Intersecting Surfaces/Solids Without Keeping Intersection

There is an option to convert an intersection to a line. This option allows you to create the intersection manually. Here is an example:

1. First, an intersection between two objects is created, here using the "New Compound Solid" command:

   Creating Compound Solid and thus Intersections
   In this specific case, the cylinder is subtracted from the cuboid, thus creating an intersection:

2. This intersection is now "converted into lines". For this, select all involved objects and in the shortcut menu, select "Convert into Line" under "Intersection":

3. The new lines are used to create new surfaces or modify existing ones. You can change the boundary lines of a surface by selecting them again. In particular, the intersection area must be modeled as a quadrangle surface:

4. Finally, it is necessary to create the solid again:
