Convert DWG 3D Solid terrain to Revit Floor

[Burak_Baran]

Hello all, 
I have dwg file which has 3d solids define my terrain for greenary as below;

And in my working area in revit I have flatten floors but seperated to 280 floors for BIM purposes as below;

The issue is I need to implement that dwg terrain to my revit floors and doing each 280 floor manually is disaster,
I tried dynamo ,mass,bind link ,importing in family,3d Civil,etc.
First problem is converting this 3d solids to floors,
second problem is seperating accordingly that floors to my seperated floors area without loosing BIM values.

I am using Revit from 10 years and never stuck like this before ,
Thanks for your great minds and support.
Attaching small part of DWG 3d solid part for your reference .

use two dynamo scripts:

• one for converting cad mesh to topography surface (not toposolid): https://www.linkedin.com/pulse/toposurface-from-mesh-revit-maciej-wypych/
• one for adjusting floors to that topography created: https://revitdynamo.com/collections/dynamo-scripts/products/floor-follows-topography
