Synopsis

reverseSurface [-constructionHistory boolean] [-curveOnSurface boolean] [-direction int] [-name string] [-object boolean] [-polygon int] [-range boolean] [-rebuild boolean] [-replaceOriginal boolean] [surfaceName]

reverseSurface is undoable, queryable, and editable.

The reverseSurface command reverses one or both directions of a surface or can be used to "swap" the U and V directions (this creates the effect of reversing the surface normal). The name of the newly reversed surface and the name of the resulting dependency node is returned. The resulting surface has the same parameter ranges as the original surface.

This command also handles selected surface isoparms. For a selected isoparm, imagine that the isoparm curve is reversed after the operation. eg. reverseSurface surface.v[0.1] will reverse in the U direction.

Flags

constructionHistory, curveOnSurface, direction, name, object, polygon, range, rebuild, replaceOriginal
Long name (short name) [argument types] Properties
-direction(-d) int queryedit
The direction to reverse the surface in: 0 - U, 1 - V, 2 - Both U and V, 3 - Swap
Default: 0

In query mode, this flag needs a value.
-name(-n) string create
Name the resulting object
-constructionHistory(-ch) boolean create
Turn the construction history on or off (not available in all commands)
-object(-o) boolean create
Create the result, or just the dependency node (not available in all commands)
-replaceOriginal(-rpo) boolean create
Create "in place" (i.e., replace) (not available in all commands)
-curveOnSurface(-cos) boolean create
If possible, create 2D curve as a result (not available in all commands)
-polygon(-po) int create
The value of this argument controls the type of the object created by this operation (not available in all commands)
  • 0: nurbs surface
  • 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)
  • 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)
  • 3: Bezier surface
  • 4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
-range(-rn) boolean create
Force a curve range on complete input curve (not available in all commands)
-rebuild(-rb) boolean create
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion. (not available in all commands)
Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can be used more than once in a command

Return value


[string[]] (object name and node name)

MEL examples

reverseSurface -ch on -d 0 surface1;
reverseSurface -ch on surface1.v[0.1];
// Reverses surface1 with construction history in the U direction.
// The name of the new surface and the name of the new dependency node
// are returned.

reverseSurface -ch off -rpo on -d 1 surface1;
reverseSurface -ch on surface1.u[0.1];
// Reverses surface1 without history, with replace original on,
// in the V direction.  Because the "-rpo" flag is on, the name of
// the original surface is returned as well as the new dependency node.
// The reversed surface will <em>replace</em> the original surface.

reverseSurface -ch off -rpo on -d 2 surface1;
// Reverses surface1 without history, with replace original on,
// in both the U and V directions.

reverseSurface -ch off -rpo on -d 3 surface1;
// Swaps the U and V directions of surface1 with history, with replace
// original on.  This has the effect of reversing the surface normal.
