I've imported a clockwork motor that I created earlier but am stuck as to how I create a joint to fix it into the middle of this slot together crocodile model. Please can you advise the best way forward? Thanks! File attached below.
For
How do I joint this imported part?
Accepted solution
You want to add a sketch point to the CASE component of the motor to match up to a known point in the main assembly. You will see my choice in the Screencast. Since you have a linked component, you will add the point either by editing in place or opening up the motor. No matter which way, make sure you activate the component you are adding the sketch point. Activate the top level assembly and use a Rigid Joint between this point and your chosen point in the top level assembly. Model is attached but remember, I broke the link to make it a F3D file.

I know you are not there yet and I am making an assumption you may need a hint on getting the spring motor drive arm to slider component joint in place, I created one, outside your model to help you along. Please do not look at it unless you need the help, try it on your own but you will have it just in case.

You are absolutely correct John! I'll have a go myself and see if I can work it out for myself...
Meanwhile, a couple of extra questions..
I notice you have colour coded the components in the list on the left. How do you do that?
Secondly, I'm making the head from three vertical slices
I've used a head component with a single sketch for all three sub-components but I'm not sure if that is best practice, for example, I changed my mind about the circular hole in the head side, I deleted it from the sketch which deleted it from only one of the head sides. Also, for the new horizontal slot, I used a cut from the sketch to cut all three parts at once but suspect that I have moved one part slightly causing it to be misaligned. What would be best practice for such a construction. Thanks again for all your help!
I wanted to answer your last two questions by creating a Screencast showing you my personal workflow that I use repeatedly. I will not try an summarize it in words but let the Screencast do it for me. The model I used is attached for your trial if desired. At the last of the Screencast I show why I have colors on both my Browser and my timeline.

Hi John,
With your help, I have constructed and jointed the croc head and fitted the slider into place but I'm afraid I can't work out how to link the crank and and how to drive the jaw open. Please can you help?
best wishes

Rob,
I am sending my first Screencast along which shows you how to add the drive connection between the wind-up motor and the slide plate. At the end I point out the problem with your planned connection between the head and the slider plate. I decided to send this one along and I would do another after I scratch my head a bit on a workable solution, if I can find one that is. As I mentioned the Screencast is long as I had to modify the slide plate a bit. I will also attach the model, up to this point, so you can reference it if needed.

After thinking about it for awhile, the only answer is another Pin-Slot joint to make the jaw move when the slider plate moves. A contact set between the jaw and the slider would work in any other good CAD application but Fusion 360 just cannot handle it. The model needs to be cleaned up a bit, for instance the jaw had not been trimmed and goes through the slider, but you can see my concept from this Screencast and model. If you want to go this route, I will go a Screencast on the process if you cannot understand the process from the model. It is exactly the same process as I showed in the first Screencast. Let me hear back from you on this for no other reason just to let me know you liked what I did.

A lot of users swear by DXFer to export all components to DXF files. You will find it mentioned in this thread, message 3.
