Rhino, Object Won't Split, be trimmed, or cut :(

I have created this geometry using grasshopper but it won’t split, and I tried everything, but couldn’t solve it. Can anyone help? Thank you in advance for whoever tries.Rhino Object.3dm (599.9 KB)

Hi John - the object is small compared to the file tolerance (.01 meters). The length of the short edges in the trimmed holes are about tolerance. So, set the file tolerance to .001 or even a bit smaller and intersections and trimming etc should work better.



Thank you so so so much!
