I'm dealing with CAD data in GIS, but I suppose it could be a Raster or anything else that may NOT have an assigned coordinate system.

1. When it comes to Georeferencing, is the Edit > Transform tool essentially the same thing as using the Georeferencing Control Points? Either way, when would you choose one approach over the other?

2. And, is using a World file conceptually the same thing (as above) only that the control points, and possibly the rotation, just entered as Text to follow rather that physically doing it yourself?
