SOLIDWORKS Electrical 2021 introduces major enhancements across schematics and 3D. Designers can now route wires through clips more efficiently using new arrangement controls, with improved harness routing that supports splines for smoother paths. Separate 3D route assemblies provide greater flexibility for multi‑cable configurations, while a new terminal type manager adds customisable symbols for clearer documentation. BOM control is improved with an Exclude from BOM option, alongside new Excel automation tools for rapid project creation. Additional updates include enhanced wire management, an external archiver for scheduled backups, and a free Electrical Viewer for licence‑free project access
