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).
frozen / fzn		bool
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.
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). Flag can have multiple arguments, passed either as a tuple or a list.
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);
