programmatic construction of class models

[plewis]

I want to build an object model from some Forte source code (TOOL language)
and to display the model using a Visio UML template.

I can create class objects and populate their Name field, but when I try to
update the items that contain the Operations or Attributes using the
following statement:

objShape1.Shapes.Item("Operations").Text = "MyOperation()"

I get the message 'Requested operation is presently disabled'.

What is the correct way to do this?

Regards,
