Classify Surfaces by Pull Direction in Mold Design and Casting
You can classify surfaces into core, cavity, and undercut regions.
Release: Creo Parametric 4.0
Benefits and Description
You can watch a video that demonstrates this capability.
You can classify surfaces into core, cavity, and undercut regions. The surfaces that cross over core and cavity regions are split when you select the Silhouette Split check box. As a result, it takes less time to collect mass surfaces and it is easier to visualize parting surfaces on the model.
