Deleting TIN Lines
Deleting TIN lines may be required, for example, if the surface has TIN triangles
on the perimeter that are long and narrow. In this case, the triangles might
not be accurate for the surface, and should be deleted.
Surface TIN or Grid lines can also be deleted within a pond, for example, to
create a void area. By removing these lines, you can prevent contours from
being drawn through the void areas.
When an edge is removed, either an interior border that follows the adjacent
lines is created, or the exterior border is modified to follow the new lines.
Hide Boundaries
Hide boundaries mask areas of the surface so triangulation, and therefore
contours, are not visible in the area. Use hide boundaries to create holes in a
surface, for example, to mark a building footprint.
NOTE
When you use a hide boundary, the surface is not deleted. The full surface
remains intact. If there are surface TIN lines that you want to permanently remove
from the surface, use the Delete Line command.
