Hallo,

best way? I want to draw  dams  in an drainage stream system ,  they
have to have especial withs and heights. How to construct the streams
the best way?Than I want to calculate the amount of material what is to
move there to build the dams from natural material of that area. 
Possible to export as .dxf and work in qcad?
