Rendering from a sketch is a different job from restyling a photo. The AI has to invent every surface while obeying lines that were drawn quickly and imprecisely, so the prompt has to be firmer about materials and lighting than it would be for a photo.
These prompts include the two instructions that matter most for line input: remove the drawing language, and treat the lines as structure rather than as content.
Copy-ready AI prompt
photorealistic interior photograph, white oak flooring, plaster walls in warm white, matte oak joinery, linen upholstery, soft daylight from the window on the left, realistic materials and shadows, no line art
The base prompt for most hand-drawn interiors.
Copy-ready AI prompt
photorealistic architectural photograph of a contemporary house, white render walls, timber cladding accents, black window frames, mown lawn and mature trees, soft overcast daylight, realistic materials, no sketch lines
Overcast light hides sketch imprecision best.
Copy-ready AI prompt
photorealistic photograph of a modern building, board-formed concrete and glass, bronze frames, planted forecourt, bright overcast sky, sharp focus, professional architectural photography, no drawing lines
For grey-box and massing captures.
Copy-ready AI prompt
photorealistic retail interior, polished concrete floor, white walls, oak display units, black track lighting, warm accent lights on the products, no people, no line art
Track lighting is what makes retail read as retail.
Copy-ready AI prompt
photorealistic restaurant interior photograph, terracotta floor tiles, oak banquette seating in green leather, brass pendant lights, plaster walls, warm evening lighting, cosy atmosphere, no sketch lines
Evening lighting for hospitality, always.
Copy-ready AI prompt
photorealistic photograph of a courtyard garden, stone paving, mixed planting with grasses and olive trees, timber bench, water feature, soft late afternoon light, realistic textures, no drawing lines
Name two or three plant types, not a full planting schedule.
Copy-ready AI prompt
photorealistic architectural render based on this section, exposed concrete slabs, timber floors, glass balustrades, planted terraces, daylight entering from the top, realistic materials, cut edges reading as real construction
Works with hand or CAD sections.
Copy-ready AI prompt
photorealistic product photograph of the drawn furniture piece, solid walnut with visible grain, brushed brass hardware, soft studio lighting, neutral background, sharp focus, no line art
Good for bespoke joinery approvals.

Include the phrase "photorealistic photograph" and end with "no line art, no sketch lines". Architectural AI uses your lines as structural guidance, and that instruction tells it to replace the drawing language with real surfaces rather than stylise it.
Rough works. Clear, confident lines give the strongest result, but loose sketches render fine as long as the main geometry is legible. If the drawing is very light, photograph it in good light or increase the contrast first.
Yes. Line exports from AutoCAD, Rhino, Revit and ArchiCAD, and plain SketchUp viewport screenshots, all work with the same prompts.
Usually the prompt is describing the building rather than its surfaces. Let the lines define the form and use the prompt only for materials, light and atmosphere.
