Flex - Examples
Flex features are useful for modifying complex models with predictable,
intuitive tools for many applications including concepts, mechanical design,
industrial design, stamping dies, molds, and so on. Flex features can
change single body or multibody parts.
Flex types include:
Bending
Twisting
Tapering
Stretching
For more information about flex feature options, see Flex - Overview and Options.
To modify models using the flex feature:
Click Flex 
on the Features toolbar, or click Insert,
Features, Flex.
In the PropertyManager, under Flex
Input, select bodies in the graphics area for Bodies
for Flex 
.
Select a flex type:
Bending.
Alters bodies around a bend line that corresponds to the X-axis (red arrow)
of the triad, using the position of the two trim planes to determine the
region of flex. This flex type can be used for many applications including
industrial design, mechanical design, solving spring-back conditions in
metal stamping, removing undercuts from complex surface shapes, and so
on.
The neutral plane of the
bend passes through the triad origin and corresponds to the triad’s X-Z
plane. The arc length between the trim planes along the neutral plane
stays constant throughout the bending operation.

Under Flex Options,
move the Flex accuracy 
slider to control surface quality. Increasing the quality
also increases the success rate of the flex feature. For example, if you
get an error message, move the slider towards the right. Move the slider
only as needed; increasing surface accuracy decreases performance.
