shapebridge (gazi-faysal-jubayer)MCADConfidence: Medium

In a desktop STEP viewer, models over about 1 m were cut off or invisible because the camera far plane stayed at the 1 m default. A 300-part assembly showed 3 of its 60 plates, and a 2,500-part one showed nothing. Loading that assembly took 45 s, 42.5 of them in single-threaded WebAssembly OpenCascade.
