convert this floor plan into a realistic isometric 3d view of a full house show the space from an elevated angle with furniture walls and details visible create an isometric 3d model from the provided floor plan using a strict trace approach primary instruction non negotiable treat the floor plan as a locked reference you must perform a direct literal trace of the geometry only do not interpret optimise clean align or redesign anything do not infer missing information do not correct perceived mistakes do not simplify irregular shapes or wall offsets structural accuracy rule the output must be a 1 1 geometric translation of the plan every wall position thickness angle offset and junction must remain exactly as drawn if something appears unusual or asymmetrical replicate it exactly scope stage 1 only walls generate only external walls internal walls door openings voids only no doors window openings voids only no frames or glazing strict exclusions no furniture no built ins no cabinetry no fixtures no floors or floor finishes no ceilings no styling or decoration no added architectural elements of any kind geometry handling preserve all irregularities and non standard angles do not straighten align or square off any walls do not merge or adjust wall intersections maintain exact proportions and spatial relationships visual style isometric view uniform wall height neutral material matte white or light grey only no textures minimal ambient lighting only soft subtle shadows for depth important if any part of the plan is unclear do not guess leave it as is rather than modifying the structure this is stage 1 structure only built ins objects and styling will be added in a separate step use the same furniture as shows on the plan do not change the orientation of the floorplan
