How to Model a Spiral Parking Ramp in SketchUp | Step-by-Step Tutorial

Learn how to model a spiral parking ramp in SketchUp step by step for a multi-story parking garage.

In this SketchUp tutorial, I’ll show you how to create a complete spiral garage ramp from scratch using Helix Along Curve and NT Extrude, then duplicate the ramp between floors, add protective barriers, apply asphalt materials, and place structural columns around the spiral.

This workflow is especially useful for architects, parking garage designers, civil designers, and SketchUp users who need to create curved vehicle ramps efficiently.
