Tip: Shrinkage and UDFs
If a feature that is included in a UDF has dimensions which have had shrinkage applied to them, the feature is stored in its unshrunk state. If a destination part, in which a UDF has been placed, has been shrunk using All Dimensions, new dimensions for the group are shrunk with the shrinkage factor of the part.
