How do I find the coordinate system of a drawing? We frequently don't have access to the engineer/whomever created a drawing, so can't go that route, but need to know the coordinate system for converting into GIS. I have access to both ACAD and Civil 3D, if that makes a difference. Thanks!
Thanks for the response. "Geographiclocation" is literally the location of the area represented in the drawing -- lat/long, time zone. Unfortunately, it has nothing about the projection or coordinate system of the drawing.
I appreciate your thought, though.
In civil 3D, go to toolspace and settings tab for the current drawing.. you can right-click on the dwg and get the info through there.. see attached picture for clarification..
Are you looking to see how to see where the 0,0 origin is in the drawing?
If so you can draw a circle with an origin at 0,0 to see where the location is.
Or draw a line from where you can see, to 0,0 in some color that stands out -- the ZE
Try going to Format -> Units.
you have a few choices in the Angle drop down box. Are these what you are looking for? The active one is the one displayed in the Drop Box
There are a few other options in the dialogue box as well.
Thanks for the responses. The coordinate system I'm referring to is the projection -- was the drawing created in UMT, State Plane, etc, etc.
did you check my previous post about using Civil 3D? UTM info is located under the "zones" section in the drawing's settings... If your drawing was generated using info, that should have something showing there...
I did -- thank you! I was hoping there was a way within standard AutoCAD as well -- I generally use "AutoCAD Civil 3D as AutoCAD 2010", so helpful to not have to open/close multiple versions. But I'll take what I can get....
