pymel.core.modeling.reverseCurve¶

reverseCurve(*args, **kwargs)¶

The reverseCurve command reverses the direction of a curve or curve-on-surface. A string is returned containing the pathname of the newly reversed curve and the name of the resulting dependency node. The reversed curve has the same parameter range as the original curve.

Flags:

Long Name / Short Name		Argument Types	Properties
caching / cch		bool
	Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
constructionHistory / ch		bool
	Turn the construction history on or off.
curveOnSurface / cos		bool
	If possible, create 2D curve as a result.
frozen / fzn		bool
name / n		unicode
	Sets the name of the newly-created node. If it contains namespace path, the new node will be created under the specified namespace; if the namespace does not exist, it will be created.
noChanges / nc		bool
nodeState / nds		int
	Modifies the node state. See the node documentation for more information. Note:For advanced users only. Flag can have multiple arguments, passed either as a tuple or a list.
object / o		bool
	Create the result, or just the dependency node.
range / rn		bool
	Force a curve range on complete input curve.
replaceOriginal / rpo		bool
	Create in place(i.e., replace). Advanced flags

Derived from mel command maya.cmds.reverseCurve

Example:

import pymel.core as pm

pm.reverseCurve( 'curve1', constructionHistory=True )
# Reverses curve1 with construction history on.  The result will
# be a string array, where the first string is the name of the new
# reversed curve and the second string is the name of the new
# dependency node.

pm.reverseCurve( 'curve1', ch=False, replaceOriginal=True )
# Reverses curve1 without construction history, replacing the original.
# The result will be a string array, where the first string
# is the name of the curve (curve1).  Because history is off,
# no dependency node will be created.  The reversed curve will
# replace the original curve.

pm.reverseCurve( 'curve1', ch=True, rpo=True )
# Reverses curve1 with history, trying to replace the original.
# If curve1 was not a result of construction history, then this command
# will simply replace curve1 with the reversed curve.  No dependency
# node will be created.

# If curve1 was a result of construction history, then this command
# will insert a reverse dependency node before the curve.  eg.
# Before reverseCurve cmd:   curve0 ---" closeCurve DN ---" curve1
# After cmd:  curve0 ---" closeCurve DN ---" reverseCurve DN ---" curve1

# The result will be a string array , where the first string
# is the name of the curve (curve1) and the second name is the
# new dependency node.
