Clipping > Create, Both (Trim Menu)

This command can be used to create two disjoint clipping surface that leave only the outside or the inside visible.

The objects which are to be clipped are chosen. Click on objects to choose them.

Any fillable object can be identified as clipping surface.

Many object types can not be converted cleanly into a surface. The precision of the conversion can be specified using the command Drawing Settings > Precision in the entry "Transform".

In this command's parameters, you can specify for the "Inside" case whether the result shall be optimized. If so, only objects that lie within the visible area of the clipping surface become part of it. This requires less storage space and computation time, but also means that when the visible area is changed (or when the clipping is resolved) afterwards, objects that were previously invisible will not necessarily become visible again.
