pymel.core.modeling.revolve¶

revolve(*args, **kwargs)¶

This command creates a revolved surface by revolving the given profile curve about an axis. The profile curve can be a curve, curve-on-surface, surface isoparm, or trim edge.

Flags:

Long Name / Short Name		Argument Types	Properties
autoCorrectNormal / acn		bool
	If this is set to true we will attempt to reverse the direction of the axis in case it is necessary to do so for the surface normals to end up pointing to the outside of the object. Default:false
axis / ax		float, float, float
	Revolve axis
axisChoice / aco		int
	Only used for computed axis/pivot case. As we are computing the axis for a planar curve, we have two choices for the major axis based axis. We will choose the axis corresponding to the longer dimension of the object (0), or explicitly choose one or the other (choices 1 and 2). Default:0
axisX / axx		float
	X of the axis Default:1
axisY / axy		float
	Y of the axis Default:0
axisZ / axz		float
	Z of the axis Default:0
bridge / br		bool
	If true, we will close a partial revolve to get a pie shaped surface. The surface will be closed, but not periodic the way it is in the full revolve case. Default:false
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed
computePivotAndAxis / cpa		int
	If this is set to 2, we will compute the axis, use the curve position and radius to compute the pivot for the revolve internally. The value of the pivot and axis attributes are ignored. If this is set to 1, we will take the supplied axis, but compute the pivot. If this is set to 0, we will take both the supplied axis and pivot. Default:0
constructionHistory / ch		bool
	Turn the construction history on or off.
degree / d		int
	The degree of the resulting surface. Default:3
endSweep / esw		float
	The value for the end sweep angle, in the current units. This must be no more than the maximum, 360 degrees, or 2 Pi radians. Default:6.2831853
frozen / fzn		bool
mergeItems / mi		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.
nodeState / nds		int
	Maya dependency nodes have 6 possible states. The Normal (0), HasNoEffect (1), and Blocking (2)states can be used to alter how the graph is evaluated. The Waiting-Normal (3), Waiting-HasNoEffect (4), Waiting-Blocking (5)are for internal use only. They temporarily shut off parts of the graph during interaction (e.g., manipulation). The understanding is that once the operation is done, the state will be reset appropriately, e.g. Waiting-Blockingwill reset back to Blocking. The Normaland Blockingcases apply to all nodes, while HasNoEffectis node specific; many nodes do not support this option. Plug-ins store state in the MPxNode::stateattribute. Anyone can set it or check this attribute. Additional details about each of these 3 states follow. StateDescriptionNormalThe normal node state. This is the default.HasNoEffectThe HasNoEffectoption (a.k.a. pass-through), is used in cases where there is an operation on an input producing an output of the same data type. Nearly all deformers support this state, as do a few other nodes. As stated earlier, it is not supported by all nodes. Its typical to implement support for the HasNoEffectstate in the nodes compute method and to perform appropriate operations. Plug-ins can also support HasNoEffect. The usual implementation of this state is to copy the input directly to the matching output without applying the algorithm in the node. For deformers, applying this state leaves the input geometry undeformed on the output. BlockingThis is implemented in the depend node base class and applies to all nodes. Blockingis applied during the evaluation phase to connections. An evaluation request to a blocked connection will return as failures, causing the destination plug to retain its current value. Dirty propagation is indirectly affected by this state since blocked connections are never cleaned. When a node is set to Blockingthe behavior is supposed to be the same as if all outgoing connections were broken. As long as nobody requests evaluation of the blocked node directly it wont evaluate after that. Note that a blocked node will still respond to getAttrrequests but a getAttron a downstream node will not reevaluate the blocked node. Setting the root transform of a hierarchy to Blockingwont automatically influence child transforms in the hierarchy. To do this, youd need to explicitly set all child nodes to the Blockingstate. For example, to set all child transforms to Blocking, you could use the following script. import maya.cmds as cmds def blockTree(root): nodesToBlock = [] for node in {child:1 for child in cmds.listRelatives( root, path=True, allDescendents=True )}.keys(): nodesToBlock += cmds.listConnections(node, source=True, destination=True ) for node in {source:1 for source in nodesToBlock}.keys(): cmds.setAttr( ‘%s.nodeState’ % node, 2 ) Applying this script would continue to draw objects but things would not be animated. Default:kdnNormal
object / o		bool
	Create the result, or just the dependency node.
pivot / p		float, float, float
	Revolve pivot point
pivotX / px		float
	X of the pivot Default:0
pivotY / py		float
	Y of the pivot Default:0
pivotZ / pz		float
	Z of the pivot Default:0
polygon / po		int
	The value of this argument controls the type of the object created by this operation 0: nurbs surface1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)3: Bezier surface4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
radius / r		float
	The pivot point will be this distance away from the bounding box of the curve, if computedPivot is set to true. The value of the pivot attribute is ignored. Default:1
radiusAnchor / ra		float
	The position on the curve for the anchor point so that we can compute the pivot using the radius value. If in 0 - 1 range, its on the curve, normalized parameter range. If 0 or 1, its computed based on the bounding box. Default:-1
range / rn		bool
	Force a curve range on complete input curve.
rebuild / rb		bool
	Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.
sections / s		int
	Number of sections of the resulting surface (if tolerance is not used). Default:8
startSweep / ssw		float
	The value for the start sweep angle, in the current units. This must be no more than the maximum, 360 degrees, or 2 Pi radians. Default:0
tolerance / tol		float
	Tolerance to build to (if useTolerance attribute is set) Default:0.01
useLocalPivot / ulp		bool
	If true, then the pivot of the profile curve is used as the start point of the axis of revolution. Flag can have multiple arguments, passed either as a tuple or a list.
useTolerance / ut		bool
	Use the tolerance, or the number of sections to control the sections. Default:false Common flags

Derived from mel command maya.cmds.revolve

Example:

import pymel.core as pm

# To revolve a curve about the X axis at the origin. The profile curve is
# revolved by 360 degrees by default.
pm.revolve( 'curve1', ax=(1, 0, 0), p=(0, 0, 0) )

# To revolve a curve about the Y axis at 1,0,1:
pm.revolve( 'curve1', ax=(0, 1, 0), p=(1, 0, 1) )
