 36: Edit Points toolbar

Figure 36: Edit Points toolbar

Drawing Bézier curves

1)  Click on Curve in the Curves and Polygons panel in the Shapes deck on the Sidebar, or Curves and Polygons on the Drawing toolbar.

2)  Click at the start point for the curve and drag the cursor to the approximate position of the end point for the curve.

3)  Release the cursor and drag the end point of the curve to its end position.

4)  Double-click when the end position of the curve is reached and a curve is drawn. The arc of the curve is determined by the distance dragged to create the end point.

5)  Switch to points mode using one of the following methods:

6)  Open the Edit Points toolbar (Figure 36) using one of the following methods. The Edit Points toolbar does not become visible until a point has been selected on a curve.

7)  Click once on the curve to display the start and end points. The start point of the curve is larger than the end point.

8)  Click on a start or end point to display the control points. Control points appear at the end of a dashed line connected to the selected point, as shown in Figure 37.

9)  Click on the control point and drag it to a new position to change the shape of the curve.

10)  When the shape of the curve is correct, release the mouse button to fix the curve.

11)  Click anywhere on the workspace to deselect the curve and stop editing points.

Edit Points tools

After the initial opening of the Edit Points toolbar, when an object is selected that has been converted to a curve or polygon, the toolbar is displayed. The tools available on the Edit Points toolbar allow the editing of a Bézier curve and changing of the curve shape. A point on a Bézier curve has to be selected for all the tools on the Edit Points toolbar to become available.

Move Points

Click and drag on a point to move it to another location.

Insert Points

Activates the insert mode when selected and inserts smooth points onto a curve. Insert mode remains active after inserting points. Select Move Points to deactivate insert mode.

Delete Points

Deletes selected points. If several points are to be deleted, hold down the Shift key whilst selecting points and before clicking on Delete Points.

Convert To Curve

Converts a curve into a straight line or a straight line into a curve (Figure 37).

Figure 37: Example converting curved segment to line

Figure 37: Example converting curved segment to line

Close Bézier

Closes a freeform line or curve by connecting the start point with the end point creating an object with area fill.

Split Curve

Splits a curve into two or more curves. Select a point or points and click on Split Curve to create separate segments of a curve. Deselect the curve, then select a segment to move or edit it.

Corner Point

Converts a selected point into a corner point (Figure 38). Corner points have two movable control points independent from each other allowing a corner to be created in a curve.

Figure 38: Example of a corner point

Figure 38: Example of a corner point

Smooth Transition

Converts a corner or symmetrical point into a smooth point (Figure 39). Both control points are parallel aligned and can only move simultaneously. The control points may differ in length, allowing the curvature degree to be varied.

Figure 39: Example of a smooth transition point

Figure 39: Example of a smooth transition point

Symmetric Transition

Converts a corner point or a smooth point into a symmetrical point (Figure 40). Both control points are parallel aligned having the same length. These control points can only be moved simultaneously and the degree of curvature is the same in both directions.

Figure 40: Example of a symmetric transition point

Figure 40: Example of a symmetric transition point

Eliminate Points

Allows selection of several points before using the Delete Points tool. This is useful when deleting a straight line segment to create a complete curve.

Adding comments

Comments in Draw are similar to comments in Writer and Calc. For more information about adding, navigating, and replying to comments, see the Getting Started Guide.

Comments in Draw cannot be printed. To reply to a comment in Draw, a new comment has to be added.

1)  Go to Insert > Comment on the Menu bar and a comment box (Figure 41) appears in the upper left-hand corner of a drawing. Draw automatically adds the user name and date at the bottom of the comment and places a comment marker on the drawing page.

2)  Type or paste a comment into the comment text box.

3)  To apply basic formatting to the text, right-click on the text and select the formatting option from the context menu.

4)  To delete a comment, use one of the following methods:

Figure 41: Example comment in Draw

Figure 41: Example comment in Draw

5)  To move a comment, click on the comment marker and drag it to a new position.

6)  To hide comments, use one of the following methods:

7)  To show comments, go to View > Comments on the Menu bar and click on the comment marker.

Note

For the user name and initials to appear in a comment, enter the user data in Tools > Options > LibreOffice > User Data dialog (macOS LibreOffice > Preferences > LibreOffice > User Data). If more than one person edits the document, each author is automatically allocated a different background color.

Coordinate system

X and Y axes

The x-axis is the horizontal position of an object and the y-axis is the vertical position of an object. The rulers do not show a minus sign if there are negative coordinates. However, the minus sign for negative coordinates is shown in the position field in the Status Bar and the Position and Size dialog.

Workspace

The Workspace in Draw is larger than the drawing page. The area outside the drawing page is one page width right and left and a half page above and below the drawing page. The size of the drawing page is indicated by highlighted portions in the horizontal and vertical rulers.

Draw objects can be drawn partly or wholly outside the drawing page and these objects are saved with the drawing. However, when the drawing is printed or exported, any object or portion of an object not on the drawing page is not included. This allows the Workspace area around the drawing page to be used for drafts when creating objects.

Object position

The coordinates of objects and snap guides are shown relative to the origin. The default origin for coordinates (0.00/0.00 position) is the top-left corner of the drawing page without margins or the top left corner of the drawing page where the margins intersect. To change the default origin, click and drag the intersection of the rulers in the top left corner of the Workspace to the desired position. Guide lines appear as the intersection is dragged from its default origin to its new position. This origin setting is only for the current view and is not saved in the document.

The area inside the default origin is the area used for the grid when the option Snap to Grid and Display Grid are selected.

To reset the default origin back to its original setting at the top-left corner of the page, double‑click in the top-left corner on the Workspace where the horizontal and vertical rulers meet.

Accuracy

Draw internally uses integer values in 1/100 mm. Therefore, for example, it is not possible to get an exact position for 1/8 inch. Also, many dialog fields are restricted to two decimals.

To work with the maximum possible accuracy, go to Tools > Options > LibreOffice Draw > General (macOS LibreOffice > Preferences > LibreOffice Draw > General) and set the option Unit of measurement to Millimeter. The rulers show metric units after this option has been selected, To use another measurement unit for the rulers, right-click on a ruler and select the measurement unit from the context menu. The horizontal and vertical rulers can have different measurement units.
