I asked to make simulation for my project on Solidworks course at the university.
I have made the assembly and all works great. Now I started to make the animation.
One of the parts needs to move along path in 2 seconds.
I have set the path mate to 0% at 0 sec. then moved to 2 sec and changed the path mate to 100%.
The part is moving as expected, but the movement is not constant along time. some time it stops, and then continue.
I attached screen shot to explain better.
