Attachment is the vcmx format document.The bitmap shows Axial joint 1 and Axial joint 2 is separate.What can i do to join Axial joint 1 with Axial joint 2.RANDOMTESTS.vcmx (1.1 MB)

Hi,

You could try Mechanism Wizard to solve follower joint on this kind of closed loop system. Add-on can be found here:

Mechanism Wizard

Hi, Mechanism Wizard add-on helps you solve follower joints in systems that form a closed loop. Like the SasaHelper add-on (SasaHelper for modeling follower joints) Mechanism Wizard solves follower joint expressions with sasa-functions. The difference is that SasaHelper only measures the system but Mechanism Wizard tries to solve the follower expressions completely and write them into follower links. Mechanism Wizard doesn’t solve every type of system but usually you can model the system in a w…

I tested it on your model and it works if you first make rotational joints parallel. Mech wizard is little picky about that. Here’s a video on how I aligned joints and then used MW to solve followers:

Yeah,it works.Thank you very much!

I want to consult you another question.It doesn’t work this way.This approach does not apply.I have a Drag chain.Can you give me some advice?!
Drag chain is draged by the section one as the bitmap.

Mechanism wizard doesn’t work for the energy chain case. You could check out this add-on for the chain:

Energy Cable Wizard

Use the Energy Cable Wizard to create nice energy cables in your models. It comes with 2 modes, simple and detailed. The detailed mode still has work left to be perfect, but still looks really nice. When you have created your cable, you get a new tab with properties, where you can change the values of the cable even after it has been created, if you for example picked the wrong radius. Use the move tool set to hierarchy to move the whole cable to the correct place in the model. [image]   […

This solved my problem.Thank you very much.You’re really good!

I need to trouble you again.How to make the chain follow the gear?
