Select the object to be removed from a form, and on the Edit menu or the context menu, click Delete.
Note: When an object is removed from a form and has been bound to an attribute, the attribute is not deleted from the Model unless the following steps are taken.
To remove an object and delete the attribute, perform the following:
If it is not already open, open the Class View window by clicking the View, Class View menu item.
Sort the hierarchical list into the most appropriate form to locate the attribute you want to keep.
If necessary, click the plus (+) symbol next to a node to list all the items within the node.
Select the attribute you want to delete.
In the Property window, select the Direction property.
Set the property to None.
This removes the object from the form in the Painter window and deletes the attribute.
