neuralCAD-Edit - Valid Output Rate: leaderboard
Metric: Validity (from 0-1, times 100): share of edits that produce a valid CAD model, on the 192 neuralCAD-Edit requests (expert CAD designers' video, speech, drawing and text edit requests on Autodesk Fusion models), the model editing the input STEP model by writing and re-running CadQuery scripts in the authors' harness with visual inspection; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 3 models tracked.
