Dammmmn ! I've been searching & watching solidworks surfacing videos around for a while to perfect myself on a more academic side of things compared to what I learned by myself, and this is the first time I actually come across yours ! I really like how you take down the first layers of things here to get clean surfaces later on ! Things I kind of understood from tryharding when modeling, but made obvious here. Great and simple explanations too ;)
Thanks for the excellent explanation. Even though new torsion continuity relation has come your explanation enable me to understand the problem of having G3 relation before.
