Importing step files in Siemens NX 11

You can import the stp files by using step/stp import function.

Command path: File => Import => Step

You can have some problems while importing the stp files into NX. Options changes imported data.

Import From: Select stp file to import.

Import to Part: Define stp files will import in an existed file or New file will be created for stp file.

• Work Part: Stp file will be inserted in an existing part

• New Part: The new part will be crated for stp file.

Model Data: Select which model data will be imported. Unselected data won’t import. (Curves, Surfaces, Solids, Coordinate systems, Product data, PMI)

Sew Surfaces Automatically: Sometimes there might be some tears or gaps between surfaces. NX can’t form a solid body because of these gaps. (STP file consists of the solid body but NX converts solid body to sheet body because of these gaps.) “Sew Surfaces Automatically” function sews disconnected surfaces and forms the solid body.

Simplify: Simplifies 3d model.

Optimize: Optimizes model. I prefer to unclick this option. If it is needed to use “Optimize Face” it can use after model opened.

Flatten Assembly: Assembly stp file will open in a single part and all components will be a solid body in the new part. (It might be useful if the model will use in assembly with no change)
