ok, not actually thousands of components! you have lots of instances, but with the others added you'll only have a hundred or so, maybe 200!
have you found the components window yet? this is a good way to keep track of the components in your model. you can also use it to add materials to specific components by
- insert a new copy of the component into the model, doesnt matter where
- add material to that new one. this will update all instances (copys) of it throughout the model
- delete the inserted component
repeat
Thanks. Still getting my head round the nitty gritty. Thomthom's simple suggestion achieved what I wanted to do - add materials according to layer - by using the colour by layer option. But that's a great tip - my drawings is mainly organised into layers, but supposedly by this way I could have more control if needed and change individual components on the same layer. Thanks for your help.
