Headless-Chrome capture, orbit frame 270: the massing by level with the layer panel, space inspector and cited dimensions.
GROK · GLB IN BLENDER 5.2 · 2026-09-22
The same massing as GLB rendered in Blender (EEVEE, October sun), turntable frame 120; the file holds Z-up data, so it is rotated on import.
