Change sheet metal rule in derived part

[Anonymous]

I have a sheet metal part, that is basically the same part as another one, just with a few additional holes in it. That's why I used the derive function to create a derived part, so that every change I make on the original part will also be applied to the derived parts, which has, as I said only a few additional holes and needs to otherwise exactly match the original part. I had the parts manufactured and so far everything works fine. Now I changed the manufacturer and he uses different tools. Now I have to change the Sheet Metal Rule, so I can provide an acurate unwinding fitting the requirements of the manufacturer.

Since the sheet metal rule is als derived from the original part I can't change it in the derived part. So I assumed, that if I change it to another ruleset in the original part, the derived part will be updated too. Unfortunately this is not the case. Even when I don't change it to another ruleset but change the applied ruleset, the changes are not applied to the derived part.

This is a very big flaw in my opinion because I am stuck with the wrong ruleset in my derived part now and have to derive another part now with the changed ruleset and redo all the changes that I need in this part. That's not the constructive workflow I am used to with Fusion 360, it really hurts my efficiency and it creates potential errors and confusion. So is there any possibility to either update the derived sheet metal rule when it is changed in the original part (which i would prefer), or to change the sheet metal rule in the derived part by unlinking it from the original part's sheet metal rule?

Okay so the problem kind of solved itself. I derived another part and now the ruleset changes from the original part are applied. Still wondering why it doesn't work with the other derived part but at least now it works and I will only have to redo the part this once and not for every change in the ruleset.

If anyone encounters this problem: The second time I derived it as a subcomponent into a new construction. The first time around I derived it simply as new construction. Maybe that's what caused the problem with the sheet metal rule updates.

I have the exact same problem but my part is a new construction but I can't get the sheet metal rule to change or update on the derived part at all. It has completely broken my model.
