Comments about LibreCAD as a Alternative to Autodesk Inventor
This alternative is disputed. LibreCAD is still a legitimate Autodesk Inventor alternative, but it might have issues that some users think are important.
Inventor is for 3D CAD, LibreCAD is for 2D CAD.

Libre Cad is a weakly maintained fork of qCad. Even as 2D software I would not recommend it. It is not comparable with the amount of possibilities you have with the professional software by autodesk.

3d vs 2d. the end results of printed plans may not be too different but there's a large difference in use and also some different purposes for use.
