How can this happen? I've gone into the sketch of the downstream feature, deleted all external relations, and still it has some unstated relationship to the upstream feature that causes it to be deleted when I delete the upstream feature. There is NO parent-child relationship between the two. This is infuriating!
I've even edited the upstream feature. It's a boss-extrude, and I've put it deep inside another wall so that it doesn't affect the body of the part at all. Still, when I try to delete it, SW tells me that SIX other features will be deleted! This is insane!
Can you post the part?
Sure, here it is. I'm trying to delete Boss-Extrude 16 through 19, because they're leftovers from when I had more instances of the lugs for tapped holes. I edited the sketches for those bosses, putting just a circle in each sketch, to make them as simple as possible, trying to eliminate relationships with other features.
The downstream features that I want to keep are related somehow to these bosses through the fillets that also show errors. But there's no logical reason for these relationships that I can see. I've also tried to fix these fillets, but they're complicated face fillets and I haven't found the magic combination of selected faces that'll work.
I can't believe how much time I spend trying to coax, tease, or fool Solidworks into letting me move ahead!
When you delete something there is a pop up window prompting you or asking you if you want to delete it or not. It also can contain child things in this pop up box that will also be deleted. Before selecting yes to this pop up box, look closely at the check boxes at the bottom of this pop up window. De-select the "delete children features" or something to that effect. Anything downstream of the thing you delete that has a relation to the deleted thing will remain in the design and feature manager, however it'll have some sort of problem that you'll need to correct. This is a big time and frustration saver.
Holy cow, how long has that box been there? I never knew I could opt out of deleting child features along with the parent!
it was added in 2013 or 2014

Just to be certain, have you verified that there truly is no parent child relationship using the right click Parent/Child... menu option?
That's correct. What I discovered is that there seems to be a connection via a fillet in between them in the Feature Manager, but right-click Parent/Child doesn't show this relationship.
Let's call the features A, B (fillet) and C.
If I delete A, SW wants to delete B and C.
If I delete B, SW wants to delete C.
But Parent/Child shows NO parents for C (except the sketch plane, I suppose).
