(I'm quite new at Revit so apologies if my concepts are a bit inaccurate)
I have heard using, in-place models in Revit projects is poor practice since it can slow down a large project. However I noticed Revit also organising inplace models lumping them with the rest of the families. So my question is:
Is there really any performance penalty/benefit to be had by inserting families from an external file as opposed to creating inplace models in a Revit project?
