I can confrim that the workaround bixlert posted is valid. I have been using this method for a few weeks now and has eliminated the headache of re-importing FBKs on larger jobs.
Although I completely agree with the above suggestion (seperate the control points...), I will toss out another one. Stop using FBK's files altogether. Personally, my life became much more pleasant after doing so
We like to use the FBK files as well, mainly for fixing errors (bad rod heights, etc.) and for bringing in traverses. Though the simplicity of bringing in a coordinate file is nice, for those of us that want to use the FBK import (and re-import) there's really no excuse for it not working the way it should.
I'm always curious how others bring in and manage their survey data. Do most people use Civil 3d exclusively with coord file and FBK file imports? Or another survey program for importing the points, traverse adjustments, etc? I've never been a big fan of Autodesk's traverse routines, but I've made work for me well enough over the years.
Thanks bixlert for posting the re-import workaround using multiple networks, I'll start using that method.
