In direct integration mode with Pro/ENGINEER, if the composition selection mode is MCAD, aPriori selects the MCAD composition from the part, if available. Otherwise aPriori selects the VPE default material (Steel, CR-1020).

In CAD-independent mode, aPriori selects the VPE default material (Steel, CR-1020 in aPriori starting point VPEs).

In both direct integration and CAD-independent mode, you can use aPriori’s selection or else manually select a material composition and override the material unit cost. To manually specify a material, select Edit > Material Selection in the Manufacturing Process pane (see also Selecting material in Manufacturing Process Information). You can override the unit cost if desired.

All material stock is virtual stock. Material Stock dimensions are given by the PSOs Thickness of Part, Length of the flat pattern’s Smallest Enclosing Rectangle, and Width of the flat pattern’s Smallest Enclosing Rectangle, together with the calculated or user-specified values for Width of Addendum Added to Blank Size [per side], Stock Length Margin, and Stock Width Margin (see also Material Cost and Utilization).
