Convert to 3D
Converts the selected object to a three-dimensional (3D) object.
If you select two or more objects and convert them to 3D, the result is a 3D group that acts as a single object. You can edit the individual objects in the group by choosing Shape - Group - Enter GroupFormat - Group - Enter Group. Choose Shape - Group - Exit GroupFormat - Group - Exit Group when you are finished.
Converting a group of objects to 3D does not change the stacking order of the individual objects.
Press F3 to quickly enter a group and Ctrl+F3 to leave the group.
You can also convert bitmap images and vector graphics, including clipart, to 3D objects. LibreOffice treats bitmaps as rectangles and vector graphics as a group of polygons when converting to 3D.
Even drawing objects that contain text can be converted.
If you want, you can also apply a 3D Effect to the converted object.
