Thank you to everyone that has helped me, I am a GH beginner.
I have divided a surface, and placed an extruded object along the division points of the surface. It works, except that the extruded objects on the left side only of the picture below are rotated (“crooked”) about the Y axis:
Thank you very much Gijs, that is definitely a simple fix.
SORRY BUT ONE MORE QUICK QUESTION - right now the extruded objects are attached to the Brep surface by the centroids of the extruded objects - is there a simple way to attach the extruded objects to the Brep by a base point (like the midpoint of one side of the base rectangle of the extrusion)?
PS - as to why this is so complicated, it’s because I am a total beginner and I’m just trying to figure it all out by trial and error. I never had any formal classes or anything, just feeling my way through it.
