The inner intersection of two primitives of different shapes and one of the primitives can be removed by the subtraction function.

Entry: Top Menu - Edit - Subtraction.

As shown in the figure below, the rectangular part passes through the subtraction and deletes the part that does not need to be preserved.

Figure 8

Note: The part where the subtraction is eliminated is based on the drawing order of the primitives, and the later drawing will be eliminated.
