Co-ordination Prob

AS THE TITLE SAYS..I HAVE PROBLEM RELATED TO CO-ORDINATION...IF I GET THE LATITUDE AND LONGITUDE FROM GOOGLE EARTH..HOW DO I INPUT IN AUTO-CAD...AND SOMEONE HAS ANY IDEA ABOUT BENCHMARK..LIKE THERE IS TWO POINTS IN AUTOCAD DRAWING..WHAT IS THE USE OF IT..IS THERE ANY PERSON KIND ENOUGH TO HELP ME OUT AS SOON AS POSSIBLE..thanks in advance..(plz..if u have links related to co-ordination..do specify..and explain briefly please)thanks again..hoping for earliest reply..

The best way forward is to get coordinates from Google Earth in UTM metres instead of Latitude and Longitude.

I am afraid that I did not understand the rest of your post

you can add a pushpin to get lat long coordinates...

i think the rest of your post needs a surveyor. benchmarks are used so design teams and construction teams are on the same elevation.

eldon... thanksalot for helping..

and ems too..

at first i did not know..what is utm..then later i googled it..when i saw the full form..i understood..hehe..so now i am prepared..can u just help me last time plz..becoz i could not find in google..after getting the distance from google earth..it will like 435455.448e 3443544.338n and 343545.433e 4234343.554n(of two coordinates)..then i gave a command for line then i inserted the first number(east)..then second one(north) and again for second coordinate..i did the same thing..finally i got one line...

now i checked the total distance of two coordinates..but it is showing different in autocad..and different metres in google earth...my question is so can u or anyone say the way to measure the distance between two coordinates in autocad..thanks

The easiest way to get the distance between two coordinates in AutoCAD is to draw a line as you have. Then you can list the line.

You say that this distance (796 km) is not what you had expected. What distance were you expecting? If you are measuring distances of this length, have you allowed for the curvature of the Earth? Are the coordinates in the same UTM zone? Perhaps if you can give a brief account of what you are trying to achieve, then you could be given meaningful advice.

There are web sites which will calculate distances between points in Lat and Long. Great Circle distances.

eldon....i will explain u in short..i have two utm co-ordinates..ok..how do i input that two coordinates to autocad??that is my question.please explain in brief or provide me the link for the that..because..in coordination part..i am new..as i moved the profession from engineer drawings to civil drawings..thanks..i hope u understood my question and waiting for the earliest reply..

and my zone is 37r how do i fix that zone in autocad??

If you look at the Home page of CadTutor, in the left hand column, there is a link to the tutorials. By reading these, particularly Drawing Objects, it will be explained far better than I could.

Your other query about fixing a zone in AutoCAD, I think that you need to be running some Civil or Mapping version, or you need to GeoReference the drawing. I don't know how this is done, but I expect someone else does

anyways eldon thanks for the help..
