GMS:TIN Commands

Menu Command	Description
New TIN...	Creates a new TIN and opens the TIN Properties dialog.
Lock All Vertices	Since it is possible to accidentally drag points, vertices can be "locked" to prevent them from being dragged or edited by toggling on this command.
TIN Settings...	Opens the Preferences dialog to the settings affecting TINs.
-	-
Triangulate	Creates triangles from existing vertices on the active TIN using the Delauney criteria. If triangles already exist, they will be deleted.
Subdivide TIN...	Opens the Subdivision Factor dialog letting the user enter a factor by which existing triangles will be split into smaller triangles.
-	-
TIN -> 2D Scatter Points	Creates a new 2D Scatter Point set from the vertices of the active TIN. The scatter points could then be used for interpolation.
TIN -> 2D Mesh	Creates a new 2D mesh from the active TIN, preserving the triangles.
Fill Between TINs -> 3D Mesh	Creates a 3D mesh, or adds onto an existing 3D mesh, by filling in the space between two TINs. A 2D mesh must exist and is used as a projection mesh for the 3D elements. Two TINs must be selected.
