You can control the visibility of Frames and Frame Names using the Structure visibility dialog or the Frame icon on the Visibility toolbar.
You can also modify some Frame properties numerically in the Frame table of the Data window.
Frames appear in the list of parts in the Part table in the Data window.
Individual frames may be shown or hidden. This is done by right-clicking on the part in the assembly tree view, and choosing Show or Hide from the pop-up menu, or by changing the check box in the Visibility column in the Data window.
