Sloped building pad cutting into topogaphy

[grantkjones]

Hi, is there a way to have a sloped building pad be level at the bottom and sloped at the top?  currently they are a set thickness(depth) and dive into the existing topo, so if it was IRL they would be excavating a bunch out then filling it back in immediately. Thanks.

in.

What about two BPs - one sloped and the other not?

Flat building pad below + Sloped floor above.

Or a thick building pad with a sloped void.

Image above help?

Ah, got it, void did the trick, thank you.

Don't you want to slope the earth under the pad?  

....more cost-effective, but whatever.

Yeah images did help thanks, for some reason when I replied originally they weren't showing up.  Void cut was the go for me.

I wanted to avoid the building pad diving down into the existing earth.  The site is being filled up above flood level (the green hatched section).  I'm using the building pad to show the fill. When I sloped the building pad from new fill level down to existing, it kept its thickness parallel instead of grading off to nothing at the bottom.  Essentially I wanted the building pad to create a triangle in section view but it wasn't.  Using the void cut to create the slope sorted it.

To calculate fill?  If so, there's another way you can get there in Revit.

Not specifically to calc fill, but that would be handy. It was more for when I cut a section I don't have to do too much to it in terms of linework, filled regions etc. How are you doing it in these pics?

With 2 Building Pads, as mentioned above. Topo fill is a by-product of creating the pads.  If pads are above the Toposurface, then Revit fills the in-between space with dirt, so to speak.  All quantifiable.
