I need help building a simple mechanical model with joints, body parts, and a hydraulic cylinder

I am trying to build this in altair:

This is what I have so far:

I am also struggling to incorporate the piston like in my hand drawing. Also for some reason this only works when I have 4 of the same joint, then a different joint, rather than using the sam

e type of joint for all of them. When I run this part it moves as it should be and then gets all deformed. If someone can correct me/send me aupdated model of what you would do it would really help. Thank!

Hi @Ironman123,

It looks like your actuator lower position is incorrect. The actuator is vertical instead of angled and is possibly deforming the links when extending. Please double-check the location of the hardpoints in the model.

Hope this helps!
