You attach the DWG to a new drawing with a destination coordinate system assigned, and query in data from that original source drawing. Let’s attach some drawings. Hydrology and Streets. The current coordinate system, as you can see at the bottom of the screen, is UTM83-17, however, the hydrology is in Mercator, and the streets are in Lat/Long. Let’s just do a query. By double click on current query, I’ll just do location all, meaning bring everything in, and under query mode, I’ll choose draw. I hit execute, and even though the original drawings are in different coordinate systems, everything is now in UTM83-17, regardless of the original coordinate systems. To make this change permanent, what we would do is start a brand new drawing. We’ll set the coordinate system, in this case I’ll make it Lat/Long, so I’ve assigned a coordinate system to the blank drawing. This will not affect your course history, your reports, or your certificates of completion for this course.
