Hi All

I have placed two surfaces, one surface is the ground surafce, the second surface is 9.5m above the ground surface.

The higher surface is used as a maximum building height above ground and I modify this surface in the elevations to represent a red dashed line.

My problem is that when I add a subregion it attaches to the higher surface and not the ground surface.

Does anyone know how to move the subregion surface down to the ground surface?

Your process is really strange.  What is this higher surface - topography?  Why that?  Change this element.

Hi

No part of the building can not exceed 9.5 above the existing ground surface. The ground surafce in this instance has a slope.

I copied the existing surface 9.5m above and modify it in the 3d view to be semi-transparent, this allows me to see which parts of the building exceed 9.5m above existing ground. I also modify the surface in the elevations views to represent a red dashed line.

I have been told of a solution (yet to be tested), is to temporarily move the higher surface to the side or away from the ground surface, add my subregions etc and  then move the higher surface back into place.
