Alibre has released a low-cost version of Alibre Design called Atom3D. Right now anyone can use it for 30 days at no cost and then pay the $200 license fee if they like it. It is a permanent license unlike most other CAD programs that expect you to pay a maintenance fee or the program quits. I've been using Alibre since 2005, mainly because I could learn it easily and afford it. I have no relationship right now with Alibre except for being a satisfied customer. I am discussing with them an opportunity to offer a six-month free trial of Atom3D for our subscribers as part of a long-term effort to discuss how to use Alibre to design an engine or a part for 3D printing. Nothing definite yet. I think Alibre is much easier to learn that Fusion360 or SolidWorks, both of which I have.
