IGES File Reader Options

Setting the IGES file reader options

1. Go to Tools, Global Options, IGES

   The IGES dialog is displayed

   

2. Enter the Faceting Factor (the value must be greater than 0). The higher the value, the more JetStream will facet rounded entities and therefore the smoother they will appear. See for more information.

3. Enter the Max Facet Deviation . This will facet entities to within the specified tolerance. See for more information.
