Sometimes I do preserve the origin if it seems to help bring the raw DWG file into the SU workspace. It really just depends on the file I am sent-- sometimes they are way out in outer space, sometimes not.
I did find a workaround in the survey software I am using though.. If I import the DWG file, I can just create a point on the geometry of a known point that I know should line up with one of the imported points from the CSV file.. Once both sets of data are imported and misaligned, I can use an option to reposition one the imported points to the newly created one, thus aligning both of the data sets (point cloud and DWG geometry).
Thanks for you help. It does give me a clearer understanding of the origin point that I did not have before today. Ive been using this for surveying for quite some time, but this was the first time I was using actual GPS collected State Plane Coordinates in lieu of just creating all of them locally in SU. Ive been using a traditional Total station and or robot, but the introduction of new GNSS system threw me for a loop and forced me to explore areas of the software Ive never had to. Made my brain stretch.. Thanks again.
