Loweiling: There are some known issues with Trimble and Civil 3D working together as one would expect. Dino Lustri, and Application Expert with IMAGINiT Technologies notes the following: 1. Make sure to install Trimble Link AFTER Trimble DataTransfer. If it wasn't you'll have to uninstall and reinstall. 2. Make sure the 3 locations for Metric Conversions are set correctly. A) Survey Database, B) DWG, C) the data collector. Dino mentions the faluire usually comes from converting the RAW/JOB/DC to FBK. Hope this helps.
