Body Intersection

For the body intersection multibody technique, you use the Combine feature and its Common option.

Body intersection is a quick way to create complex parts with very few operations, which can result in faster performance. The operation takes multiple solid bodies that overlap one another and leaves only the intersecting volumes of the bodies. For most models that can be represented fully by two or three drawing views, this technique can be used by intersecting either two or three extruded solids. The extrusion sketches are the solid lines represented in the two or three views.

The following example shows this technique with the intersection of two extrusions.

To create the part described above, you begin with the base part:

And then select the Common option of the Combine feature to use only the overlapping material of the base part.
