| May 13, 2013 at 10:04 | comment | added | Devdatta Tengshe | AFAIK, AutoCAD files never come with Spatial reference. What they come with, are coordinates. Each point, line and other objects are at a specific coordinate. Sometimes, these coordinates are defined with a local reference point, sometimes they are arbitrary, and sometimes, they might be in a specific projection/ spatial-reference. | |
