Commonly Used DLLs and Routines

Tolerances

Draft Angle Tolerance (dcsTiDraftAngle):

This routine is designed as a Tolerance to simulate Draft Angle deviation. This routine provides one contributor for Rotating. The routine rotates the selected features as Draft Angle around reference center point.

Moves

Morphing CGR and Bend Routines (dcu_Autobend.dll):

The Autobend DLL features moves that handle components and assemblies that are over-constrained on the primary plane. These routines provide several ways to handle over-constraints using some automated rigid-body methods.

HighPoint: Locates object on highest primary locators. Use this routine when you want to locate over-constrained object(s) on the highest primary locators.

Move by Value (dcu_xformMv.dll):

The purpose of this module is to allow parts or features to be translated, rotated or transformed by a specific amount. This amount can be a specified as a constant value or a calculated value from a measurement.

Project Point to Feature: Projects a point to specific feature along a specified direction.
