How to build a joint in these pliers?

[Anonymous]

Hi!

I've finished designing my pliers but I don't know how to do the joint that makes them useful. The image I've attached show my pliers. They are formed by three parts: two "arms" and a cilindre in the middle that binds the "arms" two together. I have already taken a picture but I need one with the pliers open and I need to describe the motion to open the arms.

Thanks

Hi,

Below are some screenshots that I hope are useful for you.  Select the respective inner cylindrical edges around which the arms will pivot and apply a revolute joint.

best regards,

Thanks for the answer. It works but I am experiencing a problem I can't fix. When the joint revolutes the two "arms" cross each other instead of stopping once they come face to face. It keeps revoluting when at some point it should stop

Hi jatrp,

Sanjay got you to creating the joint correctly and now you want to restrict the joints range of motion.  You need to set the joint limits.  

if you hover on the joint in the browser or right click on the joint you will see the edit joint limits option

Wit this option you can now set a minimum and maximum for the joints range of motion to eliminate the arms crossing over each other and more accurately represent your design intent.

hooe this helps.
