Gemini Canvas Shows Parameter-Driven 3D Design with STL Export

Google Gemini Canvas has demonstrated a workflow that moves from conversational design to 3D-printable output. In the showcase, an app built in Canvas lets users adjust mathematical parameters for an object such as a vase, view the updated 3D model, and export it as an STL file. The STL export comes from the app itself rather than being a native feature available for every Canvas project. Analysts note this is not a general-purpose CAD replacement, and it works best for repeatable object families with clear variables. The app's code must define the geometry and handle the export, so output quality depends on its design logic.
