Layers and components ?
Is there a way to associate components to layers so when they are placed in a drawing they are automatically placed on the proper layer. Example: a frame assembly is associated with a "Frame" layer that has certain attributes. That frame assembly is part of a larger assembly and when that larger assembly is placed in a drawing the frame is automatically assigned to the Frame layer.
