Trim Curve with Brep not giving a result for inner curve?

Hi all,

I’ve been having a problem with the Trim with Breps component. Please see the gh file attached. For some instances, they work exactly like how I would expect. But for others, there doesn’t seem to be an output for the “inside” splits.

This is really strange to me as the geometry is exactly the same, except rotated by 90 degrees.


Hope someone out there can help me out. Thanks!

P.S I am using Rhino 5. (28.5 KB)

just as info, it works like a charm on Rhino7

Thanks, spent an embarrassing amount of time trying to figure out why it wasn’t working :sweat_smile:

btw, just in case anyone comes across this and needs the info. Rhino 6 solves the issue as well.
