learning blender

can anybody help me as i am wanting to use blender to polish up designs done in chief architects 3-D software? I have heard this is possible so if it is i could use the help.

There is a forum on this site called “Tutorials A collection of tutorials.” Perhaps that would be a place to start.

I see a dxf importer in blender. Is that what you are looking for? Export dxf and you need to enable the dxf importer file/ user preference/ addons.
I do not know if that is the best format. I did not see dwg. somebody else may know.
