Holes, Notches and Cutouts in Profiles

In addition to the end cut definition holes, notches and cutouts can be set in the interior of the profile. However, this facility is restricted to stiffeners, that means, no holes can be set in flanges and pillars.

The generation of holes in stiffeners is done in a similar way as for plates. Special variants of the HOLE, NOTCH and CUTOUT statements are used for this purpose. See these statement types for further information.

Normally when an item in a panel is generated there is a one-to-one or one-to-many relation between the input statement and the component(s) that it generates, that means, normally all information in a certain component has its origin in one statement. (Exception: The outer contour which may be modified by a folded flange.)

However, in stiffeners with holes, the stiffener itself is generated by one statement and the holes may be generated by several other statements. This must be taken into consideration when stiffeners are regenerated/changed/deleted. Then, in some cases, several different statements may have to be modified or rerun. However, in each situation the system tries to take the most natural action. In any case, as soon as a stiffener with holes in regenerated, a warning message will be issued.
