Image models can reason about the building behind a perspective image and draw it in orthographic projection. Ask for all the drawings on one sheet so they share a scale.
A cardboard concept model and the orthographic drawing sheet generated from it

Make a copy of this workflow in your account to try it with your own images.

​
How it works

  1. Generate the concept (Flux 2 Klein) makes the concept image.
  2. Orthographic drawing sheet (Nano Banana Pro 4K) draws a 2x2 sheet: roof plan, front elevation, side elevation and section, as true orthographic projections at one consistent scale… no perspective.

​
Tips

  • Say which side each elevation is from, relative to the photo, so they line up with the image.
  • Treat the result as a sketch: check proportions before you trace over it.
