The prompt
Create a parametric 3D CAD model of a half-bridge ramp for a garden border. Total width (Y axis): 200mm. Total length (X axis): 220mm. Total height (Z axis): 115mm. The shape starts at X=0 with a height of 2mm, slopes up linearly to X=190mm reaching a flat top platform of height 100mm that continues until X=220mm. Along the inclined slope, add horizontal grip cleats (ribs) every 18mm, each 4mm wide and 3mm high, spanning the full width. Add safety side walls on both Y edges (Y=0 and Y=190mm), 10mm thick and rising 15mm above the ramp and platform surface. Hollow out the underside with a 6mm wall thickness to save filament, leaving a vertical flat back wall at X=220mm to rest flush against the garden border.
