I have a set of vertical columns of linear rails that can move indepentently. These are all between two fixed columns. Because of the way covers, they cannot be closer that 10 inches apart nor further apart than 100 inches. Right now I start at the left fixed column and use limit travel constraints to get it mostly right, but when I try to use a limit travel constraint between the final moving column and the right fixed column it's overconstraining. Right now if I'm not careful I can drag the moving columns well outside the frame while still respecting the constraints. Is there a better way to go about this? Thanks in advance. I probably wont be able to respond to any questions or ideas until monday morning though.
