Mesh Outline with Clipping Plane?

Rhino Rhino for Windows
1

Hello! I am using the clipping plane to slice a mesh in half at different dimensions. I want to mesh outline the mesh at the section and below.

I tried splitting the mesh that the section cut. But the mesh outline does not outline the lines at the section, only the base outline.

Any suggestions?

I’d try the Section Tools plugin which will make curves on new layers for each section you add. There are a lot more options than clipping planes so check out the Help pdf on the page as well.
