I have a problem for imported IGES file in NX11,
I tried to extrude from curves insde the imported file,
But i got error "The input section is not valid", as picture below,
You can get the .prt in attached file,
Could anyone can help me to check the reason ?
Solved! Go to Solution.
A single curve is nearly half a kilometer long, tangent curve get to more than a kilometer.
Assume the units were incorrect in the iges file, or is this a large construction project?
did you try to add the curves to a sketch and use then the optimize curve?
Thank you for your feedback,
I just exported to IGES file from ICEM CFD for HEX meshing exercise in NX.
Maybe it is unit error
