from dwg with cassini projection to shapefile with gauss-boaga

Someone can tell how can I find some tutorial to change my dwg file
with cassini pojection to gauss boaga?

thanks

 

If your using Autodesk map, you have to open a new drawing, save it as gauss
You add the source drawing, that i will call cassini.dwg to the group of
drawing
then attribuate à coord system to your drawings:
Gauss to gauss.dwg (your gauss projection: be sure to attribuate the
right one, there are many flavor ...)
Cassini to cassini.dwg
then you make a query: emplacement all, draw:
cassini.dwg as been transformed to gauss.
If projections don't exist, you can define it, but it an other problem ...

 

You can also specify the coordinate to convert to when exporting to
shape ...

 

Thanks a lot, I'll try this method with my friend that use Autodesk,
but I'm lookin' for some OpenSource GPL software.
