When mapped to a CAD property, the Description system-defined attribute in aPriori is set to the value of its corresponding CAD property only when the CAD model is first opened and GCDs are first extracted. It will not appear in the Cost Overrides dialog and will not be subsequently updated from the CAD property again. This ensures that if this is modified in aPriori, the modified value will not be overwritten by the CAD property.

Note that this behavior may change in a future release.
