Edit Page
From the Modeler Home Page
select an existing model or click on New 
.
Modeler will switch to this page showing
a system of dockable editing windows.
The first view will be of the model's class diagram displayed in the
Class Diagram Window.
For new models the window is empty.
Be sure to save modifications with Save 
before leaving the page.
Edit changes can be reverted, one-by-one, using
Undo 
, and reinstated using
Redo 
.
Class Diagram Window
The UML graphical depiction of the model is the
diagram shown in this window.
New classes can be added to a diagram using
New .
Click on the inside edge of a class box and drag to another class
box (or back to the same) to create an association.
Do the same with the Shift key pressed to create a
generalization, or Ctrl key for a dependency.
Class boxes can be dragged around the diagram to reposition them. Relationship lines and adornments will be redrawn automatically.
Use the Properties Window to display and change the selected object's properties. Note that the association end, the line segment directly connected to the class box, can be selected to display the end's properties. An association end shows up as an attribute of the class at the opposite end of the association line.
Explorer Window
A tree-structured view of all the model objects are displayed in this window. Classes are displayed with their attributes and operations. Model relationships are displayed as well.
New and
Delete work on many of the nodes in the Explorer tree.
For example, New can be used to create a new class attribute or operation when the
class's node is selected. To remove a class from the model,
select it and press Delete.
Changes are automatically redisplayed in both the Explorer and the
Class Diagram windows.
Use the Properties Window to display and change the selected node's properties.
Properties Window
The form in this window displays the properties of the object that is selected in the
currently active window. When a selected object does not have properties the window is blank.
To change a property simply type or select the new value and press Enter or click on
form Apply 
(changes made before applying will be discarded without warning if a different object
is seleced).
XML Window
The model's semantics are shown in XML format. All model elements are XML elements. The text can be copied into an external document for additional processing. Current edit data is shown, which will be different from the saved data if there are unsaved changes.
The information in this window is not editable. It is displayed as a modal window which must be closed to continue editing.
