Yikes, really freaks you out when your model starts to behave in weird ways. Then I found out about probs with components with duplicate names. I have many DC I need to duplicate, and each one contains about 30 groups. Currently I copy a component to a new sketchup instance and manually change all the names. Is there a utility that will look into the model code and let me do a search & replace?
While I am on the subject of names, I am perplexed at the number of places we can actually enter names. Names in Entity Info are different from names shown in the Component Attributes window (file attached). I haven't a clue what Definition Name is all about, except the SU throws crap in there and I have to rename that as well. I end up repeating the same name 3 times.
