pymel.core.modeling.duplicateCurve

duplicateCurve(*args, **kwargs)

The duplicateCurve command takes a curve on a surface and and returns the 3D curve. The curve on a surface could be isoparam component, trimmed edge or curve on surface object.

Flags:

Long name (short name)		Argument Types	Properties
caching (cch)		bool
constructionHistory (ch)		bool
	Turn the construction history on or off (where applicable)
local (l)		bool
	Copy the transform of the surface and connect to the local space version instead.
maxValue (max)		float
mergeItems (mi)		bool
minValue (min)		float
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.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
nodeState (nds)		int
object (o)		bool
	Create the result, or just the dependency node (where applicable)
range (rn)		bool
	Force a curve range on complete input curve (where applicable)
relative (r)		bool

Derived from mel command maya.cmds.duplicateCurve

Example:

import pymel.core as pm

pm.cone( ch=True, o=True, po=0, ax=(0, 1, 0), r=3, hr=4 )
# Result: [nt.Transform(u'nurbsCone1'), nt.MakeNurbCone(u'makeNurbCone1')] #

# duplicate isoparm at v param 0.5 with history
pm.duplicateCurve( 'nurbsCone1.v[0.5]', ch= True, o=True )
# Result: [u'duplicatedCurve1', u'curveFromSurfaceIso1'] #

# duplicate isoparm at normalized u param 0.1, no history
pm.duplicateCurve( 'nurbsCone1.un[0.1]', ch=False )
# Result: [u'duplicatedCurve2'] #

pm.nurbsPlane( ch=True, o=True, po=0, ax=(0, 1, 0), w=10, lr=1 ) ;
pm.circle( ch=True, o=True, nr=(0, 1, 0), r=4 ) ;
pm.projectCurve( 'nurbsCircle1', 'nurbsPlane1', ch=False, rn=False, un=False, tol=0.01 )
# Result: [nt.CurveVarGroup(u'nurbsPlaneShape1->projectionCurve1')] #
# duplicate curve on surface
pm.duplicateCurve( 'nurbsPlaneShape1-"projectionCurve1_1', ch=True, o=False )

pm.trim( 'nurbsPlaneShape1', 'projectionCurve1_Shape1', ch=True, o=True, rpo=True, lu=0.2, lv=0.3 )
# duplicate trim edge
pm.duplicateCurve( 'nurbsPlane1.edge[1][1][1]', ch=True, o=False);
