I found a weird glitch where if I take this brep:
… and then convert to SubD in grasshopper, I get a broken vertex in one spot, like this:
For some reason, if I rotate the referenced brep in Rhino a little bit, it fixes it:
Any idea why this would happen?
Here’s the definition used to convert it, with internalized data. There’s a curve object you can highlight to create a bounding box around the problem area so you can find it, and a stream filter to toggle between the input brep and the slightly rotated input brep.
