Brep CP bug?

Dear people¡I'm experimenting what seems to be a bug getting Brep CP.In the attached image you will see the evaluated vertex cloud and the displacement vector to what I expected to be the Brep CP, but form those vertex below the brep it finds the CP in the nearest edge, not in the nearest face, being closer to the face than to the edge though.Can any tell me whats happening, maybe I'mdoing something wrong.Thanks, ASee More

Hi Antonio,

it was more than 4 years ago, so my memory is a little vague. I think I constructed the buildings as polysurfaces, and then meshed them. This added the irregularities in the joining parts. Then I relaxed the mesh (think Kangaroo, even though it did not exist back then) and extracted the wireframe. While relaxing, the top and the bottom were fixed. They originally already had that circular form. Does this explain enough?

Hey Antonio,

 

The geometry gym group is probably best place to ask questions, then I can attach files etc.  http://www.grasshopper3d.com/forum/topics/extruding-profile-through-a  might help you with orienting a profile to a surcace (surface normal closest to path curve mid point).  I can add mesh if needed, but I'm sure in your case you can generate the underlying cylinder.

 

Let me know if it doesn't help.
