Hi Barry.
Sorry for the lack of clarity. I will explain (hopefully) a little more clearly. I have several hundred files each containing three models; "3D-modell", "Drawing" and "Ritdef". The "3D-modell" model is referenced into the "Drawing" model. What I need to do is go through each of these "Drawing" models and (amongst other things) ensure that all of the levels for the reference attachment "3D-modell" are displayed. Sorry for the mixture of the English "Drawing" and Swedish "Modell".... I did not create these files..
I have a script which does the job nicely as long as I am working in the ActiveModelReference, but I want to automate this process to go through every dgn file in a number of sub-folders and perform the same action upon them.
I hope that makes it a bit clearer....
