The PATRAN 2 Neutral file is supported by MSC.Software Corporation’s Patran.

With the PATRAN 2 neutral file, Patran can import or export only parametric cubic geometry by executing the File/Import menus on the main form.

Patran cannot export non-parametric cubic geometry using the PATRAN 2 Neutral file. Instead, you may use export the entire geometry model using the IGES file.

Depending on Geometry application methods used to create the geometry, you may or may not be able to create parametric cubic curves, surfaces or solids. Also, some geometry Create action methods can generate only parametric cubic geometry.

For information on how to import or export a PATRAN 2 Neutral file, see Importing PATRAN 2.5 Neutral Files, 93 and Exporting to a PATRAN 2.5 Neutral File (p. 197) in the Patran Reference Manual.

For the definition of parametric cubic geometry, see Parametric Cubic Geometry.

For information on what types of curves, surfaces and solids you can create in Patran, see Table 1‑1, and starting on (p. 28).
