When you start elevating a Floor, then it’s "sub-elements" are automatically activated. This will complicate the possibility to cut the Floor into smaller pieces, but also poses another problem if you want to add new breakpoints in the Floors boundary.
This is something that most of you probably already know 😊. New points in the boundary surface will end up at the Floor's "level zero", which in many cases will be at the sea level.
My method is based on creating all sub-surfaces as independent "complete flat" Floors at sea level. Then you adjust its boundaries in plan view in the traditional way.
The actual elevation it’s done in a larger main-floor (or main-topo) at the correct height. This main object covers the entire surface of the smaller sub-surfaces.
When the elevation is completed and the sub-surfaces have gotten their proper shape, it's time to project the sub-surfaces towards the “main-floor/main-topo".
The actual projection can be done in several steps, over and over again, depending on the elevation or if the boundary has changed.
Take a look at how it's done in this short video.
