Brep/Plane Intersection Partial Success

Hello,

I am using the Brep/Plane Intersection command and 4 out of the 5 intersections work perfectly to
waffel struc. attempt.3dm (3.9 MB)
waffle struc. attempt 17.02.09.gh (12.5 KB)
produce closed planar curves. The one in the middle, however, only produces a line at the bottom of the Brep and fails to intersect all the way around.

Why is this happening?

Oops, didn’t mean to upload the documents in the middle of the text!

You can visually confirm that they are actually not touching.
And I really don’t think it is necessary to make 10000+6000 planes to test that.

The problem is the middle intersection that lies exactly on the tip of the cone, not the exterior ones.

I tried yesterday some workarounds and could not find any. The intersection also fails in Rhino.

Let’s call this a bug ?

Yea, for some reason the problem is due to it being right in the middle and touching the tip of the cone… guess it could be a bug because with other geometry it works fine.

If it’s not a bug and someone knows how to fix it please help!!

It works in Rhino WIP !

Aha so it is a bug!
Thank you 1) for giving it another try and 2) for showing me what WIP is, I wasn’t aware of it.
