I’m in need of a CAD program with an easy aproach for someone with zero experience on this type of software.
3D printing is not a concern
I intend to draw the blueprints for my house. The building is old, no blueprints exist for it, and I intend to make renovations to it, so having blueprints to work on to plan the renovations will be a huge help.
for 2d your best bet would be qcad (free) and draftsight (paid). some distros have qcad in their repositories.
a little more sophisticated would be freecad with its bim workbench and blender with the bonsaibim addon. both of them let you draw in 3d and print floor plans off of those model.
for a quick mockup you can try sweethome3d.
