Repairing STL or Vericut Model File Normals¶

Use the PolyFix Converter and the procedure below to repair surface normal vectors of STL and Vericut model files. PolyFix repairs the surface normal vectors to ensure they point uniformly outward from the model surface.

Note: Surface normal vectors can also be repaired via batch processing.

To repair STL/Vericut model file surface normal vectors:

Access the PolyFix Converter window: in Vericut select File tab > Convert dropdown menu > PolyFix.

You can also run this converter outside of Vericut via the "polyfix" command file located in the Vericut "commands" directory, under the directory representing your computer type.

Type the /path /filename in the text field, or use the Browse button and use the file selection window that displays to select the Input File containing the surface normal vectors to repair.

Type the /path /filename in the text field, or use the Browse button and use the file selection window that displays to select the Output File to receive converted geometry.

Choose the Input File Type appropriate for the model being repaired.

Choose the Output File Type and Output Format Type in which to write the repaired geometry.

Click Process.

Error and informational messages from the process are sent to the PolyFix window message area, and to a log file named "polyfix.log" created in the working directory.

Tips:

PolyFix-corrected model files can be used in Vericut as solid stock, fixture, design, or NC machine shapes. It is a one-time effort to repair an inconsistent model file.

After repair, use the "Outward" surface normal option when referring to the repaired model file in Vericut.
