Dave,
Thanks for your time and input.
Your example was most illuminating, and having looked at it briefly I think I see how it works, but can't see how I can utilise it in my situation.
My DC's are cabinets of different shapes and sizes with different codes for each one. On each of these I place doors which are a seperate range of DC's.
I have created various reports for quotes and cutting lists, the information for which (including colour from the 'Material' attribute) is taken from the DC.
There are about 20 different cabinet colour options and 40 different door colours that can be used.
If I place 20 or 30 different components in a model (made up of cabinets and doors) I would like to be able to change the colours of some (pre-selected) or all the cabinets at once, likewise the doors, and have that change updated in the DC material attribute so the correct colour is used in the reports. At present I have to do every one individually which is tedious
A plugin to do this I am sure would not be too complicated for an experienced coder (which I am not), but I could be wrong
