First, I think FreeCAD is all right, just I don't know how to use it...
I have a part created in other application, consisting of NURB surfaces that is supposed to be airtight. It was imported from IGES format.
But there are gaps between surfaces (see below).
I think that one problem is that two BSplines, even with the same poles, give different shape because of pole multiplicity.
The other problem I noticed when zooming: looks like coordinates of poles that should match are slightly off
(see control point with multiplicity 1 two images up
and control point with multiplicity 4 on the image above)
I attach project in case anyone would like to look into it.
I believe it's the problem of the other application... but what can I do to fix this model?
Thank you for your suggestions!
