Matthew, thanks for the rsponse. Yes, 3ds files are import-able, but the layer names are unidentifiable in C4D - meaning you have to re-identify and re-name all the layers. .obj files actually work better. The "exchange" plugin from archiCAD eliminates this to a great degree saving lots of time, which is why I'd like to get it up and running.
I'm surprised no one in this forum has experienced similar difficulties. If there is a step or download that I'm missing, please, lend me your knowledge. Thanks.
