This command is identical to the 3D
Viewer Window, except that this one loads a Carlson Grid GRD,
TIN or FLT file. After the surface file is selected, the 3D viewer
is shown.
On the Settings tab, there is an option to show
contours.
On View Control, the larger pointer button puts the viewer in
TIN edit mode. In this mode, the TIN Edit function list is
enabled.
Swap TIN Edge: Double-click on a TIN edge to swap the
connection points between two triangles.
Add Breakline: Double-click on a TIN point to set the first
breakline point and then double-click on the second TIN point to
create a breakline in the TIN.
Remove Point: Double-click on a TIN point to remove it from
the surface.
Remove Triangle: Double-click inside a triangle to remove it
from the surface.
Set Point Elevation: Double-click on a TIN point and the
program will prompt to enter the elevation.
Undo: The undo button next to the TIN Edit command list
allows for undoing the last TIN edit.
When the TIN is edited, the program will prompt for whether to
save the TIN when you exit the viewer.
The rest of the functions in this viewer are the same as documented in the 3D Viewer Window command.
