The prompt
Create an accurate mechanical pulley in mm from the reference image. Generate a parametric CAD model with concentric circular geometry. Dimensions: OD Ø130 groove Ø80 inner diameter Ø64 central through-hole Ø20 overall axial thickness 40 mm stepped profile dimensions 5, 20, 15, 15 mm preserve the 60° and 45° features shown in the reference. Do not add spokes, holes, keyways, or invented geometry. Follow the reference exactly. Then create two orthographic drawing views: 1. TOP VIEW 2. HALF-SECTION FRONT VIEW For the half section, cut through the vertical center axis. Show the left half as a normal exterior view and the right half as a sectional view with 45° hatch lines. Do not hatch holes or empty spaces. Add centerlines. Align the top view directly above the half-section view. Engineering drawing style, black lines, white background, no perspective, no rendering, portrait orientation.
