The Family has been Renamed

This warning message is probably familiar, troublesome and annoying.

I was reading a couple threads at RFO; THIS ONE and THAT ONE.

Apart from workset related issues I’ve written about before, I believe the underlying cause of renaming is that Revit perceives a family as different. That’s not very surprising but I think that the actual difference is the result of different versions (2016 vs 2017) or having Save As used on the family (to put it in a different folder)…AND any operation that involves Copy/Paste, which includes the Insert from File tools.

When Load from Library > Load Family is used I only see it occur when worksets are being used (see the links at end of this post). The families merely having some different parameters (either instance or type) generates the dialog asking how we want to deal with the existing definition.

Using Revit 2017.1 and passing a family from one…
