Problem with KINEMATIC_ROTATE

[ FlexSim 21.2.1 ]

As you can see in the model attached here, the scissors stopped at about time 9s and kept still to the end. I'm wondering why should this situation happen? Shouldn't the scissors keep rotating till the end?

The angle at which the scissors rotate is determined by the degree_rot value in your model. The value of your degree_rot is 11.24, so the scissors will only rotate to this angle and stop.

The return value of the addkinematic() func is 8.2s, then why would the whole rotation process stop earlier?

addkinematic() returns the model time at which the kinematic will finish, not the duration.

Oh, right!

Then i wonder why the model still running as the kinematic already finished?

I set a breakpoint at BasicTE1's "On Finish Offset" trigger, and found that the breakpoint was triggered at the ending time 11.62s. This means the Offset is not sync with kinemaitc?

While addkinematic() returns the finish time, the expected return value of the "On Begin Offset" trigger is in fact the duration of the action.

To sync the "On Offset Finish" event with the end of the kinematic you should return "Math.max(time1, time2) - Model.time" in the begin trigger.
