Another Ball Joint question

Another Ball Joint question

Another Ball Joint question

(OP)
I constructed a simple ball joint and used a concentric mate to the two spherical faces. This works fine and gives me full 360 deg rotation, but the ball has a shaft sticking out of one side. How can I limit the mate so the movement of the ball and shaft in any rotational direction will stop when the shaft comes in contct with edge of the female ball joint

Depending on your SW version you should be able to use the Limit Mate function.

CBL, I dont understand how a limit mate can be applied. This ball joint is similar to a joy-stick controler. If I jam the stick in any position, it will only go so far because the stick hits the housing for the ball joint. How can I apply a limit mate that is looking for an angle or distance limit? Or maybe I just dont understand the full functionality of limit mates

CBL, YouDaMan...Thanks, I would have never guessed this mate combination for this movement.
This Forum is great...

Depending on what you need to use the assembly for, you could also use collision detection in the 'move component' menu.  Be sure and check 'stop at collision'.

thanks for the tip. I tried this and it works great. But can you turn on collision detection from a system level so its just always on if you want to?. It would also be cool if you could select geometry as a boundary option rather than entering a distance or angle for limit mates. In my case a concentric mate is good for the movement of the ball joint, but it would of been cool to just select geometry (edge or face) to establish the limits of movement. this would be similar to collision detection..
