Creating a joint between two components.

Hi once again... you fellas are starting to become family 🙂

Did search the forum for an answer, but just wasen´t able to find what I was looking for, might be the language barrier -might be me being no good at searching. Nevertheless, could you please help me out?

Have a look at the screencast and please do educate me 😉

Is there a specific reason you want that to be a rigid joint?

It would depend on what you are looking to achieve in the end, but if the components don't move or they all move together I would not place a rigid joint there. Instead I'd move the parts to the right place and make a rigid group out of them. This fixes them in place (with respect to each other). Then any resulting joints of the group will force them to move in unison.

Hi @petrol_junkie,

You're very close! You just need to create the joint origin before you create your joint.

If the components won't be moving relative to one another, I personally recommend positioning your components where you want them with Move or Align, and then creating a Rigid Group rather than using rigid joints to position each one. 🙂

Hi @petrol_junkie

Thanks for reaching out! I think the issue here is that the two faces you are attempting to create the joint origin between are contained in separate components. Joints exist between two components, so when you try to create a joint origin referencing two separate components, Fusion will not let you select the second (or third total) component.

I've walked through this in the screencast below, but would actually recommend using your workaround of creating a sketch to position the joint origin rather than cutting bodies between components in your existing file, as this will give a more stable parametric solution than reorganizing the browser. @ryan.bales Move > Rigid Group option would be a good workflow to use as well.

I hope this helps! Please let me know if you have any questions.

EDIT: The triple post!

Hey there @petrol_junkie

Here's what I would do:

Split body in the patch environment so you get two bodies from your main body. Then Create>New component>From body and get a a new component from the newly created body

Then proceed with the method you mentioned in your screencast.

Hope this helps!

@kate.raskauskas

Thank you for your reply and your screencast....

The method you are showing is the one that I used, language barrier once again, I wasn´t good enough at explaining how I "solwed it".

But please be on the look out for more of my posts - because I´m bound for need of more help, that´s for sure 🙂

@Anonymous

Split body in a patch environment?

I´m designing a welded part, consisting of about 8 cut steel plates, as simple as that.

I dont want workarounds, just an easy way to align my plates 😉

Thank you for your reply.

Hi @ryan.bales

You did post a Screencast did you not, got an email regarding it, which explained it..... but for some reason it is not in the post.

Thoughts?

ryan.bales — Thu, 22 Mar 2018 20:03:29 GMT

I did not, @paul.clauss did one but his post got removed for some reason.

I basically said the same thing Kate did, Rigid Groups would be the way to go for me if the objects do not move or move together.

Here is my video:

Hi @petrol_junkie

Thanks for reaching out! I've included my original screencast and post below, just for further perspective on this issue. I think the workaround described by @ryan.bales and @kate.raskauskas is a great way to move forward - this may help describe why the workflow in your screencast was not working.

The issue here is that the two faces you are attempting to create the joint origin between are contained in separate components. Joints exist between two components, so when you try to create a joint origin referencing two separate components, Fusion will not let you select the second (or third total) component.

@paul.clauss thank you for clearing that up, know now how to work with joints a bit better. Since I use SW for 8 hours a day at work, I´m kinda in that mindset when I get home and start up F360...hehe 🙂

@ryan.bales to give you a bit of an answer to your first post....

I want the plate to be seated dead center between the other two, since the top plate is subject to dimensional changes, it will always be located in the center.

And I did not want to make a new component, derived from that position, since it would have been exactly the same as the other ones. When the parts are sent for plasma

cutting the BOM should be as clean as possible.

Making the whole welded piece out of bodies does not seem to be an option in F360 since you can´t make a BOM from bodies - only components.

A good tip here would be for the F360 dev.crew to take a peek at the Weldments functionality of SW... it is so much more than just tube profiles. 🙂

(Might make an inspirational video about for the Idea station in the near future.)

"Instead I'd move the parts to the right place and make a rigid group out of them."

This method, in my line of work, is an absolute no no.... placing parts without parametric input. Every part needs to be exactly where they´re intended to be no matter the changes

that might be made.

Thanks for answering my original question! That makes sense as to why you did it that way originally.
