Bend Modeling
When designing parts with bends where the parts must fit together, it is important to verify, on screen,
that parts fit properly, that holes align, etc. The Model Bends command helps you do so. The command creates a realistic side view drawing of the bends which can then be used to check fit.

The Model Bends command considers the
sheet thickness, bend radius, and the compression and expansion of
material that occurs at a bend.
For mating parts, slide the side
views on screen (and rotate if needed) to see if parts mate properly. Mating
should have some play since the position and radius of each bend and the CAD bend
model cannot be achieved with zero error. For new or changed complex designs it
is recommended to do a short run initially.
