Sloped floor and its volume

[atisklavins]

Hello all,

I ask for your assistance regarding floors and its volume. I have to design floors on ground and in some cases the slope is on bottom level, top stays flat. And I have to divide the floors into parts (days of casting)

I came to conclusion that there are 2 ways to make floor with bottom slope:

1. By making sub layer floor with slopes and cutting geometry. But when I apply a tag to floor parts, revit calculates the volume without the cutout (like for full thichness). 

Example: 

 - red is just additional floor (for cutting)

- thickness stays as defined in type properties. 

2. By making floors with diferent thichness and connecting by using edge. But this way I cant joint the geometry. Therefore cant create parts as I should. 

It just seems so reckless that the floors cant be sloped at bottom as above. 

Look forward to hearing from you!

What about In-Place Void Extrusion to cut away a portion of the Floor/Volume.
