Missing instance in assembly file

[Dale_Rosema]

I have a assembly model that is failing when I open it. I says that a model is missing. An instance of a family table was obsoleted, but I do not see where in the assembly that the missing part is suppose to be. When I go back into the family table, and temporarily add the instance it is looking for, the assembly model is "happy" but I still do not see where the model it was looking for is supposed to be. Here is the tree and model info screen shots both before and after adding the missing instance back into the family table. Again, I do not see where the part is suppose to be. Is there a way that it could have been hidden?

Try looking at the reference viewer. Sometimes it shows broken links or missing information that you can't find elsewhere. 

[Dale_Rosema]

Before or after "recreating" the missing instance.

[StephenW]

Good question.

I would have to say try whichever you have open first and see if it shows anything. Then try the other.

I would expect it show better without.

[Dale_Rosema]

This is before I recreated the missing instance.

[StephenW]

RMB on the dotted line there and select INFO and see if you get any clues

[Dale_Rosema]

It looks like it is being used as a reference, but I am not sure how?

[StephenW]

Maybe try with the instance re-created. Maybe it will give you a clue...maybe??!?!

[Dale_Rosema]

Does it look like there is some sort of circular reference? 

Comp id 877 (1013_3071.prt) -> 1189_2000.asm -> 1013_3071.prt

[StephenW]

Trail by error.

Look at another component (one you know its there and is all good) and see if it says the same thing.

[Dale_Rosema]

Here is an instance that is from the same family table - used twice before the "missing" instance.

Spoiler

Even if I could just delete it after I recreate it, I would be happy, but I cannot find it other that using the reference viewer or model information.

[StephenW]

Welll, we've passed the level of my ignorance!

If there are any other failures or anything in the model, that would be where I would look.

I really haven't gotten anything useful to say know sooooo...if it was my problem, I would cuss a little, then maybe recreate the assy if it was easy enough.

Looks like it is Feat ID 877 in the assembly.

May be the result of replacing a part with "Remember These Components" checked.  What does the reference look like when instance is restored?  I there a trash can to remove it.

[Dale_Rosema]

It has changed the dotted line to a solid line. Where might I find that trash can?

The (2) instances of the 1013_3080 are from the same parent model and typically it would have been replaced by  "Family Table". If I come across other errors, I usually just recreate the missing instance and swap it out for the instance that it is suppose to be, but since this isn't in the family tree, I am at a loss.

[kdirth]

Looks like this:

[Dale_Rosema]

There is no trash can to click on.

In the assembly model info,  Look in the feature list for ID 877.  This will show you feature No. to help you find its location in the tree.

[Dale_Rosema]

 It is in the feature list, but not in the tree:

[Dale_Rosema]

I deleted 1189_2000.inf and recreated it. This is also with the instance temporarily back in the 1013_3000 family.

[Dale_Rosema]

Full path with the "instance not added to the table"

[Dale_Rosema]

Tried something unique: I highlighted datum plane "Right" to delete from the tree. This what showed up:

I did not follow through on this, but is there is a way to get the 1013_3071 highlighted for deletion without trying this.

[pausob]

Hi, wondering if you "followed through" on that trick which looks like a neat work-around.

I assume that hidden "suspend all" option is there, so shouldn't be too much clicking...

[Dale_Rosema · Accepted solution]

I renamed the file before trying this.

I decided to delete the front plane (lower in the tree and can be recreated from the right and top plane).

I suspended all of the items except the missing item.

After recreating the front plane, I was able to reattached any constraints that were looking for the front plane.

Every thing is now happy with the structure.

[pausob]

That's cool.  Instead of deleting the top feature, could you simply suppress it? - because that should also trigger that "children handling" dialog box...

[Dale_Rosema]

That's good to know for "next" time.  🙂

[kdirth]

Do you have everything checked to show in the tree filter.  It should be between 1013_380 and 1116_6011 judging by the No. in the feature list.  Turn on the Feat # column in the tree to see where it should be.

[kdirth]

Is it in one of the groups?

[Dale_Rosema]

It is not in one of the groups nor in any of the subassemblies. I expanded everything all the way just to check.
