Extrude a solid along a path to make a new solid?

[martinsiegrist]

There are quite a few topics about cnc simulation.

Here’s how I would do it with an Anemone loop in Grasshopper:

Solid Difference

The file name is ball bit, hence I guess you want to simulate a toolpath. That is tricky when you feed the boolean difference with all the objects you want to subtract at once. My solution is a loop with Anemone. You can tweak the parameters to simulate step over. [image] ball bit 0.90_mrtn.gh (19.9 KB)
