Trim Edges

On the Grid / DTM tab, in the DTM Tools group: Click Trim Edges to select an input surface DTM and trim the edges, where those edges are over-length or have narrow angles.

Input DTM

Select the type of the wireframe, typically DTM, and then enter (or double-click to select) the name of the wireframe that will be used as input to the Trim process.

Trim Edges

To trim the edges of the input DTM where those edges are over-length or have narrow angles, specify either or both of the following values:

Minimum Angle

The edges of the triangulation which are less than the specified Minimum angle are deemed invalid and are trimmed.

Maximum Length

The edges of the triangulation which are longer than the specified Maximum length are deemed invalid and are trimmed.

Output DTM

Select the Overwrite input DTM option if you want the result of the process to be applied to the Input DTM. If this option is selected, the following Output prompts will be disabled:

Type and Name

Specify the type and name of the Output DTM.

Colour

Specify a default display colour for the Output DTM.

Attributes

Click the Attributes button to set Wireframe Attributes for the wireframe 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 output in Vizex. The default draw style for an auto-loaded wireframe is 3D Shaded.

Forms

Click the Forms button to select and open a saved form set, or if a form set has been loaded, save the current form set.

By design, the Forms button is not available for loaded Vizex layers (i.e. when opening the form set properties of a layer in the Vizex Layer Display pane). In Vizex, the Forms button is only available for new forms opened via the Home tab or the Vizex tab, in the Layer group (or by double-clicking on a form type node in the Vizex Layer Types pane).

Save and Save As

Click the Save button to save the changes you have made to the form set. Click Save As to save your changes as a new form set. Save As will default to the first available form set number.

Reset

Click Reset to clear the form of all values and reset the form to its default state.

Reset Tab

For tabbed forms, select Reset Tab to clear the active tab of all values and reset the tab to its default state - without making any changes to other tabs in the dialog.

Undo and Redo

Click Undo (CTRL + Z) to undo recent changes in the form. After an Undo, click Redo (CTRL + Y) to restore the last change that was undone.

Collapse

Collapse (roll-up) the form to preview a chart, or preview the results of an operation in Vizex, or obtain input values from Vizex, the Property Window, the File Editor, or the Plot Editor.

Run

Finally, click Run to begin the process.
