Arbortext IsoDraw allows you to work with different object types. An object type could be called spare part or assembly. Such object types need to be defined before you can use them. More information on this subject can be found in Select DTD.

The default object type in Arbortext IsoDraw is known as Graphical object. If you have used the Select DTD command on the Objects menu to select a definition file supporting several object types, you can select these from this pop-up menu. When choosing the object type, other entry fields may be visible in the dialog box.
