Hey, I am working on an architecture project, but I am new to Rhino. I have been using the split tool just fine but now when I try to split a plane using my object, it says “Spilt failed, objects may not intersect or intersections may not split object." I’ve tried rebuilding the curves and surfaces but those didn’t seem to help.
Without a .3dm file with the geometry, or at least a good screen capture, it is impossible to offer any specific advice.
When Split or Trim fails the first step in diagnosing the problem is usually to Intersect the objects. The intersection curve should with be closed, or run without breaks between two edges. This is asuming “apparent intersections” are not being used.
I actually figured it out after trying different things. I realized that the object I tried to cut through the plane was not thick enough so I had to add thickness.
However, thank you for your response!
