Hi All,

I am trying to animate a marker block to go around a rubber belt.

to show that the belt is running as well as the pulleys.

No matter what parameters that I use, it fails and I constantly receive this message.

Motion analysis messages

Failure to satisfy velocity initial conditions.

A probable cause is an over-specification of initial velocities of bodies.

Please specify fewer initial velocities and try again.

What the hell does that meaningless text actually mean ?

What is it trying to tell me ?

I have tried setting the velocity as low as 1mm/sec and still have this message.

Do I make the belt sketch ..... a path, or a spline, or both ?

I have tried them all.
