Rename family names Dynamo 1.x

[SeanP]

Try not to post the same question to multiple locations. It makes it harder to get you and others and answer.

See here:

Ad prefix to the family type by dynamo and rename the family name and push the new names from dynamo to revit

The problem you are having is because you are just collecting the Elements (instances) of each type, not the Family Types nor the Families. See this post: https://forum.dynamobim.com/t/rename-types-with-dynamo/15071
