Are you drawing in Georgia East Zone?
If you are, do this:
- In modelspace of Map 3D, assign an appropriate Georgia State Plane and Zone, examples include, but not limited to, are GA83-EF (EPSG 2239), NSRS07.GA-EF (EPSG 3519), NSRS11.GA-EF (EPSG 6554) or whatever Projected coordinate system is appropriate to your site location. Don't assign a Geographic coordinate system. (Projected will use units of feet or meters while Geographic will use unit of degrees, such as Lat/Long).
- In Google Earth Pro, highlight the points shown in the Places Panel on the left. Right click and choose 'Save Place As....' then save the points in a dedicated folder using 'kml' or 'kmz' as the extension.
- Back in Map 3D, Planning & Analysis WS, Insert tab=>Import panel=>Click Map Import icon. 'Change Files of type' to Google KML and browse to your Point Folder. Import the points. If you have multiples use Shift+click or Shift+Alt so you don't have to import them individually.
- Next, in the Input column, un-check ALL rows with the exception of PLACEMARK (a Placemark is the GE Pro term for point). Notice the Input Coordinate System column, it shows LL84, the coordinate system used by GE Pro. Leave LL84 as-is, if you change it you'll have issues, big time. While still on the Placemark Row, notice the Points column. It displays the default object <ACAD_POINT> which will be used to represent your point. You should enter PTYPE on command line after the Import procedure so you can change the point style for better visibility, otherwise you're limited to a mere tiny dot.

You have chosen Georgia State Plane West zone, Meters (not feet). Are you absolutely sure you want west zone and not east? Caution, if you guess wrong, you'll have issues.
What is the lat/long for the 'center, of your site? Go to Google Earth Pro and get the Lat/long then upload the coordinates so the correct State Plane and Zone can be determined. When it comes to selecting the correct CS, close doesn't count, it must be spot on.

Your site is in Gwinnett County which is in Georgia West Zone. Start from a clean, brand new Imperial template. Then do this:
- On command line enter, MAPCSASSIGN. Then in Search Box, enter Georgia. From the results of the search, select Georgia NAD83, West Zone, US feet, or GA83-WF EPSG 2240. Click ASSIGN. Refer to image below.
- MAPIMPORT command and import the kml file you made using Google Earth Pro. In the Input column, place check on only on the row named PLACEMARK. All other rows must be un-checked. Keep all other columns at their default values. click OK.
- Enter PTYPE on command line. Change from the default 'dot' point style to one of the other styles such as one that uses a 'square' or 'circle' in the style.
- Turn on Bing Aerial imagery.

You are using the WRONG coordinate system in modelspace.
The correct one is GA83-WF
GA=Georgia State Plane
83=North American Datum (NAD)
W=West Zone
F=US Feet
You are using GA83-W
Someone took the F out? Gotta leave the F in.
If you are using a State Plane and Zone without the F at the end, then you are defaulting to meters.

Of course it can understand lat/long from Google Earth Pro and put them into a dwg which uses State Plane. Upload your kml points or a sample of those points. Solving this is not hard at all.
This is not a GE Pro-to-dwg issue. This is understanding how coordinate geometry works issue.

From what you are describing, it sounds like you are having an issue with importing a point created in GE Pro which uses Lat/Long Coordinates (LL84 referenced to WGS84). Here's a screencast that demonstrates how to import your kml point that was created in GE Pro (it has the same Lat/Long as the point you mentioned in post 14 of this thread).
Things to consider before you try to duplicate this exercise.
- Start from a brand new, clean IMPERIAL template being extra careful not to use metric.
- Use the correct State Plane coordinate System, GA83-WF, EPSG 2240. Don't use GA83-W, EPSG 26967 because that one is metric.
- To establish the CoordSys in modelspace use MAPCSASSIGN command.
- Do not ignore #3. You may have used other commands in the past or have used recommendations by others to set your CS. Those other commands, although accurate, are tricky to use and even more difficult to explain in a thread on a forum.
Once you have opened a brand new, clean imperial template and have assigned your CS, you can view the video.

Based on your uploaded images, using one of those coordinate systems will give you 'grid coordinates' in units of meters. (If you use PAK-I/a or PAK-II/a then your coordinates will be in Indian Yards, and whatever that is I don't know--refer to image named auto.jpg in Post #16.)
When you draw in Modelspace, you can use various units such as, but not limited to, millimeters, meters, inches, feet. This means when your drawing units are in meters and want to draw a circle with radius 3 meters, you would use the circle command and enter '3' for the radius. If your circle needed to be 7.25 meters, then you would enter '7.25' for radius. However, if your circle needs to be 500mm, then you would enter '0.5' for radius because 500mm is equal to one-half or 0.5 meter. If you accidentally enter 500 for the radius, then your circle would have a radius of 500 meters, not 500mm.
If you have to work in feet using a coordinate system that uses meters, you will need to convert all your feet numbers into meters. This means you will have to convert all your imperial measurements to metric. You will need to gather all your imperial measurements, put them in a spreadsheet then convert them using formulas: one formula for distance, another formula for area, etc. etc. Once you have converted all measurements, then you can efficiently draw using a Pakistani coordinate system.
Why must you convert the numbers? Because the drawing units in modelspace will inherit or adopt the units of the 'Assigned Coordinate System.' Since there is no out-of-the-box coordinate system for Pakistan that uses feet, you are relegated to using one that uses meters.
Only the United States still uses feet, all other countries use meters or have already switched from the King's Foot to metric. Yes, we are stubborn and like to go our own way.
One final note, your uploaded image named auto.jpg3.jpg indicates you have highlighted UTM84-42S. Do not use that coordinate system! If you want to use UTM coordinates, use UTM84-42N instead. The 'S' indicates a zone south of the equator while 'N' indicates a zone north of the equator. Since Pakistan is northern hemisphere, you will want to use UTM84-42N.

I'm trying to import a .kml into AutoCAD Map 3D 2022 but there is one problem. I have the klm file with all the information and I want to import it to autocad to edit the information. The only problem comes when I have to choose a Coordinate system. I dont know wich system Google earth export it.
what should I do to select in autocad the coordinate system, which from Google Earth pro as klm has been exported?
Data in Google Earth in WGS84.
In Map 3D, the corresponding code is LL84.
But you can choose another coordinate system, whichever you prefer.
For example, metric, foot. Or so on. MAPIMPORT will convert from WGS84 to the assigned coordinate system
.
are you saying I shouldnt select in Autocad Maps 3D the coordinate system? because I searched the one you meaned (LL84) and also I got more than a coordinate. Do you know where do I find more information about coordinate system between Google Earth pro and Autocad Maps 3D?
