From Flat Sketch to Working Machine - Onshape Extrude & Assemblies

🌍 This lesson is part of 4Hope Kenya's mobile STEM curriculum - teaching 250+ orphanage students in Nairobi straight through their phones. Less than 10% of Kenyans own transportation. We're building bikes and teaching real engineering to change that. Follow the journey → @4HopeKenyaMentorshipProgram What's up, future engineers! ⚡🛠️ Welcome back to Unit 5! In Part 2 we take everything from your flat 2D sketches and bring it into the third dimension. You'll learn how to extrude sketches into solid parts, then snap multiple parts together into real, moving assemblies using mates. 🔬 Whether you're brand new to CAD, prepping to 3D print, or designing your own machines, this is the lesson where parts stop being drawings and start becoming things. 🎯 What We're Covering: ⏱️ 0:00 – Intro & Welcome 🚀 0:20 – Unit 5 Overview: Onshape Part 2 📐 0:38 – What "Extrude" Actually Does (Add, Remove, Offset) 🧊 0:51 – Extrude in Action: Sketch → 3D Solid ✂️ 4:18 – Cut Extrudes: Removing Material 🔗 7:12 – Assemblies Explained 📥 7:31 – Inserting Parts into an Assembly 🧲 8:51 – Mates & Mate Connectors 🎚️ 9:20 – Degrees of Freedom 🔒 9:45 – The Fastened Mate (0 Degrees of Freedom) ➕ 12:38 – Adding More Parts to the Build ↕️ 14:18 – The Slider Mate (1 Degree of Freedom) 🏠 15:28 – Homework 2: Build a House (Optional) 🌳 16:05 – Bonus Challenge: The Platform 👋 16:48 – Outro: Subscribe & Stay Connected 💡 This video is part of the 4Hope Kenya Mentorship Program - real engineering education through hands-on practice! 🔔 Subscribe for more CAD tutorials, engineering breakdowns, and real-world problem solving! 👍 Like and share with anyone learning Onshape, 3D modeling, or product design! #engineering #onshape #cad #3dmodeling #STEM #education #design
