There is a certain number of tricks we can do with right-click on a model. One of them is to modify additions.
I have noticed that when I change a skirt offset (and make only 2 lines but I’m not sure if this does matter), the right click can’t find skirt anymore. Anyway, it can find it in a place where it was before offset change that is 2 mm from the model.
BTW, I still in strongly disagree with your decision that none of this useful customizations having set of explicit parameters and defaults. Every time I do a printout, I need to go to the skirt and every time I set exactly the same values. Sorry, that’s ridiculous.
