Synopsis

alignCurve [-caching boolean] [-constructionHistory boolean] [-curvatureContinuity boolean] [-curvatureScale1 float] [-curvatureScale2 float] [-joinParameter float] [-name string] [-nodeState int] [-object boolean] [-positionalContinuity boolean] [-positionalContinuityType int] [-replaceOriginal boolean] [-reverse1 boolean] [-reverse2 boolean] [-tangentContinuity boolean] [-tangentContinuityType int] [-tangentScale1 float] [-tangentScale2 float] [curve] [curve]

alignCurve is undoable, queryable, and editable.

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.

Return value

string[]Object name and node name

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

Long name (short name) Argument types Properties
-curvatureContinuity(-cc) boolean createqueryedit
Curvature continuity is on if true and off otherwise.
Default: false
-curvatureScale1(-cs1) float createqueryedit
Curvature scale applied to curvature of first curve for curvature continuity.
Default: 0.0
-curvatureScale2(-cs2) float createqueryedit
Curvature scale applied to curvature of second curve for curvature continuity.
Default: 0.0
-joinParameter(-jnp) float createqueryedit
Parameter on reference curve where modified curve is to be aligned to.
Default: 123456.0
-positionalContinuity(-pc) boolean createqueryedit
Positional continuity is on if true and off otherwise.
Default: true
-positionalContinuityType(-pct) int createqueryedit
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
-reverse1(-rv1) boolean createqueryedit
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) boolean createqueryedit
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) boolean createqueryedit
Tangent continuity is on if true and off otherwise.
Default: true
-tangentContinuityType(-tct) int createqueryedit
Tangent continuity type legal values: 1 - do tangent continuity on first curve, 2 - do tangent continuity on second curve
Default: 1
-tangentScale1(-ts1) float createqueryedit
Tangent scale applied to tangent of first curve for tangent continuity.
Default: 1.0
-tangentScale2(-ts2) float createqueryedit
Tangent scale applied to tangent of second curve for tangent continuity.
Default: 1.0
Common flags
-constructionHistory(-ch) boolean create
Turn the construction history on or off.
-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.
-object(-o) boolean create
Create the result, or just the dependency node.
-replaceOriginal(-rpo) boolean create
Create "in place" (i.e., replace).
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.
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 be used more than once in a command.

MEL examples

// Do modify positional continuity on both curves with no history:
 alignCurve -ch off -pc on -pct 6;

// Do positional and tangent continuity, with the second curve
// tangent modified (by default move position continuity is done
// on the first curve):
 alignCurve -tc on -tct 2;
