You can only use this option if there is an AutoCAD/GENIUS drawing frame in the drawing.

In previous AutoCAD versions, the entire drawing was processed when item numbers were evaluated for the BOM. Now, it is also possible to evaluate a drawing frame (i.e. all item numbers within the frame in question).

If the drawing contains several drawing frames, you can choose the "Select drawing frame" option to select the drawing frame whose item numbers you wish to evaluate.
