Positioning pads

[mandrea.cis]

I think it could be really useful if building pads could be placed like toposurface (with elevation points) when working with complicated projects. Pads have to be drawn and placed like floors and there´s only the option to place a slope on it, but when working (for example) on parking lots  with a complex topographical surfaces sometimes it is needed to work with pads with multiple slopes. Thoughts on this?

I'm not clear why sloped pads don't work for you.

Place a floor above the pad and edit sub-elements to create slopes.

Are you maybe wanting your hardscape to follow the Toposurface? There's a technique to do this. Export your Toposurface  to DWG and then insert the DWG into an In-Place Massing Session - and then Finish and Close out of In-Place Mass and apply Roofs to Mass Face.  

FWIW: Railing also hosts to Toposurfaces.
