Set latitude longitude of objects in drawings

[Anonymous]

I have a drawing with lots of circles on the map.

I want to extract the latitude and longitude of a circle, but the data extraction does not produce the latitude and longitude.

1. Is there a way to extract latitude and longitude, or is there another way?

2. Geographical Position-Marker Position-I've tried to add a marker to a circle with the function of points. Is there a way to make the position marker in the center of all the selected objects because there are so many places to mark?

3. When you insert the marker location and extract the data, there is an item called GeoLocation, but there is no information about latitude and longitude. Hover over the marker to see the latitude and longitude values ​​included. How is the latitude and longitude extracted from the data extraction?

If the file has been set using the absolute origin to create the drawing then the X and Y represent the Northing and easting (eg Long and Lat)

Check units to ensure your decimil point is correct.

You can use the 'eattext' command to extract the centre of the circles.

Hope this helps

You can consider modelspace to be a Map and the center points of your circles as locations on your Map identified by coordinates commonly referred to as  x,y. In AutoCAD the mapped coordinates are either feet or meters. Lat/Long, however, uses degrees, not feet nor meters. 

For you to ‘extract’ the lat/long from your circles, you must use Map 3D, Civil 3D or any other program equipped with geospatial functionality. 

The coordinates of your circles must first be georeferenced to a known projected coordinate system such as, but not limited to, State Plane Zone (feet) or UTM Zone (meters). Once your projected coordinates are established,

you may transform them to geographic coordinates such as lat/long (degrees). 

If you are using Vanilla Cad, you won’t be able to establish the coordinate system being used to identify your center points. Furthermore vanilla Cad doesn’t have the capability to transform from a projected CS to a geographic one.
