Cyber Blue used inventor studio a lot for the inventor award this year. Here are a couple of things I really like about studio.
1. The lighting styles make everything look really professional
2. The ability to animate faded parts/assemblies, awesome.
3. The ability to
conditionally suppress and unsuppress constraints in an animation

4. The ability to animate

Inventor Studio rocks!!
