1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Surface Modeling: Case StudyA thin-walled part from start to finish: extrude, revolve, trim, knit, thicken.↗ Surface Modeling: Complex BlendsTrim, loft and fill to blend intersecting surfaces.↗
2. Key takeaways
The typical method: create surfaces larger than needed, then trim them against each other.
Trim Surface cuts with a sketch or another surface; Extend Surface lengthens an edge that is too short.
Knit Surface joins the faces into a single body and can create a solid directly if the set is closed.
Thicken turns the final surface into a thin-walled part, on one side or both.
Tip
Name your surface bodies in the Surface Bodies folder: on a model with 30 surfaces, that is what lets you find your way around six months later.
