kinematics plane change location

hi

i creat a model ,which used kinematics pf ,which is applied to item rotate, however,after finish kinematics,the contained palne just changed the position,What did i miss ? Two pics below,one is before run,the other is after. Hope these can illustrate my issue.

thank you

@Paragon.liu It would be so much easier if you just added the model to this post.

Here's the example: KinItemRotateOnConveyor.fsm

At first glance it looks like a bug - we'll investigate.

Maybe it is a bug, do you have a way to circumvent it ?

Not yet - I've sent it to the developers for consideration.

The easiest way to accomplish what you want is to use the pickoptions for the decision point. It is difficult to use the kinematics activities in process flow in this case because the item already has kinematics from the conveyor. There is a pickoption to rotate the item. There is also a pickoption to stop and delay the item. By using both these pickoptions, and specifying the same time for both operations, you can achieve what you want:

kinitemrotateonconveyor_1.fsm

Also, if you need to configure many Decision Points with this logic, you can either use Object Templates or Property Tables.

The reason the plane rotates is because the Finish Kinematics activity is finishing kinematics for all 3D objects. Usually, you'll want to finish the kinematics just for the item you are trying to work with. In your case, you'd want to specify token.item.
