I'm currently working on a project to make a metal part. I have designed a 2D plan and I was wondering if there was a software out there that would enable me to transform my 2D plan into a 3D model. This way I could have a better look to what I've designed.
I know Autocad has this capability, Alias I guess, and Solidworks will do the job but I'm looking for something simple and why not a free software that will be very simple to turn my 2D in 3D.
