Importing stp file in the NX Continuous Release

You can import stp files in two different methods in NX Continuous Release.

  • File => import => stp 214, stp 203, stp 242
  • File => Open => Change “Files of type” as STEP files (Click options in the open window to change import options. Shown in the figure)

Import Options are very important in NX. Most of the problems occur because of the settings in the “Import stp” options. You might have missing parts, surfaces, bodies, or curves in the opened stp file, because of these settings. 

Note: In the previous versions, surface or body deselected by the default setting. (I can not remember which one deselected) According to these settings sometimes empty or missed features or parts might occur in opened stp files. 

Import to Part

  • Work Part: Stp file will import in the opened NX file window. No new file will be created.
  • New Part: The new part will be created for the stp file. 

Model Data

  • Curves: select to import curves and points into the model. Sometimes performance problems might occur because of this setting if there are lots of curves in the model. 
  • Surfaces: Select to import surfaces and facet features in the model. 
  • Solids: Select to import solid bodies.
  • PMI: Select to import GDT, Dimensions, or notes in the stp file. (If they exist in the stp file)

Options

  • Sew surfaces Automatically: Sews contacted surface edges automatically.  
  • Flatten Assembly: Transforms assembly stp file to the simple part file. The parts in the assembly file will be solid bodies in the part file

Important Notes

  • If there is no solid body in the closed surface, activate “Sew surfaces automatically” when importing stp file.
  • Sew surfaces automatically, Simplify, Optimize, Smooth B-Surface, Flatten assembly options might change stp model. Be careful when using these options.
