Parallel Face Joint between Components in Assembly

kjav — Sat, 31 Aug 2019 15:21:12 GMT

Hello. I came from SW a while back. I used parallel mates extensively in SW, but have struggled to do the same thing in Fusion.

I have 2 components in an assembly. I want a face on each component to be parallel to each other, but the two components don't touch each other, and the two components/faces are at a variable distance from each other.

This can be done with slider/planer joints, however, I cannot figure a way to do this without *also* locking in the distance between the parallel faces, which I don't want to do at this point. Just want them parallel.

For example, I can make the two faces a slider or planer, but then they slide directly against each other, making them co-planer, not parallel.

The other option is to define a joint origin some distance away from a face, or "between two faces", but that will cause the two planes to be locked to a specific distance from each other, which I don't want.

I basically want something like the Fusion "Align" command but make it sticky.

Any suggestions much appreciated. Thanks in advance.

I would have thought the Offset dimension in the dialogue box will do that.

Might help...

The offset dimension I believe needs to be specified, which goes back to the original problem that it would lock the two faces a specific distance. I don't want to offset it to a specific value, as I want the part to float for now. I'm looking for a purely parallel constraint with no limitation on other movement.

This isn't really the answer, because it's a convoluted workaround. But you can achieve the behavior your describing like this-

-add a new component, which becomes an assembly in the next step (the helper assembly).

-to teh "helper assembly" add 2 more components (they can be copies of each other) called helper 1 and helper 1

-helper 1 and helper 2 get joined with a slider joint.

-helper 1 and component 1 get joined with a planer joint

-helper 2 and competent 2 get joined with a planer joint

attached is an example. I put a sketch in the helper components to make it easier to see what's happening, but you don't actually need any geometry at all to make this work.

Thanks for the suggestions. I've found another way to work around the problem for now.

I found a link to this video in another discussion, I'll leave it here for anyone finding this thread later. As I come from SW like many, I tend to think about making a part, then bringing it into an assembly, then using parallel as a first constraint. But Fusion is intended to work differently in how assemblies are generated in the first place. This is a really good video I think should be mandatory viewing for anyone making anything with more than 2 parts. (Still doesn't cover the 'parallel issue' directly, but did help me work around the problem)

Thanks again.

Care to mention the workaround?

Well, I do not know why this marked as a solution, because it is not indeed. Workaround is not published as well. A solution point for providing this is undeserved, I think. Concidering author is not replying to questions too. @kjav
