I looking to start doing some home DIY projects. I'm looking for a simple, preferably free, program to help me design wood work schematics in 3D. For example I want to design a cat box/playhouse for the kitty cat.
This will also depend on if you are going to be printing lofts for cutting the wood.
If so then a home A4 printer will probably be too small and you will need to have these done at a printing company. Check what your local company accepts in terms of file formats and work back to the software from that point.
