To open an existing assembly project, either click on the Open Project button in the right toolbar, or click on the “Open an Assembly Project” text button in the Quick Start column. This displays a dialog (Figure 3) in which you can select the name and specify the directory location of the project to be opened. By default, only 454 Assembly Projects will be displayed. You may choose to display all files by selecting “All Files” from the “Files of Type” dropdown menu.
