Twist

The Twist command deforms objects by rotating them around an axis.

Steps

  1. Select objects.
  2. Pick the start of the twist axis.
    The part of the object closest to this point will be fully twisted, and the part farthest from it will keep its original orientation.
  3. Pick the end of the twist axis.
  4. Type the angle, or pick two reference points to define the rotation angle.
Command-line options

Copy

 History enabled

Specifies whether or not the objects are copied. A plus sign appears at the cursor when copy mode is on.

The RememberCopyOptions command determines whether the selected option is used as the default.

Rigid

Specifies that individual objects will not be deformed as they are transformed.

The illustration shows the Rigid option with the Bend command.

Yes

Individual objects will not change, only their positions will change.

No

Individual objects are transformed as well as their positions.


Original objects (left), Rigid=No (center), Rigid=Yes (right).

Infinite
Yes

The deformation is constant throughout the object, even if the axis is shorter than the object.

No

The twisting is not constant throughout the object. The deformation takes place only the length of the axis. The length of the axis is important. If the axis is shorter than the object, the twist applies only to that part of the object. In addition, the twist blends in and out at the ends of the axis.


Infinite=Yes (left); Infinite=No (right).

PreserveStructure

Specifies whether the control-point structure of a curve or surface will be maintained after the deformation.

The PreserveStructure option does not apply to polysurfaces, and will not be displayed if polysurfaces are selected for editing.

Yes

The control point structure of the surface is maintained. Deformation may be less accurate if there are too few control points in on the object.

No

The objects are refit as needed with more control points to allow accurate deformation.


PreserveStructure=Yes (left); PreserveStructure=No (right).
