I thought I'd try my hand designing some boards on the PC using some 3d programs. I downloaded the free version of Shape3d had heaps of fun making up lots of new boards. But I wasn't happy with some of the curves in the tail and the limitations of the free version I want to use another program to fine tune and work on the tail shapes, however when I tried to export them I found out I have to purchase the software which is fair enough, except as I'm just playing around at the moment $600 for 1 month is a bit too much for what I'm doing.
I had a play with AKUshaper but it has limited export options.
So then I had a look at Boardcad a free open source CAD/CAM-program. Website says it can open .s3d, .s3dx and .brd files. But it can't even see them on my PC let alone open them. Within Boardcad I click on open, go to the file my board shapes are in and the file is empty/blank.

Any people out there with some boardcad experience?
