Creating
Drawing toolbar
Before you begin creating 3D objects in your drawing, it is recommended that you add the
LibreOffice 3D tools to the Drawing toolbar as follows:
1) Right-click in an empty area on the Drawing toolbar and select Visible Buttons from the
context menu.
2) Select To 3D and To 3D Rotation Object from the available list of icons to place
them on the Drawing toolbar as shown in Figure 163.

Note
The To 3D, To 3D Rotation Object, and Extrusion On/Off icons only become
active when a 2D object is selected in your drawing.
Extrusion
Extrusion is a procedure that creates a 3D shape from a 2D object. The 3D geometry is formed by
extruding a polygon perpendicular to the plane of the given polygon using depth to create front,
back, and side faces. The side faces are formed by connecting all corresponding single edges of
the front and back faces.
Draw uses a default value for extrusion (depth) based on the size of a 2D object. This value can be
changed after carrying out extrusion; see “3D-Settings toolbar” on page 145 for more information.
1) Draw an object using one of the shape tools on the Drawing toolbar.
2) Select the 2D object you want to convert to 3D.
Note
Extrusion only works on basic shapes, symbol shapes, block arrows, flowcharts,
callouts, and stars that are included as a part of the default set of tools on the
Drawing toolbar. Extrusion can also be used on any text created using the
Fontwork Gallery.
