Select a Boundary (optional)
You can optionally define a boundary using a closed polyline for the
points that are staked, which will limit the computation of the TIN
surface within the selected boundary.
A valid polyline must be closed, and the line must not cross over
itself, such as in a figure eight.
7. To select a boundary, tap the
%RXQGDU\« button, which will
open the Choose Polyline screen.
