Animation makes no sense

Alec Seastrand Jan 15, 2017 7:45 AM

I have been trying for hours to get a basic motion study to function properly. I'm beginning to think this problem is a bug. I've compiled a number of videos over the past week, but a certain assembly with a simple gear mate is totally failing on the save function. It calculates fine, and it previews fine, but when I save the avi it freaks out. I tried different codecs to no avail. I've attached a *very watered down version of this assembly for reference. It uses tool box components that were made independent.

Alec,
I downloaded your file and got the same result. I see that your motion study does not have any mate to control the distance that the gear travels over time. I added a vertical plane at the start of the rack, then added a distance mate to the axis of the gear. In the motion study I set that distance to be 2.5" at start and 10" at end.

  Hello Bill,
  Wouldn't the original motor function at 6RPM control the distance over time? A distance mates between planes would have to override that. Or perhaps I just need the starting location more defined...
  thank you,
