I am trying to simululate a hydraulic cylinder between two components (A & B) with an adaptive line.
I start a new part for the cylinder, make a line (not constrained to the origin, not horizontal, not vertical). I place a circle at each end of the line for ease of constraining later. I do not dimension the length of the line. I make the sketch adaptive. I make the part adaptive. I constrain one end of the line to part A. I attempt to constrain the other end of the line to part B, but cannot because the line will not change length. If the line is adaptive, why won't it change length?
Thanks for the help

I made two parts one with two sketches and two
workpoints in the air.  The other is a line with two workpoints on either
adapted fine when I mated the work points to each other.  What happens if
you select the opposite end first?  You may have to try different
combinations of points.  Part A and Point A, Part B and Point B, Part A and
first.  Good luck

Also look for grounding at the sketch
But very handy.

Thanks for the suggestions. Boy, it sure is picky. I wish it worked more reliably, as it sure is nice when it works.
