LibreCAD: Installation, basic usage

I’m not good English, so this page translated by google.

LibreCAD

LibreCAD is an open source free CAD.
Those written in large DWG (AutoCAD) are heavy and difficult to use.
There seems to be no such thing as AutoCAD data to open comfortably

A new version has been released, but I still can’t open Dwg.
