Display

On the Display tab of the Polygonal Model form, set display options for the polygons and the links that will be displayed in Vizex.

Line Style

Line sets give you the ability to apply different line styles and line widths to the polylines in a single dataset. You can apply them in the same way that you can apply colours, hatches and symbols to your data.

Line field

Double-click (F3) to select the name of a field that will be matched to the code values in a Line set.

Line set

If you have specified a Line field, double click (F3) to select the set that will be used to control the style and the width of the polylines in the dataset.

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 available for selection.

Colour Coding

Colour field

Specify the name of a field which contains the values that will be used to colour-code the display.

You can choose to select colour values directly from the Colour field without selecting a Colour set. In this case, the values in the Colour field must be valid RGB, Hex, or Integer colour definitions.

Format	Example
R,G,B	89,169,215
HTML Hex	#59A9D7
Hex	0x59a9d7
int	5876183

Colour set

To map values in the Colour field to the colour values in a Colour set, double click (F3) to select the set that will be used to control the display colour. Right-click (F4) to create or edit a Colour set.

Colour

Double-click (F3) to select the colour that will be used when a Colour field or a Colour set is not defined - or when a value in the Colour field is either not valid or is not mapped in the Colour set.

Fill Polygons

Select this option if you want to apply a hatching to the polygons in the display.

Hatch field

Enter the name of the field (in the file) containing the data that will control the hatching. The hatch set associated with this field maps hatch patterns to text strings or numeric ranges. For each record in the file, the hatch pattern to be used is determined by the value in this field.

Hatch set

Double click (F3) to select the set that will be used to control the hatch pattern. The hatch set maps hatch patterns to text strings or numeric ranges. This determines the hatch pattern for each value in the hatch field. Right click (F4) to create or edit a hatch set.

Hatch

Double click (F3) to select the hatch which will be used when a hatch set is not defined, or when the value in the hatch field is not mapped in the hatch set.

Linked Polygons

Link line colour

Double click (F3) to select the colour to be used for the polygon link lines.

Polygon Centroid Symbol

The polygon centroid symbol is shown only for linked polygons along with the link lines. The same symbol is also used when closing to a line or closing to a point to display the centre of the line or the actual closure point.

Double-click the Symbol icon to choose a symbol for the centroids. You can source symbols from any TrueType or OpenType font.

Symbol colour

Double click (F3) to select the colour to be used for the point centroid symbols.

Symbol Size factor

Enter a size factor for the symbols. This will be used when there is no entry in the Size field for that point. The default is 1.0.

Run

Enter parameters in the form, then click Run to run the function.
