Clash detection bugs in single model

[BIMvoice]

Many false clashes showing up here. I think for some of them is shown the touching area (since is shown as few meters). Can come back with more feedback once the very obvious issues are sorted.

I attach for fun also a bcf :)

Off all the issues created by me, this one is the most important right now, please focus on this before the others @louistrue . Thank you :)
