I'm working in C3D 2015 on a >300-mile pipeline project which spans from one coordinate system into the next. I need to stitch together GEOMAP captures for a key map sheet.
The Bing imagery looks great in both coordinate systems. I can't figure out how to re-project or reference or query one coordinate system's GEOMAP image into the other coordinate system's dwg file is such a way that the imagery appears contiguous.
Ideas?
Solved! Go to Solution.
You can use raster design if you have it available to you.... check out the following threads

Hope that helps
kudos are always welcome
This might be helpful...it discusses how to create a world file manually

Unless you have GIS there's no 'easy' workaround that I'm aware of.....
As an alternate suggestion, there should be free geo-referenced images available through USGS or other agencies (if you're in the USA) that may have a continuous geo-referenced image
Hmmmm...
J,
You could create a custom map projection that includes the entire project: Transverse Mercator for north-south, Lambert for east-west, or Oblique for any other direction. Drawings from both coordinate systems can easily be brought into the new coordinate system.

I fear you won't achieve your goal in a Cad environment, sir.
You need some Gis software, e.g. the free Qgis.
J,
Another possibility, from the Apps Store:

Excellent! I created a custom coordinate system from an existing coordinate system, and extended the westerly longitude parameter to suit my needs. The GEOMAP image then covered the two standard coordinate systems; the BING imagery slipped right into place.
The solution (thanks PD!) is very quick and easy.
Thanks a million for the crew's many responses and ideas!
