You can use the shortening functionality in the model to make the part longer or shorter in the drawing than in the model. You can shorten and lengthen parts also in drawing views.

Lengthening can be useful for adding length to concrete precast parts in the cast condition while the model stays in the erected state. The most common use for this is to account for pre-stressing elastic shortening, where the part actually shrinks a fraction of an inch after casting and after the strands are cut.
