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?

Ciao @WANGHUA198211

 

As @StevenVickers says, the curves are too big. Try to scale these as I do (0.001x) and it all works!

 

Ciao

Hi, Steven,

 

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
