🎥 Welcome to Episode 7 of the Fully Defined Build & Learn Series.
Today we model the smallest—and possibly trickiest—part in the whole set: the LEGO Technic hinge cylinder. This tiny part has complex details, subtle draft angles, and multiple ways to approach the build. You’ll see how I troubleshoot the shape, rebuild after a SolidWorks crash, and refine the final model.
🏫 What you’ll learn
🔹 Driving a right-hand helix and sweeping a custom thread profile
🔹 Fast end clean-up with offset planes, through-all cuts, chamfers & fillets
🔹 Converting a crash-prone build into a cleaner, more stable workflow
🔹 Identifying geometry mismatches and iterating for accuracy
📦 LEGO Set: Volvo Wheel Loader set 30433
📐 CAD Software: SolidWorks 2023
