Flow along Surface

 History enabled

The FlowAlongSrf command morphs objects from a source surface to a target surface.

Steps

  1. Select objects.
  2. Select the edge of the base surface near a corner.
  3. Select the edge of the target surface near a matching corner.

Command-line options

Copy

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

Decides if objects are only relocated, but not deformed, along the target surface.

Blue boxes as the input objects.
Yes

Only relocates the objects.
No

Relocates and deforms the objects.
RigidGroups

Decides using groups or individual objects to rigid. Only available when Rigid=Yes.

Four groups of boxes as the input objects.
Yes

Rigids with groups.
No

Rigids with individual objects. Groups are ignored.
Plane

Draw a plane instead of using an existing surface as the base objects.

See the Rectangle command for detailed option descriptions.

ConstrainNormal
Yes

Maps the objects onto the target surface while maintaining the orientation relative to the construction plane normal of the viewport in which the target surface is selected.

No

Maps the objects onto the target surface using the target surface normal direction.

AutoAdjust
Yes

UVN directions defined by the picking location on the surface.

The object may be mapped onto the opposite side of the target surface if the picking locations on the base and target surfaces don't match.

No

A trimmed surface (left), its underlying surface (middle) and the shrunk surface (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).
