pymel.core.modeling.polyCut¶

polyCut(*args, **kwargs)¶

This command splits a mesh, or a set of poly faces, along a plane. The position and orientation of the plane can be adjusted using the appropriate flags listed above. In addition, the cut operation can also delete the faces lying on one side of the cutting plane, or extract those faces by an offset amount.

Flags:

Long Name / Short Name		Argument Types	Properties
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed.
constructionHistory / ch		bool
	Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note:If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.
cutPlaneCenter / pc		float, float, float
	This flag specifies the position of the cutting plane.
cutPlaneCenterX / pcx		float
	This flag specifies the X position of the cutting plane.
cutPlaneCenterY / pcy		float
	This flag specifies the Y position of the cutting plane.
cutPlaneCenterZ / pcz		float
	This flag specifies the Z position of the cutting plane.
cutPlaneHeight / ph		float
	This flag specifies the height of the cutting plane. This is used only for displaying the manipulator, and has no effect on the cut operation.
cutPlaneRotate / ro		float, float, float
	This flag specifies the orientation of the cutting plane.
cutPlaneRotateX / rx		float
	This flag specifies the X rotation of the cutting plane.
cutPlaneRotateY / ry		float
	This flag specifies the Y rotation of the cutting plane.
cutPlaneRotateZ / rz		float
	This flag specifies the Z rotation of the cutting plane.
cutPlaneSize / ps		float, float
	This flag specifies the size of the cutting plane. This is used only for displaying the manipulator, and has no effect on the cut operation.
cutPlaneWidth / pw		float
	This flag specifies the width of the cutting plane. This is used only for displaying the manipulator, and has no effect on the cut operation.
cuttingDirection / cd		unicode
	This flag specifies the direction of the cutting plane. Valid values are x, y, zA value of xwill cut the object along the YZ plane cutting through the center of the bounding box. A value of ywill cut the object along the ZX plane cutting through the center of the bounding box. A value of zwill cut the object along the XY plane cutting through the center of the bounding box.
deleteFaces / df		bool
	This flag specifies if the cut faces should be deleted or not.
extractFaces / ef		bool
	This flag specifies if the cut faces should be extracted or not.
extractOffset / eo		float, float, float
	This flag specifies the offset by which the cut faces will be extracted. This flag has no effect when the extractFacesis turned off.
extractOffsetX / eox		float
	This flag specifies the offset in X by which the cut faces will be extracted. This flag has no effect when the extractFacesis turned off.
extractOffsetY / eoy		float
	This flag specifies the offset in Y by which the cut faces will be extracted. This flag has no effect when the extractFacesis turned off.
extractOffsetZ / eoz		float
	This flag specifies the offset in Z by which the cut faces will be extracted. This flag has no effect when the extractFacesis turned off.
frozen / fzn		bool
name / n		unicode
	Give a name to the resulting node.
nodeState / nds		int
	Defines how to evaluate the node. 0: Normal1: PassThrough2: Blocking3: Internally disabled. Will return to Normal state when enabled4: Internally disabled. Will return to PassThrough state when enabled5: Internally disabled. Will return to Blocking state when enabledFlag can have multiple arguments, passed either as a tuple or a list.
onObject / oo		bool
worldSpace / ws		bool
	This flag is ignored. polyCut command always works on worldSpace. Common flags

Derived from mel command maya.cmds.polyCut

Example:

import pymel.core as pm

# Introduce new edges at the middle of a cylinder
#
pm.polyCylinder( r=1, h=2, sx=20, sy=1, sz=1, ax=(0, 1, 0), cuv=1, ch=1, name='pCylA' )
pm.polyCut( 'pCylA.f[0:59]', cd='Y', ch=1 )

# Delete the bottom half of the cylinder
#
pm.select( cl=True )
pm.polyCylinder( r=1, h=2, sx=20, sy=1, sz=1, ax=(0, 1, 0), cuv=1, ch=1, name='pCylB' )
pm.move( 3, 0, 0, r=True )
pm.polyCut( 'pCylB.f[0:59]', cd='Y', df=1, ch=1 )
pm.select( cl=True )


# Split the bottom half of the cylinder
#
pm.select( cl=True )
pm.polyCylinder( r=1, h=2, sx=20, sy=1, sz=1, ax=(0, 1, 0), cuv=1, ch=1, name='pCylC' )
pm.move( 6, 0, 0, r=True )
pm.polyCut( 'pCylC.f[0:59]', cd='Y', ef=1, ch=1 )

# select one of the cylinders, and select the polyCut node from the
# channel box, and enter the showManipulator Tool, on the Toolbar.
# You can interactively place the cutting plane, and the result of
# cut operation will adjust accordingly.
