FAB 3000 is shipped with the most common aperture rules for compatibility with older CAD systems. However in the event that you have an aperture file that does not load into FAB 3000, you may use the feature Aperture Rule Wizard to create a custom rules template which will allow FAB 3000 to read-in your specific aperture files. Please go to menu: Setup | Aperture Rules Editor...
Note: Registered users can send us any Aperture Files that won't load, and we'll be happy to create the "Aperture Wizard Rule" for them at no cost. Please submit a support ticket and attached your files.
