revolve is undoable, queryable, and editable.

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.

Return value

string[]Object name and node name

In query mode, return type is based on queried flag.

Long name (short name) Argument types Properties
-autoCorrectNormal(-acn) boolean createqueryedit
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) linear linear linear createqueryedit
Revolve axis
-axisChoice(-aco) int createqueryedit
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) linear createqueryedit
X of the axis
Default: 1
-axisY(-axy) linear createqueryedit
Y of the axis
Default: 0
-axisZ(-axz) linear createqueryedit
Z of the axis
Default: 0
-bridge(-br) boolean createqueryedit
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) boolean createqueryedit
Toggle caching for all attributes so that no recomputation is needed
-computePivotAndAxis(-cpa) int createqueryedit
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
-degree(-d) int createqueryedit
The degree of the resulting surface.
Default: 3
-endSweep(-esw) angle createqueryedit
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
-nodeState(-nds) int createqueryedit

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-Blocking will reset back to Blocking.

The Normal and Blocking cases apply to all nodes, while HasNoEffect is node specific; many nodes do not support this option. Plug-ins store state in the MPxNode::state attribute. Anyone can set it or check this attribute. Additional details about each of these 3 states follow.

State Description
Normal The normal node state. This is the default.
HasNoEffect

The HasNoEffect option (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.

It’s typical to implement support for the HasNoEffect state in the node’s 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.

Blocking

This is implemented in the depend node base class and applies to all nodes. Blocking is 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 Blocking the 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 won’t evaluate after that. Note that a blocked node will still respond to getAttr requests but a getAttr on a downstream node will not reevaluate the blocked node.

Setting the root transform of a hierarchy to Blocking won’t automatically influence child transforms in the hierarchy. To do this, you’d need to explicitly set all child nodes to the Blocking state.

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
-pivot(-p) linear linear linear createqueryedit
Revolve pivot point
-pivotX(-px) linear createqueryedit
X of the pivot
Default: 0
-pivotY(-py) linear createqueryedit
Y of the pivot
Default: 0
-pivotZ(-pz) linear createqueryedit
Z of the pivot
Default: 0
-radius(-r) linear createqueryedit
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 createqueryedit
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
-sections(-s) int createqueryedit
Number of sections of the resulting surface (if tolerance is not used).
Default: 8
-startSweep(-ssw) angle createqueryedit
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) linear createqueryedit
Tolerance to build to (if useTolerance attribute is set)
Default: 0.01
-useTolerance(-ut) boolean createqueryedit
Use the tolerance, or the number of sections to control the sections.
Default: false
Common flags
-constructionHistory(-ch) boolean create
Turn the construction history on or off.
-name(-n) string create
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.
-object(-o) boolean create
Create the result, or just the dependency node.
-polygon(-po) int create
The value of this argument controls the type of the object created by this operation
  • 0: nurbs surface
  • 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)
  • 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)
  • 3: Bezier surface
  • 4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
-range(-rn) boolean create
Force a curve range on complete input curve.
-rebuild(-rb) boolean create
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.
-useLocalPivot(-ulp) boolean createqueryedit
If true, then the pivot of the profile curve is used as the start point of the axis of revolution.
