Hello all. First time poster here. Had a question in regards to converting between UTM and State Plane Coordinates. I was provided CAD files that are "supposed to be in UTM". No published coordinates of course, just contours and a tin. They asked if I could change the CAD files from a UTM meters drawing to State Plane Coordinates US Survey foot drawing. The only way I could think to accomplish this would be to figure out a lat and long for a couple of points in the UTM drawing and convert those few points to State Plane with TBC and go from there. Has anyone ever done this before? If so how about other ideas. This is simply a drafting exercise no field survey performed on our part. I actually have multiple drawings in different coordinates systems they are trying to convert to one system for ease in drafting. Hopefully there will be common points in each of the drawings I can match up.
Thanks for any input.

If you have TBC it's simple, set up a file with UTM and meters, import your UTM coordinates, then change the file's coordinate system to the state coordinate system you wish in US survey feet. 🙂
Thank you sir. That's what I thought was the simplest way to handle it as well.

It would be a big presumption to assume "they" have any clue what they are working with. This could also be easily converted in the CAD settings for the drawing.
