Sweethome 3d looks interesting, thanks for posting…
Anything open source/cross platform (ie available for Linux) for garden landscaping? I just want to play around placing walls, benches, borders, shrubs, climbing frame, sheds to get an idea of how it might work. Will Sweethome 3D allow me to do that?
EDIT: found a tutorial for exactly that: http://www.sweethome3d.com/blog/2017/06/21/how_to_design_a_beautiful_garden.html
I attempted to run Sketchup in a VM but lack of hardware gfx acceleration put a stop to that.
For Noddy 2D stuff I quite like LibreCAD
I have very little experience using CAD, but I got on with FreeCAD. Have used QCad for 2D stuff in the past.
