Hier noch ein paar Info's dazu:
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. You can also upgrade to the full Alibre Design software. Standalone, the standard verion of Alibre Design software costs less than a grand so it's pretty inexpensive for 3D solid modeling software. They also have Alibre Design Professional and Alibre Design Expert. You can visit their web site for details on those packages.
