You can edit the physical make-up of an element as well as its dimensions by accessing the element’s Basic property page. Some elements have additional property pages that control its composition. For example, cabinets have Leaf and Details property pages.
When you edit the properties of elements that exist in your drawing, only selected elements are changed. Other occurrences of the element in your drawing remain unchanged. You can, however, select and edit multiple elements at the same time provided they share the same properties.
To edit the properties of an inserted element:
Access the element's properties.
Adjust the properties as desired. Clicking a dimension marked with an alphabetical character (a, b, c, etc.) highlights the corresponding dimension in the element graphic, and vice versa, if one exists.
Click OK. The selected elements are updated in the drawing.
Note: Editing the properties of an element in your drawing has no effect on the element’s property definition in the catalog it came from. If you want to edit an element in a catalog, see Editing Elements in a Catalog. Editing an element in a catalog affects all future insertions of that element in your drawing.
