First create the part designs , and take that into assembly workbench and give constrain with help of mechanisam...and goto DMU KINEMATIC and click assembly constrain conversion -then mechanisam definition will come -then double click that and finally you will get mechanisam....

but it says, "Try to use 'Update positions' command because some joints are invalid (missing part or geometry)." But no missing part or geometry, i double checked everything in my project. I will be pleased, if anyone comes with a proper solution. Thank you.
