HI friends, I have created an mechanism of two bodies using kineamtic type and using Planar constraint. BY setting servo motor and type as Kinematic in Analysis definition, if i run it, its going correctly in horizontal and vertical direction. But, if i use the type as Position in Analysis Definition, its rotating.. i need to solve this, because i need to take this mechanism in to Animation module.. whereas the animation module is accepting only the Position type... Please help me to fix this issue. Thanks, Balaji
