How to contain an object within an object?

Hello there,

I am trying to create an arm that has a piece inside it that makes it extend longer. (Image Below) is it possible to only have the inner piece extend to a certain point so its not shooting out of the arm?


Any advice would be greatly appreciated!

If i understand you correctly, you could make the inner piece a child of the outer arm. So when you move the outer part, the inner part goes with it.

Thanks for responding Tim,

I don't think I explained it right, I tried to make another image. I'm just wondering if there is a way to set a limit for the inner piece of how far it can go.

Sorry, rereading your post, you explained it fine. It's my lack of caffeine currently inhibiting me.

You could use xpresso. What version of Cinema are you using? I can send you an example, just want to make sure I don't send a wrong version.

Lack of coffee is the worst! I'm using Cinema 4d Studio R14.

Agreed.

I forgot to ask if the main object will be staying still or moving?

I am creating a case that has an arm that folds out (which I just added a constraint tag so it only moves up and down) and coming out of that arm would be an inner arm that slides out. (the one shown in the picture) So it would most likely be moving

My apologies Aaron. I let this one slip down. I'll try to find the file I created when I get home much later this evening and post it for you.

No worries! Whenever you get the chance I'd appreciate it.

I'm away from my computer at the moment but I'm pretty sure that the constraint tag's clamp mode could do this for you. I think you'd want to make a null object that sits at the hole and clamp the extending object to it. You'd also need to constrain the movement of the object to a specific axis. There are a few ways to do that but clamp should allow it if you set your object axes up for it.
