You can use the Power Feature Trimming to:
Toolmaker uses Power Features to add fits and clearances into your model.
Parametric fit and clearance features are automatically defined for major mold components in all component catalogs. Parametric components include pins, sleeves, blades, screws, pillars, bushes, location rings and dowels. You have control over when and how fit and clearance features are applied. For example, you can make changes to the size or position of multiple components before updating the Power Features.
Ejector pins, sleeves and blades (and core and return pins) may be trimmed to the cavity impression. When Power Features are updated, a component automatically retrims if required. To retrim a component without updating all its Power Features, re-run Power Feature Trimming.
