@skysteam: Alright so this is how I faked a flexible airbag in SolidWorks based loosely off something like an RE6. I started with a sketch that basically defines how I want the bag to move, locked in my compressed and extended heights, then turned the line + arc into a single fit spline so everything can actually reference one clean path. From there it’s just stacking up parts — end plates, rings, middle section — all free to move, then mating their origins onto that spline and chaining symmetry mates between each piece so they all kind of average each other’s movement. That’s what gives you that “bag-like” motion. Problem is it’ll twist if you leave it like that, so I had to add top and bottom points and force them onto the spline as well to keep it tracking properly. It’s a bit smoke and mirrors to hide gaps and stop things pushing out weirdly when compressed, and yeah sometimes SolidWorks just locks it up for no reason, but for a quick motion check it actually does the trick. #solidworks #mechanicaldesign #engineering
