Introduction

the cutting plane and the resulting cross section

Cross Section

This Script creates a cross section of selected meshes:

• Create a couple of meshes that you will want to cut
• Create a plane, passing through them. It will be your cutting plane. It can be any object, but it must have only one face.
• Select the meshes, then, with shift, select the plane. The meshes will still be selected, and the plane will be active.
• Run the script
• Voilà! the meshes are cut at their intersection with the plane, and a new object is created containing the section. (In this image, I moved the section away for clarity)

Known issues

• You must have been in Vertex or Edge mode when you apply the script. If you have been in Face mode, the script won't be able to fill the section.
• You will get wrong results if some edges are coplanar with the cutting plane. Try moving the plane a little bit so no edge are directly on it.
