Is it possible to import a cad file as a background map? Sometimes, really most of the time I just want to see the lines. One thing I try to do on each job is load up a drawing and walk thru with my reciever in hand and check over my survey drawing and what not. Quality Control. Some of these jobs have a lot going on. Some jobs are construction staking jobs. Construction jobs are a little different, there is a need to stake a line from the drawing, say a contour line or back curb, whatever it is, for rough grading. When the job progresses most all the stake out points are computed in the office and reviewed before staking, so at this point I only need to see the lines again. So a background type map would work. And sometimes I dont want my crew to be able to select any linework. Depends on who it is. A newbie, nope. My top hand, yes. The LS spends a lot of time loading objects that I will never need. Just some thoughts.
