How to Design Curved Ramps with Perfect Drainage in Rhino 8

​Struggling with complex parking ramps in Rhino 3D often leads to "pitted" or broken geometry, but it doesn't have to. In this tutorial, Bimo Adi Prakoso from Sentra Grafika Kompumedia demonstrates how to model a fully functional, curved multi-story ramp in under a minute. Beyond simple modeling, you’ll learn to incorporate critical engineering details like inner-edge drainage slopes and seamless level transitions using advanced blend curves. By utilizing native Rhino 8 tools and custom macros, this session proves you can achieve professional, automated results without relying on expensive third-party plugins.
