Transform Flow along Curve |
The Flow command re-aligns an object or group of objects from a base curve to a target curve.
Use the Flow command to map a flat, straight shape to a curved shape, since it can be easier to draw things when they are lined up than to draw a complex shape around a curve.
Command-line options
Uses a surface to orient objects. The "up" direction of the objects will be mapped to the surface normal.

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.
Decides if objects are only relocated, but not deformed, along the target curve.
Decides using groups or individual objects to rigid. Only available when Rigid=Yes.
Draw a line to be used as the base curve.
Specify circles to define a "tube" of influence around the input curve. Everything inside the tube flows. Everything outside the tube is fixed. Inside the tube wall the flow dies off.
Decides to stretch or compress objects in the curve direction so that the relationship to the target curve is the same as it is to the base curve.
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.
Uses frames (x, y, z axes) to calculate 3-D rotation when objects flow to the target curve.
Pick the roadlike axis base point and direction on the base curve.
Pick the roadlike axis base point and direction on the target curve.
