Use this FIRST for a compact model overview: dimensions, bounding box, body/face/edge counts, validity, watertight status. Use include[] for bodies, quality, pmi, inertia, or topology detail.

Find faces by type, area, radius, normal, quality, or body. Returns IDs, surface types, areas, radii, diameters, axes, normals. Use returned IDs in measure_distance, measure_thickness, measure_draft, or measure_geometry.

Find edges by curve type, length, radius, or dihedral angle. Returns IDs, curve types, lengths, radii, diameters. Use returned IDs in measure_distance or measure_geometry.

Measure distance between entity sets. Pass sources[] and targets[] for set-based measurement (e.g. clearance between holes and walls). Use summary="minimum" for the closest pair only.

Measure wall thickness across faces via ray grid sampling. Returns min/max/avg thickness per face. Use direction_mode="normal" (default) or direction_mode="axis".

Measure draft angles of faces relative to a pull direction. Returns draft_angle_deg, normal, and undercut flag per face. Positive = good for ejection; negative = undercut.

Ray tests, point analysis, cross-sections, and edge continuity. measurement_type selects the operation: ray, ray_grid, point_analysis, section, or continuity.

Compare two STEP files. Returns deltas: volume, surface area, dimensions, face/edge/body counts. Comparison minus baseline.
