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

Argument types |
Properties |
|
-autoCorrectNormal(-acn)
|
boolean
|
|
|
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
|
|
|
-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)
|
linear
|
|
|
-axisY(-axy)
|
linear
|
|
|
-axisZ(-axz)
|
linear
|
|
|
-bridge(-br)
|
boolean
|
|
|
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
|
|
|
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
|
|
-degree(-d)
|
int
|
|
|
The degree of the resulting surface.
Default: 3
|
|
-endSweep(-esw)
|
angle
|
|
|
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
|
|
|
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.

-pivot(-p)

-pivotX(-px)
|
linear
|
|
|
X of the pivot

-radius(-r)

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.

-name(-n)

will be created.

|
Create the result, or just the dependency node.
