Just found out some bad news...
X-CAD will contain Adware, and will cost $49 to "Remove" the ads, or even work offline.
Quote From Company Rep:
Yes, the banners will be there. The product works online. You will have an option to turn off ads and work offline if needed as well through a simple upgrade. Thanks.
From Their Website:
Alibre Design Xpress is 3D solid modeling software for the masses. It is better than low-cost, it's free! That's right, free. How do they do that? When you run Alibre Design Xpress some of your screen will be dedicated to ads that are served up by Google. They aren't huge and obtrusive but they might be somewhat distracting. After all, you're trying to model stuff, not shop. It's probably a reasonable trade off for the free capabilities. Alibre Design Xpress is a subset or scaled-down version of Alibre's standard software Alibre Design. As such, it has certain things turned off. This means there will be many things you cannot do. For instance, hollows or shells are disabled and you'll be limited in how many components you can have in an assembly. It also requires you to have an internet connection to use; that can be somewhat restricting if you are on the road a lot. But don't panic. Alibre Design Xpress has a multi-stepped upgrade path that will take care of the problem. For a mere $49, you can eliminate the ads and work offline.
I knew it was too good to be true. :Z
