🎥 Welcome to Episode 6 of the Fully Defined Build & Learn series.
Today we reverse-engineer the large yellow 3 × 5 × 3 curved rear panel (part 24116) that gives the Volvo its swoopy bodywork. You’ll see how a few well-placed reference points and some sketching tricks tame its compound curves.

🏫 What you’ll learn
🔹 Using stud spacing (3 × 5 × 3) to lock down key pin positions fast
🔹 Radius-gauge “eyeballing” + tangent constraints for smooth outer curves
🔹 Mirroring an asymmetric half-body and adding single-side cut-outs
🔹 Quick sanity-checks in the assembly: interference & fit tweaks
