General rules for mapping CAD properties

The following information applies to both UDAs and production inputs.

Multiple Mappings and Precedence

It is possible to map more than one CAD property to a UDA or a production input. This is useful where more than one CAD property for the same attribute exists and is populated in the CAD file. For example, a company's use of CAD properties might evolve over time, so that different properties may be present in parts of different ages or from different organizations within the company. Or the CAD file may specify both a "Material" and an "Alternate Material" field. Precedence in aPriori is determined by the order in which the mappings occur in the XML file: the first mapping that succeeds "wins".

Overriding Mapped Values

Your users can override mapped values in aPriori to explore the cost impact of different manufacturing scenarios.

You can override mapped values in the following ways:

  • Enter a different value in the Cost Guide (or in the Cost Object Info dialog).
  • Specify a different value in the Bulk APrioriCIGenerateUser interface or spreadsheet

Once a mapped value is overridden, the override value continues to be used for subsequent costings, unless it is cleared.  There are two ways to clear an override:

  • Use the Cost Overrides Summary dialog
  • Using the Reconcile Inputs dialog.
