Nora3D is AI CAD for functional parts. Describe what the part needs to do or its dimensions, then keep refining the model with plain-language prompts or regular CAD tools. Import STEP files, inspect each change, and export STEP or STL. Runs in the browser on desktop, tablet and phone. CAD tools and STEP and STL export are free, with a limited one-time AI credit gift. Paid plans start at $9.90 per month. Imported STEP files do not restore the original feature tree.
Functional parts often need more than a one-shot generate. Nora3D lets you describe what a part needs to do or its dimensions, then keep refining the same model with prompts or regular CAD tools, and export STEP or STL.
