Feature Objects

When the TIN module is active, the following commands can be found in the TIN menu:

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.
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 that allows entering a factor by which existing triangles will be split into smaller 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.
Horizons → Solids...
Opens the Horizons to Solids wizard which can be used to create solids from a combination of boreholes, TINs, and conceptual models.
Horizons → 3D Mesh...
Opens the Horizons to Mesh wizard which can be used to create a 3D mesh from a combination of boreholes, TINs, and conceptual models.
Horizons → UGrid...
Opens the Horizons to UGrid wizard which can be used to create a UGrid from a combination of boreholes, TINs, and conceptual models.
Convert To...
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.
TIN → Extruded Solid
The Extrude/Offset Tin → Solid dialog
Opens the Extrude/Offset Tin → Solid dialog which is used to extrude the TIN vertically up or down to form a solid.
TIN Boundary → Polygons
Creates a new coverage containing a polygon derived from the outer boundary of the TIN.
TIN Thiessen → Polygons
Creates a new coverage containing polygons derived from the thiessen polygons of the TIN.
TIN Contours → Arcs
Creates a new coverage containing feature arcs derived from the linear contours displayed on the TIN.
Vertex Strings → Arcs
Creates a new coverage containing a feature arc derived from the vertex string on the TIN (if one exists).
Vertex Strings → Extruded Solid
Creates a new solid from each of the selected TINs by extruding each of the TINs up or down to an elevation specified by the user. Extruded TINs are useful in the construction of solid models of soil stratigraphy.
Fill Between TINs → Solid
Creates a solid by extruding one or more TINs to a base elevation and then performing a set operation to remove the solid portions outside the TINs.
Add Breakline(s)
Inserts edges into the TIN from a defined breakline, splitting or swapping triangles as necessary.
Select Boundary Triangles
Selects triangles on the outer boundary which meet the "long and thin" criteria specified in TIN settings.
Snap Vertices to TIN
Given some selected vertices, moves them so that they are on the surface of a TIN selected from a dialog.
Intersect TINs
Displays the intersection line between two selected TIN surfaces (if they intersect).
Horizons → HUF
Opens the Horizons → HUF wizard to create MODFLOW HUF data from TINs and boreholes. TINs or boreholes with horizon data defined are required, along with a MODFLOW simulation which uses the HUF package.
