After a drawing has been added to a project, open it from the Projects collection in the Prospector tree.
If you want to open a project drawing and edit it, you must first check it out. If you do not have the project drawing checked out, you can only open it in read-only mode.
You can tell whether the drawing is checked out to you by the icon displayed next to the drawing name in the Prospector tree. For more information, see Project Item State Icons.
If the drawing you want to check out is a source drawing for a project object, you can open it from the project object collection. For more information, see Opening Source Drawings for Project Objects.
