pymel.core.modeling.alignCurve

alignCurve(*args, **kwargs)

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

Flags:

Long Name / Short Name Argument Types Properties
attach / at bool  
   
caching / cch bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
constructionHistory / ch bool ../../../_images/create.gif
  Turn the construction history on or off.
curvatureContinuity / cc bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Curvature continuity is on if true and off otherwise. Default:false
curvatureScale1 / cs1 float ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Curvature scale applied to curvature of first curve for curvature continuity. Default:0.0
curvatureScale2 / cs2 float ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Curvature scale applied to curvature of second curve for curvature continuity. Default:0.0
frozen / fzn bool  
   
joinParameter / jnp float ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Parameter on reference curve where modified curve is to be aligned to. Default:123456.0
keepMultipleKnots / kmk bool  
   
name / n unicode ../../../_images/create.gif
  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 ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  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 ../../../_images/create.gif
  Create the result, or just the dependency node.
positionalContinuity / pc bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Positional continuity is on if true and off otherwise. Default:true
positionalContinuityType / pct int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Positional continuity type legal values: 1 - move first curve, 2 - move second curve, 3 - move both curves, 4 - modify first curve, 5 - modify second curve, 6 - modify both curves Default:1
replaceOriginal / rpo bool ../../../_images/create.gif
  Create in place(i.e., replace). Advanced flags
reverse1 / rv1 bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  If true, reverse the first input curve before doing align. Otherwise, do nothing to the first input curve before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
reverse2 / rv2 bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  If true, reverse the second input curve before doing align. Otherwise, do nothing to the second input curve before aligning. NOTE: setting this attribute to random values will cause unpredictable results and is not supported. Default:false
tangentContinuity / tc bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Tangent continuity is on if true and off otherwise. Default:true
tangentContinuityType / tct int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Tangent continuity type legal values: 1 - do tangent continuity on first curve, 2 - do tangent continuity on second curve Default:1
tangentScale1 / ts1 float ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Tangent scale applied to tangent of first curve for tangent continuity. Default:1.0
tangentScale2 / ts2 float ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
  Tangent scale applied to tangent of second curve for tangent continuity. Default:1.0 Common flags

Derived from mel command maya.cmds.alignCurve

Example:

import pymel.core as pm

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

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