How to make an interference line from 3D Faces?

A - answer How to generate intersection line between two non-complanar 3D Faces?

First convert the 3D faces (3DFACE objects) to surfaces with the CONVTOSURFACE command. Then use the INTERFERE command to generate the 3D intersection line.

In older AutoCAD versions you can also thicken the surfaces (THICKEN) and then INTERSECT them.
