I have some sheet bodies, imported from both IGES data, and Parasolid data. When I try to sew any two of the sheets, I'm told they are disjointed, and to try a looser tolerance. I've bumped the tolerance up to .010, and it still won't sew, but when I measure from edge to edge, I get a min 3D distance of 0.000005, same for min local distance. It doesn't seem to matter which two I pick, they won't sew.
Any thoughts?
