How to anchor a part in an assembly?

[devin_wolanick]

Hello,

I am designing the following:

The BLUE part is the control arm and I need the length between the sketch and PURPLE part to be variable for the moment. The length is being extruded from the sketch.

How to I connect the BLUE and PURPLE parts so that if I change the length the connection is static and everything on the right adjusts accordingly instead of the length extending past the connection?

Thank You

Normally you would Ground the component that you do not want to move and then use a Joint from it to the moveable component(s).  Adjust the Joint to place the components in relation to the Ground one.  This is dependent on how your structured your assembly so without it, there may be missing joints that get you in trouble.  If you want to post it, the Forum users can take a look and be exact.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Hi,

Simply position the part (component/assembly) via a rigid joint

Thank you,

I nearly have it working, the sub components do not move along with the control arm.

Should I be connecting every part with a joint like this?

As of now I just place them where they belong when I add them to the assembly.

Thank you for the help, I am new to CAD.

I have also attached a .f3z files as suggested.

Hi,

As a matter of principle, I do not load archive files (f3z) into my system because I run the risk of not being able to remove individual or several parts after editing, or only with difficulty.
You should first familiarise yourself with the different types of joints (rigid, revolute, slider...).
The aim is to create each assembly functionally with joints.

Thank you,

I will be studying how all the joints work in Fusion before proceeding any further.
This seems to be the gap in my knowledge that is causing my problems.

Conceptually, the ability to position components on insertion isn't there for the purpose of final placement (as evidenced by the fact that it's not a parametric placement.)  The reason that functionality exists is so you can put your component in our workspace in such a way that is easier to see where you need to apply a joint.  it's like spreading all your parts out on a table when you go to assemble them instead of having them all jumbled up on top of each other in a box.
