bim-forge (Frederik91)MCADConfidence: Medium

An LLM BIM authoring tool correctly read a wall's properties and units, then failed to place a cube 500 mm clear of that wall. The AI gets identity, transform, properties and units, but no product mesh or world bounds, and there is no linked-geometry query. 'This is not yet a geometry-awareness demonstration.'
