with inventor studio start a new animation and then in the animations of the various constraints set the constraints you want to animate. the program starts the animation from scratch and the split in seconds so you select your bond and the time in which you have to put us to perform that certain animation so then to overlap them all and create a unique one.it would be better to start inventor study with the together with the constraints you want to animate already defined and ready. and a little complicated at the beginning but then learn. If you need to ask.
