Hi Michael,

I use MOi to create the parts files for the tube bender 95% of the files go through without problems sometimes I find they dont import I make sure that when I create the path curve the direction or the start of the curve is all the same way. If i import the dxf path into solidworks and export the same file from SLD the step imports no problem. What is the STP format that MOI uses? Both files exported and overlayed look exactly the same so it must be an export issue.

Any advice welcome.
