GMS:TIN Commands

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.

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 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.

Advanced...

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).

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.

Z Values → Dataset

Creates a dataset from the Z locations of the vertices.

Map to Z Values

Moves the Z locations of the vertices to the values in the dataset.

Zoom To Extents

Frames the Graphics Window around the selected objects.
