Multiple Slicing

I have a large number of objects that I need to split on the same plane. In the attached, I would like to split all the circles on Z = 0.

Is there any simple way of doing this?

Hi Jim - select all the circles, and in the Right or Front view start CutPlane. First point at 0, then drag to the side using ortho. Use the resulting plane to split the circles.


I must be missing something how to use this.

Enter to stop making cut planes…


The problem I am having is the cuts are slightly off.

Rather than cutting at 0, they are cutting at 1e-15. I know that it is effectively zero but It is causing chain reactions downstream with things getting increasingly off.

What is it doing? You would have to multiply that “error” by about a trillion before it becomes significant relative to the file tolerances.
