measure_model to verify dimensionsanalyze_printability to check FDM suitabilitycombine_models to integrate with other parts if neededthread_type="iso"): Standard metric bolts/nuts. Specify major_diameter and pitch.thread_type="acme"): Power screws, vises, lead screws. Specify size (e.g. "3/8").thread_type="metric_trapezoidal"): Metric lead screws. Specify size (e.g. "10x2").thread_type="plastic_bottle"): ASTM D2911 bottle caps. Specify size (e.g. "L38SP400"). Use manufacturing_compensation=0.2 for FDM.Common sizes: M2, M2.5, M3, M4, M5, M6, M8, M10. Format: "M3-0.5" (diameter-pitch).

Searches the step.parts catalog for off-the-shelf CAD parts (actuators, servos, motors, connectors, fasteners) and downloads canonical STEP files. Resolves fuzzy part names and aliases.
Provides 7 Python CLI calculators for AEC computational design: geometry analysis, structural checks, solar radiation, panel optimization, mesh analysis, material estimation, fabrication costs.
