How to associate two or more bodies

[tanger1945]

Good afternoon,

 I am sort of new to CAD design and I want to learn how to associate two or more bodies when designing assemblies. My goal would be able to make a change on one part and have the related surfaces or sizes change on the mating or joined part. Think of tool making, if I change the size of the outside of the mold base, I would want all the plates to change, not just one. How do I set that up? Is it even possible?

Yes, this is what history-based parametric modeling in Fusion is all about.

There are several different approaches.

Have you started on a project? (Start with something simple.)

Hello,

 I do have a project that I have drawn up, it's basically a box with a lid. I want to be able to adjust size and have the change affect both parts. Thank you for the help.

Attached you will find your box and lid which I have joined together parameters.  You will only need to change three parameters as show in the Screen Capture below.  I also added a Slider Joint to the lid so you can open and close it to a maximum of 3".

If you have questions, please ask.  I had to modify your modeling order to make it a bit easier.  The main thing was to move your fillets and chamfers to the end of the design which is good practice UNLESS they are part of the modeling process.
