Combine

Combines two or more selected objects into a single shape. Unlike grouping, a combined object takes on the properties of the lowermost object in the stacking order. You can split apart combined objects, but the original object properties are lost.

When you combine objects, the drawing elements are replaced by Bézier curves and holes appear where the objects overlap.

To access this command...

Choose Modify - Combine (Collabora Office Draw only)

Select two or more objects, open the context menu and choose Combine.
