I use the Boolean Node in Geometry Nodes. I want to use a curve object (converted to mesh via Curve to Mesh node), but it doesn't work. Anyone have any idea?

Here's the Blend File

  • $\begingroup$ tbh i think it is a bug - if i exchange both entries in mesh boolean, it works, so i think it is a bug $\endgroup$

  • $\begingroup$ Thank you all of you. Fixed !! Also if I put the curve and curve to mesh in same geo Node, it can be fixed as well $\endgroup$

The Normals of the Curve get inverted for some reason.

It seems like a bug, but to fix add a Flip Faces node.
