Hands-on: Use Draping Surfaces to Warp a Parking Lot for Drainage
Engineering Task: Grade a Parking Lot with a Cross Slope and then a warp to ensure positive drainage.

Imagine a fairly straightforward grading requirement, but a complex curbed parking lot with lots of islands and detail work.
Computing appropriate slopes along each element would be ridiculously difficult. An easy and intuitive technique is to create a "draping surface". The draping surface provides a simple intutive - and easily changed - terrain that design elements get their elevations from.
