Knuckles are used in shipbuilding to create flanges that are welded to other, contoured structures in a ship. To save labor time and reduce errors, HGG created a knuckle marking macro.

A part can contain one or more knuckles. They can be located anywhere, as long as it’s not at the beginning and end of the part. The knuckle macro marks the area where the part should be bent. It contains a text label indicating bending direction, length and radius.
