The easiest way to get a flat area in a terrain maybe is to use booleans. Define a block (or whatever) and do the difference to the terrain. You should get a flat region there. Regarding importing architectural models. Well, i think it mostly is a question of testing. And maybe switching off the automatic centering and resizing for Vue in the preferences. I have good experiences with obj-files, but 3ds can work as well. The problem is, that these file-types are not totally strictly unified, therefore the output from different programs can be different when you mport them into Vue. Example. 3ds from Cinema always brings me an information window that the format is an old one and that the materials are not portated correctly. From Amorphium (f.e.) it is fine. Therefore test it with your program (AutoCad i think). hope that helps a little, Walther
