Slider Crank Mechanism Design in FreeCAD | Parametric CAD from Scratch

Learn parametric CAD modeling by designing a complete slider crank mechanism in FreeCAD from scratch. Every internal combustion engine, reciprocating compressor, and hand-operated water pump relies on the same kinematic chain: a crank, a connecting rod, and a slider. In this build we create fully parametric dimensions that let you explore how link lengths affect stroke, velocity, and mechanical advantage. What you'll learn: • Navigate the FreeCAD interface and workbenches • Create fully constrained 2D sketches (geometric + dimensional constraints) • Build parametric 3D parts controlled by spreadsheet parameters • Assemble multi-part mechanisms with motion constraints • Generate professional technical drawings for documentation Real-world applications: internal combustion engines, reciprocating compressors and pumps, sewing machines, and hand-operated water pumps. 📖 Full written lesson (free): https://siliconwit.com/education/para... 🧪 Try the interactive simulator first: https://siliconwit.com/product-develo... 🎓 Full course: Parametric Mechanical CAD with FreeCAD: https://siliconwit.com/education/para... #FreeCAD #SliderCrank #ReciprocatingMotion #KinematicDesign #ParametricDesign #MechanismDesign #CAD #MechanicalEngineering #SiliconWit Join our community and stay up-to-date with the exciting worlds of engineering, computing, science, and philosophy. 🌐 Website: https://siliconwit.com/ 🔗 Linktree: https://linktr.ee/siliconwit 📂 GitHub: https://github.com/SiliconWit 💬 Discord:   / discord   📘 Facebook:   / siliconwit   👥 Facebook Group:   / 5984180241640422   📸 Instagram:   / siliconwit   🎵 TikTok:   / siliconwit   🐦 Twitter:   / siliconwit   👔 LinkedIn:   / siliconwit   🔴 Reddit:   / siliconwit   💡 Quora: https://www.quora.com/profile/SiliconWit 📌 Pinterest:   / siliconwit   📺 YouTube:    / @siliconwit
