Joints from planes

Anonymous — Mon, 16 Nov 2015 12:48:49 GMT

I would find it very useful to be able to make joints between parts usng their planes.

I'm not sure what you mean here. Can you describe what you are looking to with more detail? Are you looking to join components at their faces or planes you created based on their faces?

Hi, It would be very useful if I could, for example, make a joint between an assembly right plane and the right plane of he base part. Or a joint between the origins, that kind of thing. Tim --

Hey @Anonymous,

You can achieve this by using the Joint Origin command from the Assemble dropdown. There's some more detailed info on this on our Learning site here:

Let us know if you have any more questions, and best of luck.

One of those links is no good and the other just points to a generic page.

You can put Joints between any snappable points on any COMPONENTS. Hint: Each Component's Origin is snappable. And you can offset those Joints.

Your tip is irrelevant and does not work anything like what the Author of this Post was asking for.

And your link doesn't work.

I know what you mean. I think you are a Solidworks or Inventor user too, right? Those are constraints. I think joints are a more powerful tool than constraints. You can fix, revolute, slide, etc. with one click. I think it depends on what you want to do, but once you learn to handle joints, it will be faster and easier. Maybe Fusion 360 can have both options like inventor does, constraints and joints. 🙂

The Joint Origin command does not allow planes to be selected.

A "workaround", which must be the most commonly used word on this forum, would be to create a sketch on the plane you want to constrain, make a point then generate a Joint Origin on this point. This adds some much needed unnecessary steps to your model, which is always nice.

I imagine this is difficult to implement as a function as Fusion 360 joints require a Joint Origin and planes are infinite, so where does the Origin go? If someone from the development team would like to "add it to a future development list" that would make me feel better.

If not with a sketched point, how do YOU answer the question, "If one wants to put a joint origin on a plane, how does one define the location on the plane?"

I don't see how the Reorient option allows for dimensioning the LOCATION of a joint on a plane.

Ah.... okay I got it.

But that's off the origin. Does it work on constructed planes in other places too? Or do you still have to project in or sketch a point first?

Re: Joints from planes

laughingcreek — Fri, 17 Jul 2020 18:30:06 GMT

You do need a point somewhere on the plane you want the joint origin to be on. the point can be anything. could be a sketch. could also be the vertex of a solid, or any of the implied points that show up when you are using joints (mid points along edges, cylinder centers, etc.)

I (capitalised because its the start of the sentence and for emphasis) would respond by stating that "a Joint Origin is a point and so must be defined as one, therefore you must use a sketch as Fusion 360 doesn't allow you to place a 3D point (that I know of)"

I'm going to assume what you really mean by your comment is "how would I (one) make a joint without a point?", which is what I was alluding to in my previous comment. This would require Fusion 360 to deal with its joints differently, it would need to recognise that a planar joint doesn't need a point, just two planes to align. Other CAD software can make joints (contacts/constraints or whatever they are called in that package) in this way, Fusion 360 cannot, so you are stuck having to use a point I'm afraid.

Fusion Joints need a point because they specifically define relative locations. The control sets available in other packages, like defining two planer surfaces as being parallel, don't do that.

By creating a new plane, you define it.

Re: Joints from planes

No...a PLANE, which is infinite in two dimensions, does not define a SPECIFIC POINT LOCATION.
