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.

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 curvesDefault:1

replaceOriginal (rpo) bool ../../../_images/create.gif
 
Create “in place” (i.e., replace)Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
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 curveDefault: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

Derived from mel command maya.cmds.alignCurve

Example:

import pymel.core as pm

import maya.cmds as cmds

# 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 )
