Tests whether the LLM can emit cross-section views to capture features that
orthogonal silhouettes cannot see (blind holes, pockets, counter-bores). Decides whether Scanner is
a complete CAD architecture or only an exterior-shell tool. One round-trip.
Setup
Test object: mounting block 60×60×30mm with FOUR features:
• F1 M5 thru-hole at (-15, +15) — visible on TOP silhouette
• F2 M6 blind hole at (+15, +15), depth 12mm — invisible on silhouettes; needs cross-section
• F3 rectangular pocket 20×30×8mm at center — invisible on silhouettes; needs cross-section
• F4 counter-bore Ø9.5mm × 5.5mm deep at (-15, -15), Ø5.5 thru continuation — partially invisible
Three orthogonal silhouettes + two cross-sections (Z=20mm horizontal, X=0 vertical) requested.
