Jointing two assemblies

[colin.watters]

I have successfully joined two components together in F360 but is there a way to join two Assemblies in one go?

When I try it seems to strip a components out of one Assembly and join it to the other Assembly but it leaves the rest of the previously jointed parts behind. 

Is that intended behaviour? Can you only grow an assembly one component at a time or can you join two complete Assemblies in one go?

Thanks.

the usual technique here is to fully constrain your sub-assemblies with a set of joints (could be rigid, or could include motion joints, but the important part is that all components have joint relationships to the rest of the components in that sub-assembly.  Then, all you need is a joint between two components in each sub-assembly to connect everything up.

Very often, when you are placing Joints between components or between sub-assemblies, in the Joint Preview it would seem the wrong component is moving and disconnecting from a previous joined assembly.  Do not let this deter you, go ahead and commit the new Joint and the rest will follow back into position.  In the Screencast I try and show this behavior.

I suggest you share your assembly here.

If you have a personal subscription, then export the design as a .f3z file and attach it to the next post.

Thanks for the replies. So it should work, must be something i'm doing wrong. I was cancelling the joint when I saw other bits left behind so that was probably it . Unfortunately I've got to travel for a few days but will try again when I get back. Thanks again.

Just a thankyou to @jhackney1972 .  Seems I just needed the confidence to hit OK and F360 sorted it all out.

I am trying the same where I have created "rigid groups" of the assemblies and then trying to introduce a Revolute joint between the two assys but I don't get it to work.
Do you really need to "rigid joint" all parts in the assy instead of using the rigid group?

After I have selected the two assys (in as-built joint) and also the snap point my whole designs becomes wire frame and in the animation nothing but the flag for the joint is moving.

After clicking OK, if I try to move the "rotating assembly" it just seems rigidly jointed to the the other assembly.

Please attach your model so the Forum users can take a look.  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. If needed, ZIP a F3Z file.
