Hi @Andres-Felipe_Gonzalez-Gil
<<...is it possible to see the coordinate system properties form the dwg file?>>
Yes. It's possible. You can enter MAPCSASSIGN on the command line. For example, if your site is in Berlin AND the original author has assigned UTM84-13N, then you'll get this after entering MAPCSASSIGN:
1. Your site is in Berlin and the author assigned UTM-33N.
If the author did NOT assign a coordinate system then MAPCSASSIGN will look different. It will look like this.
2. The author did NOT assign a coordinate system.
If there's no assigned coordinate system assigned, you'll need to investigate. Two reasons why you need to investigate.
- You'll need to (1) move, (2) scale, and (3) rotate the line work so it's properly georeferenced. May have to do all 3 or just a combination of two of them. Or do just one. If the original author did not draw in a geospatial environment, then you must assign a Coordinate System then move, scale, and rotate the line work to its proper location. OR......you may also use the method described below. (See steps a through e.)
- You'll need to turn on (or assign) a coordinate system to modelspace. It might already be drawn with a geospatial properties but someone has turned off or removed the assigned coordinate system. You'll need to turn on or re-assign the coordinate system so it can be returned to a drawing with geospatial properties. In this case you do NOT need to move, scale or rotate. You DO need to investigate which coordinate system the author used, then turn it back on. Determining which CS the author used might be (or might not be) easy.
To make your line work geospatial, you can do this:
- Open a clean, brand new metric template. Enter MAPCSASSIGN on command line=>In the Search Box enter UTM84-34N=>select UTM84-34N=>click Assign button. <<The coordinate system you search/choose may vary.>> Name this drawing New Map.dwg.
- Zoom-out until you see a red geomarker (it looks like a red bicycle wheel with red spokes).
- Go to Geolocation Tab=>Online Map Panel=>change Map Off to Map Hybrid (The Bing logo will appear in lower right corner of modelspace when you're connected to the Bing server.)
- Zoom-in on Bing aerial imagery. Pan and zoom to your site using the labels in Bing Hybrid as your guide.
- Cut-and-paste....CUT the line work from the original drawing then PASTE it into New Map.dwg.
3. Red geomarker and Bing logo.
New Map.dwg is properly georeferenced.
