In one of the most exciting feature releases this year, Onshape introduces the Query variable, which brings parametric selections to every user's fingertips. "Parametric" means that selections update intelligently and robustly to changes, ensuring rock solid, reliable regenerations, even when the number of bodies, or faces or edges changes. Selections form the foundation of every parametric model, and with this enhancement, Onshape brings new levels of flexibility, power and usability. Join me behind the scenes for another of my single-take rehearsals for demos that I am prepping for, test-driving new concepts, or generally practicing. Usually recorded late after all my normal work is done, you might enjoy some of the tips and tricks I hope to offer.
