pymel.core.modeling.alignSurface¶

alignSurface(*args, **kwargs)¶

The surface align command is used to align surfaces in maya. The main alignment options are positional, tangent and curvature continuity. Curvature continuity implies tangent continuity. NOTE: this tool is based on Studio’s align tool. Positional continuity means the surfaces (move) or the ends of the surfaces (modify) are changed. Tangent continuity means one of the surfaces is modified to be tangent at the points where they meet. Curvature continuity means one of the surfaces is modified to be curvature continuous as well as tangent. The default behaviour, when no surfaces or flags are passed, is to only do positional and tangent continuity on the active list with the end of the first surface and the start of the other surface used for alignment.

Flags:

Long Name / Short Name		Argument Types	Properties
attach / at		bool
caching / cch		bool
	Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
constructionHistory / ch		bool
	Turn the construction history on or off.
curvatureContinuity / cc		bool
	Curvature continuity is on if true and off otherwise. Default:false
curvatureScale1 / cs1		float
	Curvature scale applied to curvature of first surface for curvature continuity. Default:0.0
curvatureScale2 / cs2		float
	Curvature scale applied to curvature of second surface for curvature continuity. Default:0.0
directionU / du		bool
	If true use U direction of surface and V direction otherwise. Default:true
frozen / fzn		bool
joinParameter / jnp		float
	Parameter on reference surface where modified surface is to be aligned to. Default:123456.0
keepMultipleKnots / kmk		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
	Modifies the node state. See the node documentation for more information. Note:For advanced users only. Flag can have multiple arguments, passed either as a tuple or a list.
object / o		bool
	Create the result, or just the dependency node.
positionalContinuity / pc		bool
	Positional continuity is on if true and off otherwise. Default:true
positionalContinuityType / pct		int
	Positional continuity type legal values: 1 - move first surface, 2 - move second surface, 3 - move both surfaces, 4 - modify first surface, 5 - modify second surface, 6 - modify both surfaces Default:1
replaceOriginal / rpo		bool
	Create in place(i.e., replace). Advanced flags
reverse1 / rv1		bool
	If true, reverse the direction (specified by directionU) of the first input surface before doing align. Otherwise, do nothing to the first input surface before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
reverse2 / rv2		bool
	If true, reverse the direction (specified by directionU) of the second input surface before doing align. Otherwise, do nothing to the second input surface before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
swap1 / sw1		bool
	If true, swap the UV directions of the first input surface before doing align. Otherwise, do nothing to the first input surface before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
swap2 / sw2		bool
	If true, swap the UV directions of the second input surface before doing align. Otherwise, do nothing to the second input surface before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
tangentContinuity / tc		bool
	Tangent continuity is on if true and off otherwise. Default:true
tangentContinuityType / tct		int
	Tangent continuity type legal values: 1 - do tangent continuity on first surface, 2 - do tangent continuity on second surface Default:1
tangentScale1 / ts1		float
	Tangent scale applied to tangent of first surface for tangent continuity. Default:1.0
tangentScale2 / ts2		float
	Tangent scale applied to tangent of second surface for tangent continuity. Default:1.0
twist / tw		bool
	If true, reverse the second surface in the opposite direction (specified by directionU) before doing align. This will avoid twists in the aligned surfaces. Otherwise, do nothing to the second input surface before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false Common flags

Derived from mel command maya.cmds.alignSurface

Example:

import pymel.core as pm

# Do modify positional continuity on both active surfaces with no history:
pm.alignSurface( ch=False, pc=True, pct=6 )

# Do positional and tangent continuity, with the second surface
# tangent modified (by default move position continuity is done
# on the first surface):
pm.alignSurface( tc=True, tct=2 )
