going through the documentation but can't find any examples or explanation of how to read the whole dwg file
any idea where to find it?

Like I mentioned in the other post you just call CadReader.Read and you get a DxfModel out of it containing the whole AutoCAD drawing.

so

DxfModel model = null;
model = CadReader.Read(filename);
model.myEntity?

is enough to access all drawing data ?

Look at model.Entities in your debugger watch window.
