Help modifying a rigid group and resolving timeline warning

[Anonymous]

Hi all,

  I've been importing some parts from McMaster Carr for my slider drawers I'm building.  I'm nearly done but I have 2 issues.

When my parts arrived, they were slightly different in tolerances from the default specs.  As a result, I've needed to modify my drawer in the slider.  Specifically components in Drawer/Joints/Base and Aluminum Sliders and Drawer/Joints/Drawer Group.  To do this I've suppressed those rigid groups, then used push/pull and move to resize some of the drawer components.   Now that I'm done editing, I'd like to retain those groups, but have the components placed in their new position.  I thought if I edited, then saved, I could accomplish this, but it moves the components back to their original position.  If I try to delete them, I receive a warning they're referenced elsewhere, so I'm not sure how to resolve this. 

Second, In my root component, if I select the timeline, I see this warning at the beginning. 

Warning: Extrude1

1 Reference Failures

The profile reference is lost, try editing this the feature to reselect the lost profile.

I'm not sure how to fix this, any help would be greatly appreciated.  

Here is the url to my diagram.

Thanks in advance!

Hi @Anonymous,

The thing to remember with Fusion is:  everything is a timeline operation.  Even a rigid group.  So, the rigid group captures the positions of the components at that point in time.   Moving them later, even if the rigid group is suppressed, as you found, won't work, because when you unsuppress it, it will still put those components back at the positions they were in at that time.  The component position feature occurs later in the timeline.

Your choices to fix this are either to delete and re-create the group after the position feature, or to roll back before the rigid group and make the modifications.  Here is a quick video showing how to do this:

Regarding that first failed extrude:  There seems to be no features before that in the timeline:

My guess is that there used to be another feature or a sketch before that extrude, which is where the profile comes from.  Did you possibly delete something?

Hi Jeff,

 Thanks for the tip on the Rigid Group, I'll modify the position on the timeline.

In regards to the extrude, it doesn't really seem to connect to any feature I'm using, however when I go to delete it, I get an error that other features reference it.  I noticed several of my extruded 2d drawings that I've turned into components reference the outline of the original 2d sketch, even though you can't see it in the drawing.  Is this normal, or should I be approaching creating my components differently to avoid these "hanging" sketches that still seem to be referenced?

My goal is to  to clean up my component to only have the components I want in their final position with the joints defined.  Is there an easier way to accomplish this?

Thanks,

Todd

Hi @Anonymous,

I'm not sure what happened to that extrude, to be honest.  It has definitely lost its sketch.  I was able to build a new sketch for it, using project of the body produced by the sketch, then Break Link to make the sketch not depend on that extrude, then reordering the sketch to be before the extrude, then editing the extrude.  It's a bit of a kludge, but it will fix the error...

I came across this discussion because of the same error message "The profile reference is lost, try editing this the feature to reselect the lost profile"
In my case I had broken the link from sketch to extrusion, because when I edited the sketch, it became invalid to extrude from.  It was a tiny error in a rectangle, not having the vertices connected.  Hard to see until zooming in close.  Editing it and the extrusion all linked up to the sketch again, and followed the new shape
