How can I create intersecting surfaces/solids without keeping the corresponding intersection?


There is the 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 is created between two objects, here with the "New Compound Solid" command:

Figure 01 - Creating Compound Solid and Thus Intersections

In this specific case, the cylinder is subtracted from the cuboid, thus creating an intersection:

Figure 02 - Create new solid by subtracting the cylinder from the cuboid

Figure 03 - New solid with an intersection

2. This intersection is now "converted to 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 to modify existing ones. You can change the boundary lines of a surface by selecting it again. In particular, the intersection area must be modeled as a quadrangle area:

4. Finally, you have to create the solid again:
