I have a problem to create Shape files.
I hope some one can assist me.

I have a map in Autocad Format.
I can overlay this map on Google earth exactly and i can find right Lang/Lat.

But i dont know how can i convert this autocad file to a shape file?
I have made some shape file by some various softwares like Cad2Shape,
But final shape file does not have any Lang/Lat information!

How can i spesify projection of a dxf file in autocad?
How can i make a shape file with Lang/Lat information?

I download a sample Shape file from internet and that contains Lang/Lat information,
but i dont know how can i make a similar Shape file.

Where is my mistake and what is right way?
