Underground garage - ramped drive

I'm helping a client/friend with the design of their home.

They want an underground garage that is partially under the house and partially under a patio. - no problem, the town allows it and the HDPro 2024 software can do that. The terrain and terrain hole aren't a problem eithery.

They sent me the picture that inspired the idea.


The problem is, I can't find the right way to put in the ramp and retaining walls of the driveway. I tried putting a terrain flat around the house and the drive and terrain elevation lines going down the drive to a lower terrain flat, but it turned out a lumpy mess.





PS. Caution about looking for the source of this screenshot of drone footage. :o

Sorry for not giving any details to my example but it was late and past my bedtime!!

Step to my example 

1: Draw 1st Floor plan

2: Draw Basement at 120” below 1st floor

3: Build Terrain with subfloor 12” above terrain and elevation lines set at 0” at the front and back 

4: Add terrain region in front of basement garage set at -120”

5: Draw retaining walls in the shape of driveway 


6: Added terrain regions at 0” and shaped to match retaining walls and around the house

7: Drew terrain feature for driveway 

8: Adjusted Lower terrain region to gat driveway even with basement floor

9: Changed fill colors to show different regions
