dwg
I don't have Autocad software and I can only find this free tool which can't read .dwg files.
Now, I need to convert .dwg to .pdf. But the teigha true view can't export .dwg
to .pdf. But I find it offers a plot command. Unfortunately, I aslo don't have the
DWF6 ePlot.pc3 printer. So, does anyone know how to handle that or is that an impossible
task? Do you know any other software can convert .dwg to .pdf?
There may or may not be projection information in the autocad drawing. If there is it can be read only with one of the GIS products from Autodesk (i.e. map3d, civil3d, mapguide).
You will need to either...
1. use an autodesk product to discover the assigned crs.
2. contact the originator and find out the crs.
3. convert to a format you can use (probably with no transformation), and then begin to discover the crs.
4. project the data with esri arcmap (which will create a world file for the dwg). [I don't normally use this method]
5. As Dano suggest rubbersheet (use a copy)
If you can send along the dwg or make it available for open online (autocad can open online dwg), I can take a look for you.
If there is an item in your dwg that is identifiable on the ground or another map, you can open the dwg with a free viewer (autodesk trueview), identify the coordinates at the known point and then begin to ascertain the correct prj.

I haven't tried any of these, but a simple Google search yielded these:
That last one looks like you need to upload the file to their server which may have issues if the file is big. It may have privacy implications.
