🎥 Welcome to Episode 3 of the Fully Defined Build & Learn Series.
Today we tackle every Technic lift-arm / beam in Volvo set 30433: straight 5-hole, angled L-arms, plus the shorter yellow struts. You’ll see how a single master sketch can drive half-a-dozen part variants in minutes.
🏫 What you’ll learn
🔹 Using the Slot sketch tool & linear sketch patterns to lay out accurate hole spacing
🔹 Mid-plane extrudes & Geometry-Pattern mirroring to halve rebuild time
🔹 Fast recesses with Thin-Feature Cut and on-the-fly contour selection
🔹 Re-using a “parent” part to spin off colour- and length-specific variants in seconds
📦 LEGO Set: Volvo Wheel Loader set 30433
