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 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 curve for curvature continuity. Default:0.0 curvatureScale2 / cs2 float Curvature scale applied to curvature of second curve for curvature continuity. Default:0.0 frozen / fzn bool joinParameter / jnp float Parameter on reference curve where modified curve 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 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 Create in place(i.e., replace). Advanced flags reverse1 / rv1 bool 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 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 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 curve, 2 - do tangent continuity on second curve Default:1 tangentScale1 / ts1 float Tangent scale applied to tangent of first curve for tangent continuity. Default:1.0 tangentScale2 / ts2 float 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 )
