Just getting into Schedules (after 2 years of using Revit ) and it is very impressive.
However I was wondering if anyone could explain why say, window families created as generic models, inserted into walls successfully and then later changed category to 'Windows' via the Family Editor->Settings->Family Category & Parameters show up as question marks when tagged in plans/elevations rather than receiving a number.
It is probably something simple but at the moment I can't see it.
