On a lot of my larger jobs, I like to keep my CAD database on the State Plane Grid. However, usually the legal description of the property that I am working on have their own bearing basis. I know that there is a way to scale the annotated dimensions to be ground distances. Is there a way to also annotate on an alternative bearing basis that would match the description or previous survey that I am working from?
Good question. It would be nice to keep the reference frame in state plane for surveying purposes, and then be able to keep the attorneys happy by being able to match previous basis of bearing systems to match previous deeds.
I'll be watching this one with interest.
Why not conduct the entire project in SPC to your satisfaction and archive that information for your own records.Then scale to ground (truncate your coordinates), rotate to your desired record bearing base and prepare your final drawings?
Yes, you can set up a user coordinate system unless you have the embedded version that runs on a piece of autocad. UCS is one of the commands that's not iucluded with the embedded.
Draw an east line rotated and based on your deed bearings, type UCS > entity, and select the line. I usually name my ucs so I can go back and forth between them as needed. Type UCS > WORLD to go back to grid.
Or at least that's one way to do it.
