Linux

I have used Sketchup for more than 4 years, and after looking around for Alternatives to use on Linux, the only thing that can do the job is Blender, it's not just for animations and 3D printing, in fact blender can do anything you can imagine, if not by itself, then by the addition of addons

Out of the box, Blender doesn't behave like Sketchup, but it can do so by enabling some preinstalled addons ( like Archimech, Measure it, Precision Drawing Tools, Stored Views, Auto Mirror.. Etc ), also there are free and paid addons on the Blender Market

For modeling Blender is waaay more powerful than Sketchup ( but SU is much more simpler and I find myself using Addons - in SU - for the stuff I can do in Vanilla Blender directly )

For Printing: they both suck ( in a paper printing use case ), if you wanna print in Blender you'll need to export to a 3rd party program like Inkscape or LibreCAD, or use an addon

Sketchup printing is just painful, save a view, save the file, fire up Layout, import view, then print...like why ?!!
