After importing a STEP or IGES to get an un-parameterized body into NX, you might find some consistency errors reported via Examine Geometry which would cause drafting views to display incorrectly, section views failing, or Sew operations in Modeling to be unsuccessful. How do you fix this problem?
The method below will fix most of invalid geometry, although it is not guaranteed in every case.
Go to Insert --> Synchronous Modeling --> Optimize --> Optimize Face option --> Toggle on Clean Body before Optimize
Select the body either from Part Navigator or rectangle select it from the screen, so all the faces in the body will get selected. Press OK to complete Optimize Face operation on the body.
After Face Optimization, check with Examine Geometry to see that Consistency issues are resolved.
Note: Optimize Face
command is to simplify surface types, merge faces, improve edge accuracy.
