Datum Optimizer (AAO) is a tool designed to determine the optimal datums from a candidate set with the goal of minimizing the rigid part variation or compliant part deformation.

Sequence Optimizer (AAO) is a tool designed to reduce lead and launch time by eliminating or minimizing manual join/clamp sequence studies. The Sequence Optimizer determines the optimal join/clamp sequence from a candidate set of joins/clamps. Users may optimize clamp sequence or joining sequence.

Dimensional Distance Measure measures the distance between two selected features in three modes: Center Distance, Minimum Distance and Maximum Distance. These new measures will produce similar results to various CAD Measurements tools.

Volume Measure This routine calculates the surface volume of a closed surface. Users can utilize the User-DLLs Zip Pair Points (dcsMvZipPairPoints) and Zip Surfaces (dcsMvZipObjectsToTargets). These User-DLLs will sew features to create a shell of the part that will measure the volume of the closed surface.
