show sketch projections/constrains for older sketch

[rprovideo]

Hi

so I have a pretty complex design of a case, with everything modelled after the PCB design. I actually cannot remember how the pcb was referenced to the multiple layer of sheet metal, 3d printed plastic and cut plexiglas designs...but I am pretty sure buttons and other elements from the PCB was projected to said layers and cutouts were created.

As it happens, I need to move the whole PCB a few millimeters...I was expecting Fusion to (after a great deal of thinking) modify all cutouts for me, as the referenced elements were moved. But that is not the case.

So to check, I opened this sketch of the sheetmetal case. It has a cutout for a mic, a few buttons and a screen. I cannot move said cutouts, and if I try to dimension them it says the sketch is over-constrained. So there must be a projection somewhere. But I cannot see it. Nor can I see why its not moved with the PCB, if its indeed projected from there (and where else would it be). There are some constrain icons, and there is one I cannot identify (lower right corner of the middle rectangle). That could be the projection constrain, is there a way I can see what was projected?

Green dot is Fixed. Click on it and then click Fixed Constraint to toggle off.

But I suspect you need to remove some Projected relationships too.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

It’s not a file I want to post publicly but I can send it to you. 

I do NOT want to remove projected relationship. I need to move the component where it was projected from (I think) and I want these projections to move with it. I thought it will, but no.

The only thing I can determine from image is this Fixed Constraint.

...in lower right corner of the image above.

Can you post image of the expanded browser?

Do you have Capture Design History enabled?

tried to send you the file in a private message, but its not enabled.

You are correct, moving the source should move the Projected article.

You can’t Dimension Projected articles, they are treated as fully defined in the destination sketch.

Why are the six arcs, white?

Sounds like no timeline, to me, too.

Might help....

I prefer to communicate in an open forum. That helps everyone.

Browser image?

Timeline image?

My guess (without seeing the design, it is just that...) is that the move of the PCB takes place in the timeline after the sketch that includes the projected geometry.  If so, your fix should be to roll the timeline back to before the sketch, move the PCB, then roll forward.  You should not try to solve this by manually moving the projected geometry in the sketch.  That would defeat the purpose of the projection - to have an association between the PCB and the cutouts.

so I tried this way, went back to the very beginning when I imported the PCB, and moved it 5 mil. Then I stepped the next step, and I can see the sketch not being created to the right place.

It seems I used something else to project to the sketch. As a note to the developers, it would be great to be able to 'redirect' or relink a projection. Also projection constraints are basically not shown (unlike others which have a small icon) and can only be broken by the break link command, which breaks all links, it seems. I had a previous item here I Removed, but it seems those links were not broken, and now I can only break them all.

Also it would be useful for a projection to say what object it was projected from.

Relinking is under the Manage Lost Projection Dialogue.

Linked projections are purple, 

correct, Project before removing is obvious,

Source article is behind the sketch plane.
