I'm doing a jib crane and i want to do a motion study where i move a weight trough the crane and stop it at the end of the crane. When i do the motion, my body keeps going past the point that i ordered it without colliding with another solid that i had placed at the end of the crane... Another coleague of mine is having the same problem and we can't seem to figure out why this isn't working... Do you guys have any tips or ideas on what could be going wrong? We have already defined contact between the two bodies, precise contact, and a linear motion. We also changed the integrator to WSTIFF.... Any help ?
