Edit joint problem

[Anonymous]

Hi All!

faced with such a problem - edit joint not possible for components vs holes. One component of two was lost reference to hole...

To test, I created a simple project (see below).

Option 1:

Create Component:1>create cylinder> create Component:2>create cylinder>create sketch at the cylinder surface> place point>create hole at the point>create joint (rigid or revolve does not matter) between Component:1(center of the cylinder) and holes of te Component:2.

After creating joint is possible to edit it with no problem.

Also joint can edit if I create hole without sketch.

Option 2:

Create Component:1>create cylinder> create Component:2>create cylinder>create sketch at the cylinder surface> place two (or more) points>create two (or more) holes at the points>create joint (rigid or revolve does not matter) between Component:1(center of the cylinder) and one of the holes of the Component:2.

After i try to edit the joint - it is impossible. Link with the hole is lost - button "Select" indicate red arrow.

Сan somebody check it or recommend another way to joint components through the holes?
I think it started after last update of the Fusion 360.

Thanks,

Alex

Thank you, @Anonymous for your pictures and clear description.  This is most definitely a Fusion bug.  I will report it and we will fix it as soon as possible.

As a workaround, if you create the holes in separate features, you can edit the joint.

We apologize for the inconvenience, and hope to fix the bug soon.

Thank you, Jeff Strater

for the explanation and advice.

Hi @Anonymous, thanks a lot for reporting the issue to us. The bug had been fixed and will be available on the coming release update.

Currently, the workaround is to create the hole one by one (one sketch point one hole feature).

Hi Bruce!

Thanks for the advice.

I want to add the information (about bug holes like references in a sketch) - perhaps it is because of the same reason.

Step 1:Create box > create sketch > create two points > create two holes.

Step 2: Create another sketch > create line between  the two points > create point at the midpoint of the line

Step 3: Create hole #3 at the midpoint

Step 4: Edit sketch with two holes and move hole #1 to another place (change the dimensions).

Step 5: Exit from sketch  - hole #3 do not move to the midpoint of the holes #1 and #2.

I have always used this method in the Inventor and it worked. Now I am look around the design to detect lost sketch references...

Hi @Anonymous,

Yes, you got it. This is caused by the same reason. If you create the hole separately, your workflow should work as expected.

Thanks again for reporting issue to us:)

I'm having a very similar problem. I have a design where none of the joints I create are editable. However, rather than getting the red arrow as in this example, the joint is completely lost. Neither of the two reference points are there when editing. The "alignment"part of the edit joint dialog is also missing. It will still allow me to click OK without selecting anything, but the components joined by the joint are not in the correct position until I do a "compute all", at which point they snap back into position. 

Even if I re-select the two joint origins, when I click OK the components do not move, and when I do a "compute all", they snap back to the original position of the joint. The selection I just made has no effect.

I made a short screencast to show the effect:

@jeff_strater check out FUS-24805. I think what I've reported there is similar to this?

[jeff_strater]

Thanks for pointing this out.  This could be the same problem, @soswow.  The one difference is the design in @patrik-web's post uses internal sub-assemblies, while what is in FUS-24805 seems to be a problem with external (linked) components.  I'll ask the team to take a look at these in closer detail.  @patrik-web, would it be possible to share your design with us, so we can investigate?

Thanks,

Jeff

I imported all the linked components in my design and the problem remains. Take a look at http://a360.co/1TwCx8i and try to edit "Rigid6" in the "Fuel pump box:1" component.

@patrik-web, thanks for sharing the model. I was able to reproduce the probem and has already forwarded the case to the developmet team. 

It seems there is something wrong in the sub-component "SAE J1926-1 AN-6 O-ring port plug". Could you let us know how the model was created? Did you insert external references then break links? If yes, could you share that component as well for us to reproduce the problem from scratch? 

Regards,

[patrik-web]

Thanks for looking into it.

Yeah the AN-6 plug was an external component that I broke the link to. It's pretty simple, you can get it at http://a360.co/1XvIsd5.

[NicolasXu]

Thanks, Patrik.

We will keep trying to reproduce it from scratch. Meanwhile, for your original assembly, you may delete the Rigid6 and recreate one, so you can continue your work.

Thanks again and sorry for the inconvenience.

Any updates on this one. I have the same problem. With external linked parts that were created in 360 with simple cylindrical mates where after I hit ok, one reference is lost but no errors appear most of the time just an incorrect joint. The animation is correct prior to the ok but after the part could be reversed or perpendicular to the selected. Once and a while I get an error on the ok but rare.

I will add screencast if my IT department allows the installation.

Thanks,

Hi Todd,

Thanks for reaching out to us. It sounds a different issue. Would it be possible to share the design with us for further investigation? You can share the design link by enabling the download permission. The share command is available under the File menu.

I am trying to get the pins to slide in and out of the holes following a
cam engaged with the slots. This is preliminary and has serious
interferences with the cam but my issue is with the pins.

I cannot use screen cast as IT won't let it install.

Hi Todd,

Thanks for sharing the design. Something is wrong in this case. I can reproduce your problem and have reported to the development team for investigation (FUS-25824). Hope it can be fixed soon.

Thank-you,

FYI it also occurs in the OSX version, the Windows version update didn't help with this problem.

Cheers,

Todd

Hi,

I'm not sure this problem is solved (as in the issue topic). I'm still facing edit joint problem.

When I try to edit joint, the joint completely lost.

I found the problem arises now, when I select the surface before launching
the command.
