addkinematic travel timing in the processflow is not matching the 3d objects

for instance In process flow it shows 30sec to do the particular kinematic movement(rotation or travel) but in 3d object it takes less than that, help me to figure the mistake which I have made.

thanks in advance

The addkinematic() command "returns the time that this kinematic operation will finish." (https://docs.flexsim.com/en/19.1/Reference/DeveloperAdvancedUser/Kinematics/#addkinematic)

You need to subtract time() from your label assignments in order to get the amount of time that the kinematic will take rather than the end time of the kinematic.

double rotate2 = addkinematic(label(toolArm, "arm"), 90, 0, 0,20,0,0,0,0,time(),KINEMATIC_ROTATE);
token.labels.assert("rotationTime2").value = rotate2 - time();

@Kishan Jayakumar The addkinematic function returns the endtime of the kinematic and not the time it takes to perform the kinematic. So in your case you should always subtract time() from it. By the way you don't have to use the labels.assert if you just deal with the value of the label. Just token.labelname is enough.

So for instance in Fixturerotation, the last line should read:

token.FixtureRotationTime = FixtureRotation - time();
