Hi Peter,

What is it you’re trying to split? If you’re trying to split the main object which is grey in your screenshot, the yellow surface needs to extend past the edges of the grey object in order for the command to work.

If you’re trying to split the yellow surface with the grey object then it may not be a closed object. Use the command ShowEdges to see if it highlights any errors.

You can also try a couple of other commands to speed up that process:

I hope that helps

Hi Peter,

My first suggestion would be to use the command _Intersect and see if it creates a clean intersection. You can sometimes use that command and the curve which it outputs to then split the surface.

Can you share the model on here?
