Hi Ollie:
IIUC, you are now drawing a perimeter for a local CVX vector sloped / level flatten in SBuilderX using MSVE imagery ?
[EDITED]
Before you do that, we must enable the display of LOD-21 terrain grid Quad Area Points in SBuilderX, so we know here to place vertices relative to the positions of vertices within the underlying FTX EU England terrain mesh (for blending):
SBuilderX Menu > View > LOD Grid > Lod-21
FYI: The 5 Meter between-elevation-data-points terrain mesh for FTX EU England is a LOD-13 quad terrain grid resolution
Elevation data points for terrain mesh / flattens are placed on terrain grid "Area Points" for a particular LOD quad size.
LOD-13 Area Points are 8-LOD levels smaller ex: LOD-13+8=LOD-21 ...as discussed here (a good read some time later):

BTW: Of particular note might be the method that Jose (aka "simulondo") used for vertices in his project with SBuilderX:

[END_EDIT]
NOTE: After doing that, we will work on assignment of elevations to those perimeter vertices in a concurrent task session of SBuilderX and a live flight session in P3Dv4.5 via FSUIPC.
