I'm looking for a simple CAD tool for basic DIY projects.
The project I have in mind at the moment is a wall-to-wall bookshelf comprised of 40x35cm "boxes", made from 18mm MDF, laid out like bricks (ie each row offset 50% against the ones below/above it).
I want to get a feel for what it will look like, and want to be able to change things like the MDF sheet widths (eg what would it look like if the higher rows were made from 12mm MDF instead), box colours, etc.
3D would be great but non-essential.
I got some way mocking something up in Inkscape but it's not really the right tool for the job.
