For some time now, I have been making plans with views from another position. Only I can't attach one side between the edges of the main view and that of the view from another position.
I know it's possible because solidworks puts it in its guide, but at home it doesn't work. Maybe an option to check off or something else, now I'm drying.
I think that's what you're looking for; see PJ. This is by way of example; You will have to put your piece with the side you want to dimension in front view and then create your view as described.
@AC Cobra: That's not it. The "other position" views are only created in assembly mode and allow to represent on the same view 2 (or more) positions of a mechanism (such as cylinder in/out).
I don't have an answer to the basic question, except that sometimes I succeed, other times I don't. I think there is a problem with SW: it happened to me that I was able to put the dimensions on a plan and not on its little brother (same SW version, 2 sub-assemblies of the same machine).
I don't know if it's the right and only method but you should be able to put a sketch line between the desired elements in the different views, put the constraints that are fine and then dimension this line (in controlled dimension of course).
