The way we construct our assemblies is via plane driven extruded virtual parts. These require a special code which holds the length and special dim A etc, (RAD-Code shown below). The length is also gathered by referencing a driven sketch as are the dim A, B etc, but on certain machines the length reference is substituted by a set dimension which doesn't update post plane changes. This doesn't happen if the length property is in the configuration specific but does when in custom, the preference is to have the data in custom as there maybe more than one configurations and the data is acquired in the same way for all.
Is there a setting which is causing certain machines to change this data when others are happy for it to remain as a driven dimension reference?
