I'm really about to show my ignorance here, but hey, we've all got to learn.

I've downloaded a trial version of MeshCAM, and imported a very simple STL file I'd created (a 1/4" thick sheet with a circle cut out of it).

Generating a toolpath with MeshCAM was fine, and I can load this into Mach or CNCSimulator and see what would happen.

MeshCAM looks ideal for producing pseudo 3D parts - textured surfaces, engraving etc. However, what would I use if I just wanted the cutter to follow the path of the geometry? I ask because I was sort of expecting the CAM program to create a simple cutting path - a circular cut to make a hole, then a few straight paths to cut out the sheet.
