I have a sloping site on which I have created a topo surface and then created a graded region to suit the proposed surface levels.
I have a basement car park partially below the footprint of the building structure above. The building structure sits on top of a podium slab the top of which is below what is to be the finished ground level of my graded region.
Whenever I use a pad to remove the ground within the confines of the basement it cuts away the topo surface above the basement but outside of the building footprint. i.e. it cuts away my finished ground surface as well.
This looks wrong in my 3d views where I want to show a landscaped grassed area over the roof areas of the basement.
Is there any way I can I can set Revit to cut away the building pad volume between the basement floor slab and say the top of the podium slab roof only, thus leaving the topo surface visible above this level in all other views.
Am I doing something wrong. Any help much appreciated.
