Hey guys, I'm having a problem figuring out how to constrain a valve/ valve seat mechanism. I don't know how to constrain the tapered surface to stop against the valve seat. :/



I have the valve move with a cylinder constraint. can't use a pin constraint, since the valve won't move then. I can't use a cam connection, since it won't let me select the tapered surface.



So I'm trying to get all these linkages to move together, and this is where I'm stuck.




and some eye candy :P :
