Using twist to deform the lofted roadway

These are the properties of Twist deformation

cur ves:

• A single red curve determines shape rotation

about the path.

• The default curve value is 0 degrees of rotation.

• Positive values produce counterclockwise

rotation, when viewed from the start of the

path.

• Negative values produce clockwise rotation.

•Bothtwistdeformationandbankingproduce

rotation about the path. Tw ist rotation is added

to a shape after the banking angle is applied.

You can use Twist deformation to exaggerate or

reduce the amount of banking.

See

Deformation Dialog (p age 1–363)

for specific

information on the dialog controls.

Procedure

To use Twist deformation:

Select a loft object.

2. Click Loft in the modifier stack display.

3. Click Twist on the Deformations rollout.

4. Editthesingledeformationcurvetospecify

rotation about the path.

Def or m Teet er

Select a Loft object. > Modify panel > Deformations

rollout > Teeter

Teeter deformation rotates shapes about their loc al

X axis and Y axis. Teetering is what 3ds Max does

automatically when you select Contour on the Skin

Parameters rollout. Use Teeter deformation when

you want to manually control contour effects.
