rp2040-test-board.glb traces: overlay top-copper gerber (real routing) onto the board top - registered to outline 6d ago

RP2040 Test Board

An Adom Fusion 360 electronics design (RP2040, SC0914) exported to a wiki-grade 3D model, with the copper routing made visible. Drag to orbit, scroll to zoom.

Why the traces are an overlay (and are real)

A Fusion STEP export does NOT contain the copper trace geometry (Fusion's own 3D PCB view does not show traces either), so a plain STEP -> GLB shows a bare green board. The traces you see here are the board's real top-copper gerber layer (GTL): rendered to an image, framed exactly to the board outline (Profile gerber, 23 x 10 mm), and overlaid on the board top with the same texture-registration used for silkscreen. So this is the actual routing, the QFN fan-out, the ground pour and the pads, in copper, sitting where they really are on the board.

Pipeline

  1. Fusion electronics design -> export STEP + gerbers.
  2. STEP -> optimized GLB via service-step2glb molecule mode (OCCT tessellation, gold pins, join/weld/prune, Draco).
  3. Render the top-copper gerber to a copper-colored PNG framed to the outline, overlay it on the board top.
