Separate CAD files into layers
The scenario: I received a microstation drawing (but could have been AutoCAD) with about 15 layers in it, each representing a particular highway route option the client wanted me to evaluate. To simplify my evaluation, I really needed each alignment on it's own GM layer so I could easily turn on and off. I did this manually by Search by Attribute... and sorting by layer (within the DGN) and then selecting all items in the same layer and manually pushing them on to a GM layer. Seems to me that this could be automated fairly simply with GM itself. Say, file in Overlay Control Center, and have a right-click option to "explode" to layers. This would essentially replicate the layer structure of the CAD drawing in GM Overlay Control. Quickly toss all the created layers into a group (love that feature by the way) and that would be very helpful.
