Definition
Surfacing tools (Extrude Surface, Revolve Surface, Sweep, Loft, Boundary Surface, Knit, Trim, Untrim, Filled Surface, Ruled Surface, Offset Surface) build geometry as zero-thickness sheets that can be thickened into solids or used as input to other features. Curvature continuity (C0, C1, C2) at boundaries matters for visual quality.
Why it matters
Solid features alone cannot produce smooth consumer-product forms. For plastic parts, automotive trim, helmet visors, and any class-A surface, surfacing is the primary modelling approach.
Common pitfalls
- Knitting surfaces with gaps below tolerance — produces sheet bodies instead of solids.
- Lofting profiles with mismatched curvature — visible patch boundaries in render.
- Using surface modelling when solid features would be simpler and more parametric.
SOLIDWORKS Ecosystem Context
This concept is a core structural element of the SOLIDWORKS drafting and engineering environment developed by Dassault Systèmes. Dassault Systèmes' mainstream parametric MCAD — feature-based modelling, assembly mates, and 2D drawings tightly coupled to the 3D model.
Relevant SOLIDWORKS FAQs
❓ Is SOLIDWORKS available on macOS?
Not natively. SOLIDWORKS is Windows-only. Mac users run it via Parallels, VMware Fusion, or Boot Camp (Intel Macs). On Apple Silicon, virtualisation is limited. The official cross-platform alternative from Dassault is the browser-based xDesign on 3DEXPERIENCE.
❓ What's the difference between SOLIDWORKS Standard, Professional, and Premium?
Standard is the core modelling + drawings package. Professional adds CAD Library, PhotoView 360 rendering, eDrawings Professional, Toolbox, advanced sheet metal. Premium adds Simulation, Routing (electrical/piping), ScanTo3D, Motion. Most production shops use Premium; education usually uses Premium-equivalent.
❓ What is 3DEXPERIENCE SOLIDWORKS vs. traditional SOLIDWORKS?
Traditional SOLIDWORKS is a desktop product, files saved to disk/network/PDM. 3DEXPERIENCE SOLIDWORKS is the same desktop product but cloud-connected: files saved to the 3DEXPERIENCE platform, license tied to a Platform identity, and access to companion cloud apps (3D Sculptor / xDesign, simulation, PLM).
