Without some examples its hard to pin point the problem, but most likely some of the sub-components have the same definition names. You will need to edit each component created from the first one by changing the saved definition names of the subs as well as the parent. Another possibility is using a common attribute with different formulas in swapping components, but I don't think you are swapping In regards to the warehouse, there is a hidden attribute which your copied components have inherited. This can be viewed in Attribute Inspector and then deleted. http://sketchucation.com/pluginstore?listtype=1%26amp;author=0%26amp;category=0%26amp;search=attribute%26amp;submit=%3Fare you When creating copies it is best to use the generic term Parent!anAttribute instead of mycomponentname!anAttribute

I assume you are using Save_As on a DC, or exporting your DCs as part of a Collection. The SKP file[s] that results might appear like a normal 'Component', but if you then add it to a Model it will display the DC attributes/properties you gave it when you made/saved it. The various 'dynamic_attributes' which you gave it within its 'cradle' Model, are saved with the external SKP itself, when you do the Save_as etc... So when you upload a DC SKP it should retain its special abilities as attributes attached to its own model. When you download a DC it still has those abilities saved within it, but they do not display if you simply open that downloaded SKP - they only manifest themselves when you insert that DC into another Model... It is a Dynamic Componentafter all... the clue is in the name...

TIG, Every suggestion you have made works perfectly; the issue was actually with my system. I am running OSX and it turns out that when smart quotes are enabled sketchup does not recognise " as a valid symbol. I discovered this when I copied and pasted code I found online it worked but when I retyped it, symbol for symbol, it did not. Very weird In order to fix this I needed to do the following: System Preferences -> Keyboard -> Text -> uncheck "Use smart quotes and dashes" This is something that I am sure trips up many OSX users and should probably be looked at by Sketchup. Thanks again for all your help. Brad
