UML Rules

A Rules Check is provided for all UML diagrams. It may be run by selecting Unified Rules Check from the Reports menu on any of the UML diagrams. System Architect runs a rules check and places visual indications (circles enclosing the number of the error or warning) on the diagram where UML notation and semantic rules have been violated. The visual indicators may be removed by selecting Clear Errors on the Reports menu.

The rules check may be customized by the user, by editing the UFMRULES.BAS, UFMRULE1.BAS, and UFMRULE3.BAS files (UFM for Unified Method), located in the same directory as the System Architect executable (generally Program Files\System Architect). Customization of the rules check is for advanced users only.
