Animator problems

I must be doing something wrong but what?



For the past couple of days I have been trying to animate the operation of a machine for a sales agent meeting with no success. There are 9 motions to animate with a real time operation of 20 seconds. I can set up the path of any one of them and it operates flawlessly. However I can not get them to operate simultaneously. The animation always stops when 4 movements are required at the same time. After that point the movements become intermittent and jump several steps at a time. Some movements are dependent on others. For instance a Z axis on the end of a Y axis mounted on an x axis slide. Others are pendulum style. I have simplified the assemblies as much as possible, and even tried saving assemblies as parts to cut down on the calculation time required. I have increased the time span to allow more time to calculate and still no go. The computer is a pentium 4 3.2ghz with 2 gig ram. The model uses about 500 meg when loaded. Is there a limit on animation movements? Any tips. I need all the help I can get. SW 2004 sp 4.1

I've noticed problems with flexible sub assemblies. They give that jerky motion you decribed. You can try dissolving them maybe?

Also, if there are any mates limiting freedom, they will cause parts to move unpredictably. It sounds like there is in your model.

It's those kinds of problems that made me look into equation driven animations (no paths). It's more of a pain to set up, but it's amazingly robust and the animations look fantastic when done.

I'v allways suppressed all mates afted I'v defined the animator paths. Important thing is to also define the "static" paths of parts...

One important thing, when you suppress all mates before animating, is to fully "define" the assembly with animator. So that in no animation step, there are "undefined" parts with no path, also remember the static path defining. This is how I'v managed to get some complex animations, with referring parts to work perfectly.
