filterExpand([expand=boolean], [fullPath=boolean], [selectionMask=int], [symActive=boolean], [symNegative=boolean], [symPositive=boolean], [symSeam=boolean])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
filterExpand is undoable, NOT queryable, and NOT editable.
Based on selected components (or components specified on the command line),
the command filters and/or expands the list given
the options.
Returns a string array containing all matching selection items.
Selection masks are as follows:
| Object Type | Mask |

| Polygon Edges | 32 |
| Polygon Face | 34 |
| Polygon UVs | 35 |
| Subdivision Mesh Points | 36 |
| Subdivision Mesh Edges | 37 |
| Subdivision Mesh Faces | 38 |
| Curve Parameter Points | 39 |
| Curve Knot | 40 |
| Surface Parameter Points | 41 |
| Surface Knot | 42 |
| Surface Range | 43 |
| Trim Surface Edge | 44 |
| Surface Isoparms | 45 |
| Lattice Points | 46 |
| Particles | 47 |
| Scale Pivots | 49 |
| Rotate Pivots | 50 |

Properties |
|
expand(ex)
|
boolean
|
|
|
Each item is a single entity if this is true. Default is true.
|
|
fullPath(fp)
|
boolean
|
|
|
If this is true and the selection item is a DAG object, return its
full selection path, instead of the name of the object only when
this value is false. Default is false.
|
|
selectionMask(sm)
|
int
|
|
|
Specify the selection mask
|
|
symActive(sma)
|
boolean
|
|
|
If symmetry is enabled only return the components on the active symmetry
side of the object. This flag has no effect if symmetry is not active.
|
|
symNegative(smn)
|
boolean
|
|
|
If symmetry is enabled only return the components on the negative
side of the object relative to the current symmetry plane. This flag has
no effect if symmetry is not active.
|
|
symPositive(smp)
|
boolean
|
|
|
If symmetry is enabled only return the components on the positive
side of the object relative to the current symmetry plane. This flag has
no effect if symmetry is not active.
|
|
symSeam(sms)
|
boolean
|
|
|
If symmetry is enabled only return the components that lie equally on both sides
of the object relative to the current symmetry plane. This flag has
no effect if symmetry is not active.
|

Flag can appear in Create mode of command
|
Flag can appear in Edit mode of command
|
Flag can appear in Query mode of command
|
Flag can have multiple arguments, passed either as a tuple or a list.

import maya.cmds as cmds
# Returns any selected isoparms (mask 45) as individual items
# (because of "ex=True").
cmds.filterExpand( ex=True, sm=45 )
# Returns any selected CVs (mask 28) as compact items. For example,
# if curve.cv[0:3] is selected, then "curve.cv[0:3]" is returned.
# If "ex=True", then four items are returned, one for each CV.
cmds.filterExpand( ex=False, sm=28 )
# Returns any selected CVs (mask 28) and edit points (mask 30).
cmds.filterExpand( sm=(28,30) )
# Returns any selected nurbs curves.
cmds.filterExpand( sm=9 )
# Returns any selected nurbs curves-on-surface.
cmds.filterExpand( sm=11 )
# return the poly faces (mask 34) from the specified arguments
cmds.filterExpand(["pCube1.f[1]","pCube1.f[4]","pCube1.vtx[0:3]"], sm=34)
