This option can be used to represent segments or lines in annotation elements by equally spaced symbols 'over' the segments or the lines (see examples below).

When you use this option for segments classes (representation class), you can specify symbol type, symbol, symbol size and rotation for each class of segments.

Tips:

To use for instance a Corel Draw symbol font, first make sure that the font is registered by Windows:

In the Windows Settings, choose Control Panel, and choose Fonts. A list of installed fonts will appear.
When the desired symbol fonts are not yet in this list, choose File, Install New Font. The Add Font dialog box will appear.
Specify the Corel Draw/Symbols directory, select the fonts you want to use and click OK.

Now that the symbol fonts are registered by Windows, you can use them in ILWIS as well.
