Change Hatch
Wireframe
To process a single wireframe, select the Single option, select the Type of the wireframe, and then the Name of a wireframe of that type.
To process multiple wireframes, expressions, wildcards and partial names may be used in the Name field to select multiple wireframes as an adhoc wireframe set. A right-click Preview option will perform a check of an expression before using that expression to generate an updated list of wireframes. Alternatively, you can click the Expression icon 
and use the Expression Editor to create, modify and validate the expression. When a name or wildcard is entered in the Name field, and the Expression button is selected, the name/wildcard will automatically be converted to a valid expression when opened in the editor.
To process the wireframes in a predefined wireframe set, select the Set option.
It is recommended that you Validate wireframes prior to using them in any process.
Copy Hatch From Template
Select this option to nominate an existing wireframe as a template and copy the hatch definition from that wireframe.
Select the Type and then the Name of the template wireframe.

A 2D Slice and Silhouette hatch pattern can be saved as part of the wireframe. When displaying a wireframe, select Default Hatch to use these saved hatches. This can be particularly handy when displaying a wireframe set.
The default hatch (silhouette and slice) for any wireframe is NO FILL, with a solid, 0.20mm thick border using the wireframe colour. This default hatch is indicated by the NULL patch, in either the Property Pane (select the wireframe in Vizex) or the Wireframe Properties (right click on the Wireframe Name in any form).
See: Hatch
There is a subtle distinction between a wireframe displayed in 2D Slice mode and a wireframe displayed in Silhouette mode. Silhouette mode always generates one or more polygons (closed strings), whereas 2D Slice mode may generate profiles (from open surfaces) and/or polygons (from closed surfaces or solids).
- 2D Slice display settings comprise a fill pattern (ignored when the wireframe is an open surface) and line style options (used to draw the profile when the wireframe is an open surface, and used to draw the border when the wireframe is a closed surface).
To clarify that border line options are defined separately, the Border group box has been removed from the Fill pattern dialog.
Fill pattern
Double-click on the Hatch icon to select a Select a hatch for a Silhouette, or for the 2D slice of a wireframe solid.
Line type
Select a line type. A preview of each line type is shown in the drop-down list. A variety of solid, dotted, and dashed line styles are available for selection.
Line width
Select a (THIN, MEDIUM, THICK, or custom) line width from the drop-down list. An extensive selection of custom widths (in millimetres) are also available for selection.
Line Colour
Choose how the lines are coloured:
| From Wireframe | Use the wireframe colour |
| From Pattern | Use the foreground colour |
| User | Enable the colour picker to the right of the drop-down list |
Silhouette
For a silhouette, line type, line width and line colour selections define the border style of the wireframe (or the profile line style for open surfaces).
In the case of a 2D Slice, line type, line width and line colour selections are exposed to allow the profile line style for open surfaces to be defined without selecting a fill pattern
Fill Pattern
Double-click on the Hatch icon to select a default Select a hatch.
Use wireframe colour for the border
Select this option to apply the wireframe colour to the silhouette border.

Since you might want to use the advanced options for 2D Slice and not Silhouette (or vice-versa), or for only one of the attributes (say foreground colour), there is provision to define default values for every attribute of the hatch.
Any option that is not selected, will be defined by the appropriate parameters on the main form. For example, if the Pattern option is not selected, then the pattern defined on the main form will be used.

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.
