Do rough surfaces have you on edge? Got a kink in your spline? Zen out and come to really understand how SOLIDWORKS surfacing works. Using unique advanced techniques, we demonstrate surface modeling workflows that allow you to quickly and easily create the most challenging shapes.
This series of video tutorials covers spline and curve best practices, geometric continuity and how to apply it, how to properly plan and layout complicated surface models, how to properly leverage each of the surface features and modeling strategies to surface the most challenging of shapes.
