Grid to DTM

On the Grid / DTM tab, in the Grid Convert group: Click To DTM to convert a Micromine Grid Surface file to a Micromine DTM file. Use this function when you want to display a Grid Surface file as a Contour layer in Vizex. While preserving the topology of the DTM, the conversion process takes into account the trend in the data when choosing which diagonal to put the triangles on.

An option to sub-sample the grid before conversion is provided. This allows the 1, 2, 3, 4, 5th, etc point to be used.

Input

On the Input tab of the Grid to DTM form, double-click (F3) to select the name of the Grid file that will be converted to a DTM.

Sample every nth block

To sub-sample the grid before conversion, define the number of X and Y cells that will be used to create the X and Y range of the triangulated surface. Increasing the sampling interval will reduce the amount of memory required to generate a DTM. However, a simpler DTM will be produced as a result.

Output

Type

Select an output wireframe type. DTM is the default output type for this process.

Name

Enter (or click on the Select icon to select) the name of the DTM to be created.

Code

Optionally enter a code that can be used to differentiate between the different outputs generated as a result of the process.

Colour

Optionally double click (F3) to select a default display colour for the output DTM.

Title

Optionally enter a Title that is descriptive of the generated output.

Attributes

Click the Attributes button to set attributes for the DTM output.

User Defined Attributes may be mapped against the fields in the Input file. It is also possible to specify a default value for each attribute. Default values are used when a corresponding value in the Input file is either missing or is not mapped.

Auto load

Select this option to load the generated DTM in Vizex. The default draw style for an auto-loaded wireframe is 3D Shaded.

Run

Finally, click Run to generate the Output DTM.
