Terrain Builder Errors are always fun to decipher, luckily I have collected intel on many of them through personal experience.
CPolygonalArea::UpdateGeometry() - Skipped shape: invalid triangulation (triangle 1.6 fails). (polygon_18)
You can fix this error in Global Mapper by just loading and saving the shape file, or in Terrain Builder by using menu shapes → find by name, then select the polygon in the error, use action drop-down of “show and select”, click OK, then the polygon in question is selected now just hit delete key to delete it.
Definition for bad polygon; can for example be one where lines between vertices cross at some point.
