Adding Building levels to existing ground

I have an existing ground surface with all different z co-ords and im trying to add three proposed buildings to my exisiting ground with all the builidngs having a level of 32.5 as a minimum, however at some points the ground is higher than 32.5 and I only want to raise my existing ground to 32.5 within the proposed buidling layout if it is below 32.5 as im doing a flood calculation. What do i need to for this? Thanks.

Hi,

 

I would do the following steps:

  • create a user-spezified contour at 32.5
  • extract that contours to get polylines (command _AeccSurfaceExtractObjects)
  • copy your EG-surface
  • use the extracted contours to make islands in the copied surface
  • now you can raise up the copied surface

Changing existing ground is a sure way to make any grading problem go away Smiley Wink

 

Surley I jest, but typicaly we don'r change existing ground we build on it and cut into it - two different models. Then they can be combined.

Thank you
