Have you tried importing with the healer on (or off, as may be the case)? If
the shape is complex I can't recommend use of the healer in IV, but try it in
MDT where you can turn off the spline tangency healer option and increase the
Simplify tolerance a couple of hundred thou or even up it to .001. It will
sometime help.
Also, while in MDT, run AmSanityCheck on the part (but you knew that, didn't
you ).
