It is very easy to use. It is also fast, intuitive and great interface usually people looking for. It is better than autoCAD,solid edge etc.

Nanocad is a free to use CAD tool that provides many features like intuitive interface, lightweight and supports dwg file format.

A remarkable improvement in terms of designs of structures and techniques, I love that this software is in a constant technological advance and every time there is a better change with more tools, it is easy to use thanks to its integration of lines and the API help you build automated tasks.
