- [Instructor] Coordinate systems should be signed to all DWG files. Although non-geographic files, for example data inserted at 00, don't require a coordinate system. Most data used within the AutoCAD Map 3D tool set does require one. Now there are approximately 4,000 coordinate systems to choose from and you can even create your own. Let's assign one now to our Hydrology drawing. When you receive a drawing, you should know what coordinate system it is. Now if you don't know, you might be able to guess. For example, if you use the options, and choose coordinates, when you move your mouse around the map in the bottom corner of the screen, you can see the coordinates. Now in this case I see -80 and 43. I can kind of guess that's some sort of Latitude-Longitude Coordinate System. But I happen to know, or I was told, that this drawing is in Latitude-Longitude 84. Let's assign that. So under the Map Setup ribbon, under Coordinate System, click assign. We're going to search for coordinate…
