We are trying to design a lift that uses multiple linear slides to obtain a certain height. We have constrained all of the linear slides in such a way that they should all be able to extend and collapse using the "Drag Components" command. What we actually get is the 1st linear slide (the lowest slide) moves, but the 2nd and 3rd slides will not move. We have attached the files in a ZIP folder. Please keep in mind that we downloaded the linear slide model off of McMaster-Carr (link inserted below) and was imported using a .STEP file format. We then reconfigured the .STEP file to animate, and it works in the sub-assembly of just the linear slide. The linear slide we downloaded was the 16" version. Please feel free to ask us any questions about our description of the problem. Does anyone have any suggestions?
