Weldments (SOLIDWORKS)
Multi-body weldment modelling — structural members from cross-section profiles, trim/extend, gussets, end caps, cut list.
Definition
Weldments use the Weldment toolbar. Start with a 3D sketch (or 2D layout sketch) defining frame centrelines. Apply Structural Member with a profile from the SOLIDWORKS profile library (or a custom profile). Trim and extend members at intersections; add gussets, end caps, fillet beads. The cut list aggregates the individual structural members into a tabular schedule on the drawing.
Why it matters
Weldments are the standard tool for steel frames, machinery bases, conveyors, and structural welded assemblies — anywhere a multi-body part is more practical than an assembly of individual SLDPRTs.
Common pitfalls
- Mixing weldment bodies with non-weldment bodies in the same SLDPRT — cut list ignores them.
- Using a custom profile without setting Configuration Specific properties — cut list reports wrong metadata.
- Modelling the structure as an assembly when a weldment would be cleaner.
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).
