Synopsis

attachSurface( [surface] [surface] , [blendBias=float], [blendKnotInsertion=boolean], [caching=boolean], [constructionHistory=boolean], [directionU=boolean], [keepMultipleKnots=boolean], [method=int], [name=string], [nodeState=int], [object=boolean], [parameter=float], [replaceOriginal=boolean], [reverse1=boolean], [reverse2=boolean], [swap1=boolean], [swap2=boolean], [twist=boolean])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

attachSurface is undoable, queryable, and editable.

This attach command is used to attach surfaces. Once the surfaces are attached, there will be multiple knots at the joined point(s). These can be kept or removed if the user wishes.

The end of the first surface is attached to the start of the second surface in the specified direction.

Note: if the command is done with Keep Original off there will be an extra surface in the model (the second surface). The command does not delete it. The first surface is replaced by the attached surface.

Return value

string[]Object name and node name

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

Flags

blendBias, blendKnotInsertion, caching, constructionHistory, directionU, keepMultipleKnots, method, name, nodeState, object, parameter, replaceOriginal, reverse1, reverse2, swap1, swap2, twist
Long name (short name) Argument types Properties
method(m) int createqueryedit
Attach method (connect-0, blend-1)
Default: 0
directionU(du) boolean createqueryedit
If true attach in U direction of surface and V direction otherwise.
Default: true
reverse1(rv1) boolean createqueryedit
If true, reverse the direction (specified by directionU) of the first input surface before doing attach. Otherwise, do nothing to the first input surface before attaching. NOTE: setting this attribute to random values will cause unpredictable results and is not supported.
Default: false
reverse2(rv2) boolean createqueryedit
If true, reverse the direction (specified by directionU) of the second input surface before doing attach. Otherwise, do nothing to the second input surface before attaching. NOTE: setting this attribute to random values will cause unpredictable results and is not supported.
Default: false
swap1(sw1) boolean createqueryedit
If true, swap the UV directions of the first input surface before doing attach. Otherwise, do nothing to the first input surface before attaching. NOTE: setting this attribute to random values will cause unpredictable results and is not supported.
Default: false
swap2(sw2) boolean createqueryedit
If true, swap the UV directions of the second input surface before doing attach. Otherwise, do nothing to the second input surface before attaching. NOTE: setting this attribute to random values will cause unpredictable results and is not supported.
Default: false
twist(tw) boolean createqueryedit
If true, reverse the second surface in the opposite direction (specified by directionU) before doing attach. This will avoid twists in the attached surfaces. Otherwise, do nothing to the second input surface before attaching. NOTE: setting this attribute to random values will cause unpredictable results and is not supported.
Default: false
blendBias(bb) float createqueryedit
Skew the result toward the first or the second curve depending on the blend factory being smaller or larger than 0.5.
Default: 0.5
blendKnotInsertion(bki) boolean createqueryedit
If set to true, insert a knot in one of the original curves (relative position given by the parameter attribute below) in order to produce a slightly different effect.
Default: false
parameter(p) float createqueryedit
The parameter value for the positioning of the newly inserted knot.
Default: 0.1
keepMultipleKnots(kmk) boolean createqueryedit
If true, keep multiple knots at the join parameter. Otherwise remove them.
Default: true
Advanced flags
caching(cch) boolean createqueryedit
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
nodeState(nds) int createqueryedit
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.
Common flags
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.
constructionHistory(ch) boolean create
Turn the construction history on or off
object(o) boolean create
Create the result, or just the dependency node
replaceOriginal(rpo) boolean create
Create "in place" (i.e., replace)
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.

Python examples

import maya.cmds as cmds

# Attach the nurbs planes (in the default U direction) and remove the
# multiple knots:
cmds.attachSurface( 'nurbsPlane1', 'nurbsPlane2', kmk=False )

# Attach the two active surfaces along the v direction (keeps multiple
# knots by default):
cmds.attachSurface( du=False )
