Yes Viacad can save iges and step and acis, still early to say but at least for some one looking to start serious 3d modeling this is a very complete software for a good price i may even get one to use it as a translator for sat solids. send emails to the guy that wrote the sofwtare and ask him for demo they don't have a demo available (for viacad) yet,
