I think work features should have an option to "auto resize to inputs".
my situation is that I'm using 3d sketched to sweep hose parts or to constrain pipe runs.
For the hoses I use offset work planes in the 3d sketch to prevent the co-linear lines from reversing direction on adaptive model changes. The problem is they don't follow the inputs if there is a large change so I have to manually drag them or they will be off in space somewhere. The screen shot below shows a not so bad case but they can end up meters off and they are small so hard to see. The alternative is to use auto resize and then they resize to the whole part which is too large and again not useful.
For pipe runs I place work axes on the 3d sketch because I cannot constrain to the 3d sketch lines (that would be another good feature). Again, they are created / auto resize to the full part size and I have to manually drag the ends to match the 3d sketch lines otherwise it ends up a mess. I've shown a screenshot below with manually resized axes.
In both of these cases an option to "auto resize to inputs" would be very helpful.
