Waffle structure model, unable to fitted the plane

[Nico_smith (nico)]

I am a beginner of Grasshopper, and I am trying to make my waffle structure. I am not sure why I can’t extract the outline of the plane.

Hi!

The problem is that Plane fit cannot construct planes from the points provided to it by the vertices output from Deconstruct Brep. Look here:

Some of the points are are not from planar Brep faces (A) and sometimes there are not enough points to define a plane (B). You need at least 3.

This will solve your problems:
