How would I make this selection flat and later modify its elevation? The elevation map is represented in 3 dimensions and is a high-poly, computationally generated product of dronedeploy. Map that needs modifying

  • $\begingroup$ For the 2nd part of your question, please add to your question an example of your elevation map data. It might be directly usable (if it's a grayscale displacement map where color value corresponds with height), or might need some scripted conversion. $\endgroup$ – TLousky Mar 1 '16 at 11:01

To flatten a part of your mesh:

  1. Go to edit mode.
  2. Select the bits you want to flatten.
  3. Change the pivot point to "Active Element" through the pivot point menu. enter image description here
  4. Deselect and reselect an element (vertex/edge/face) that represents the height for your flattened selected. This will set this element as the active element. The entire mesh will be flattened to this height.
  5. Scale to 0 on the Z axis via: S-->Z-->0. enter image description here

That's it! enter image description here
