How to fine nibs within meshes

Rhino Rhino for Windows

i am stuck with trying to find nibs within meshes… when I go to cut something into a pendant it comes up with a message you can not combine nibs with meshes…

I’m just going to assume that nibs are NURBS. . . .
Use SelMesh to select all meshes in the scene. Then run Invert.

Thanks… New at this and also very old trying to learn new things to pass along to my students. Will get better with the help of people like you, if I live long enough:-) thanks.
