Conversion method

Include glass in the outer skin — windows and glazing panels close the façade (solid exterior only)

Remove internal detail — fill everything that cannot be seen from outside, keeping the exact outer skin (solid exterior only)

Output maximum dimension (mm)

The longest side of the printed model. Required for solid export.

Solid exterior unions every building element into one closed solid, seals windows, doors and shafts, and fills enclosed rooms so only the outside skin remains. Loose fragments smaller than 1% of the building are removed.
