Specifies a numeric help ID for a property name or module type.
Each help topic exists in a separate help file. The software opens the [Smart3DInstallDirectory]\Documentation\HTML\HELP_ID.htm file and locates the correct help file. HELP_ID is the number defined in the schema for this module type or property. When you click a property name or module type in the Rule Manager, the related help topic displays in the Information pane on the right.
HELP_ID exists as a child node under the PROPERTY node:
<PROPERTY NAME="PropertyName">
<HELP_ID>123456</HELP_ID>
If a user-defined property does not have a corresponding HELP_ID, or if the software
does not find a help file, a Help File is Missing message displays in the Information pane.
