Extending product function with VBA : The System Architect object model : Object model classes : Symbol class : Symbol class: Methods : SetProperty
  
SetProperty
By knowing the property name and its value, you can set a property of a symbol. Examine usrprops.txt and saprops.cfg for a complete list of all property names.
Parameters
Often the real name of a property is not the same as what shows up on a definition dialog; for example, in a Junction of a IDEF3 Process Flow/ OV-6a diagram, the Logic property is actually a rename; the real property is Junction Logic. You would only know this if you looked up the definition of a Junction in saprops.cfg and saw that the property is actually called Junction Logic but has been labeled Logic:
PROPERTY "Junction Logic" { EDIT Text ListOnly LIST "Junction Logic" LENGTH 3 DEFAULT "And" LABEL "Logic" }
