Weldment Drawings
Drawings of weldments support:

Balloons in Weldment Drawings
All configurations reference the same cut list for creating balloons.
Balloon
numbers remain associative to the cut list, even if they are created in
another view. A
balloon attached to a body in a drawing view of the entire weldment and
a balloon attached to the same body in a drawing view showing only the
body have the same item number.
If you insert AutoBalloons into a drawing view of a weldment and the
drawing does not contain a cut list, you are prompted whether you want
to create a cut list.
If you delete a cut list, all balloons related to the cut list change
their Item Number to 1.
