Topo points dwg => solidworks

Hi all

I receive complete topographical surveys in . DWG for my work. (They are well in 3D years Drafsight)

And I'd like to import these points directly into SolidWorks to make a 3D plan of a terrain.

How can I do it as quickly as possible?

In my opinion, the best would be to be able to export all the positions + altimetry of these points and put them in a .txt or Excel

But I don't know how to do it...

Can you help me or give me your technique if I miss something^^

Thank you very much:D
