Sheet Metal (SOLIDWORKS)
SOLIDWORKS's sheet-metal feature set — base flange, edge flange, bend, unfold, flat pattern, cut list, K-factor.
Definition
Sheet metal modelling starts from a Base Flange (or Convert to Sheet Metal). Bends are added via Edge Flange, Miter Flange, Sketched Bend, Hem, Jog. The Flat Pattern feature unfolds the part using the configured bend allowance (K-factor or bend table). Drawings display either the folded view or the flat pattern, with cut list properties (length × width × thickness) on the drawing.
Why it matters
For fabricated parts, the SLDPRT must produce a clean, accurate flat pattern with correct bend allowances or the laser cutter and press brake will produce parts that don't fit. Sheet metal discipline is what separates 'CAD model' from 'shop drawing.'
Technical Deep Dive & Core Mechanics
From a geometric perspective, Sheet Metal (SOLIDWORKS) represents a parametric boundary representation (B-Rep) mechanism within SOLIDWORKS. The underlying geometric modeling kernel—whether Parasolid, ACIS, or a proprietary solver—maintains a strictly ordered history tree (Feature Manager). Each operation stores topological references (faces, edges, vertices) that are re-evaluated sequentially during model regeneration.
Common pitfalls
- Modelling as a solid then trying to convert — non-uniform thickness produces sheet-metal errors.
- Wrong K-factor for the material/machine — flat pattern is correct for the wrong physics.
- Using lofted bends without checking the resulting flat pattern — can produce non-developable surfaces.
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).
