This won't be a deal breaker for most, however any Chief Architectect users will find v7 files will no longer open in C.A. X-1. Version 6 files will. A work around is to export as 3ds from v7 and import back into Chief with the 3ds file. (I realize this is not a Sketchup problem) Just a note to any Chief Architect X-1 users. I am hopeful for v7 and so far I like some of the new changes.

Kevin,
you can always save your SU 7 model in SU 6 format (just scroll down the pulldown on saving). This can always be a workaround with every 3rd party app until they update their importers.
