Ease of use, fast, intuitive, practical, POWERFUL, great interface, usually people are looking for a decent option to replace autocad; but NanoCAD is much better.
The free version is the best of all free CAD software, and the pro version is even better than the autocad itself, there is no important function in autocad that this software does not have.
Some minor problems, bugs or glitches aren't fixed until a new big update, there are some commands that I used to use in autocad that are not found or have different abbreviations
Stop looking for free CAD softwares, this is the best free option and the PRO version is much better than autocad.
I can do all my plans and designs at a very low cost compared with all its advantages, and if you are low in money, the free version is good enough to withstand.
