Applying Shrinkage by Scaling
Shrinkage by scaling is applied by creating a new feature of type Shrinkage. When you apply shrinkage in Mold or Cast mode, the Shrinkage feature is created in the reference model, not in the design model. Therefore, if shrinkage by scaling is applied in Mold or Cast mode:
• It is never reflected in the design model.
• If shrinkage by scaling is applied to the design model in Part mode, then the Shrinkage feature belongs to the design model, not to the reference model. Shrinkage is accurately reflected by the reference model geometry, but it cannot be cleared in Mold or Cast mode.
• Shrinkage by scaling should be applied prior to the definition of parting surfaces or volumes.
• Shrinkage by scaling affects part geometry (surfaces and edges) and datum features (curves, axes, planes, points, and so on).
