AI technical drawing generator with Nano Banana pro
When conventional AI image generators cannot meet technical requirements, I created a solution that understands GOST and speaks the language of engineers.
This is a full-fledged image generation system on Google Gemini 3 Pro, the basis of thinking for Nano Banana Pro, which goes far beyond simple pictures. Multi-generation runs 4 variants in parallel via ThreadPoolExecutor, each with a unique variation seed for diverse results. Reference images (up to 14) are passed as a style guide — AI analyzes them and applies the visual style to the new generation.
But the main feature is full integration with the CAD world: automatic export to DXF via ezdxf (vector contours for AutoCAD), generation of A1 format PDF (841×594 mm) with the correct DPI for printing, and stamping according to DSTU (Ukrainian GOST 2.104). The stamp is generated by software: a frame with 20 mm indents on the left and 5 mm on the other sides, 185×55 mm cells with fields for Development, Verification, Approval, scale, mass, and organization. The text is automatically transferred to 2 lines or reduced if it does not fit.
Result: engineers receive not just pictures, but ready-made drawings with the correct stamps and in the required formats.
