What Is It? 

A length Nudge lets you manually borrow from or add to middle lengths in a tube shape to lengthen or shorten end lengths. This option can be found in the Bender Setup tab. 

Why is Length Nudge Useful?

Why is this helpful? Nudges help you solve the problem of a pre-cut batch of tubes that are too short or too long, and you cannot scrap or adjust the already-cut tubes.

• Then your goal is to borrow from or add to the straight lengths using small distance adjustments to bring the end lengths close to the correct length.
   
• For example, your tube, after bending, is 1 mm short on End B.  With Nudge, it is possible to borrow some of the lengths in the middle straights to add some of that missing 1 mm from End B.
   
• If, for example, your tube has 12 straights, then you can borrow 0.1 mm from the 10 middle straights to lengthen end B.

Kinds of Length Nudges

There are three kinds of nudges.

1. Nudge with a multiplier - like 0.01 x every Length Adjustment.
2. Nudge with an addition - like add or subtract 0.1 mm to every Length Adjustment.
3. Nudge with a distribution - like distribute 1 mm amongst all the inner straight length adjustment values.

Length Nudge Filters

Also, there are nudge filters:

1. Include or ignore end lengths
2. Nudge only positive lengths
3. Nudge only negative lengths

Extensive Length Nudge Help Included

The Nudge menu includes extensive built-in help menus that explain each Nudge use and Nudge rule.

Nudge Configuration is Per Bender Channel and Global

The Nudge values are stored uniquely for each bender channel and are available for all projects for each bender.
