Amplify—Changes the scale factor applied to the
minor axes. Amplify generates a multiplier u sing
thesametechniqueasstretch. Themultiplieris
then applied to the Stretch value before the scale
factorfortheminoraxesiscalculated.
Amplify values affect scaling along the minor axes
in the following way:
• A value of 0 has no effect. It uses the default
scale factor calculated from the Stretch amount.
• Positive values exaggerate the effect.
• Negative values reduce the effect.
Stretched objects with Amplify values of 0.0, 1.0, and
-1.0.
Stretch Axis group
You select w hich of the object’s loca l axes is the
Stretch Axis using options in the Stretch Axis
group of the Parameters rollout.
• The scale factor calculated from the Stretch
Amount is applied to the Stretch Axis.
• The inverse sc ale factor is applied to the
remaining minor axes.

Limits group
You can apply the stretch effect to t he entire object,

intheLimitsgroupoftheParametersrollout.The
limits restrict the st retch effect along the positive
and negative Stretch Axis as measured f rom the
modifier’s center.
Limit Ef fect—Limits the stretch effect. When Limit
Effect is turned off, values in the Upper an d Lower
Limit fields are ignored.
Upper Limit—Sets the b oundary of the stretch
effect along t he pos itive Stretch Axis. The Upper
Limit can be 0 or any positive number.
Lower Limit—Sets the b oundary of the stretch
effect along the negative Stretch Axis. The Lower
Limit can be 0 or any negative number.
