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.

Properties |
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 |
|
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 |
|
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 |
|
tangentContinuityType(tct) |
int |
|
|
Tangent continuity type legal values: 1 - do tangent continuity
on first curve, 2 - do tangent continuity on second curve
Default: 1 |
|
joinParameter(jnp) |
float |
|
|
Parameter on reference curve where modified curve is to be
aligned to.
Default: 123456.0 |
|
reverse1(rv1) |
boolean |
|
|
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 |
|
|
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 |
|
positionalContinuity(pc) |
boolean |
|
|
Positional continuity is on if true and off otherwise.
Default: true |
|
tangentContinuity(tc) |
boolean |
|
|
Tangent continuity is on if true and off otherwise.
Default: true |
|
curvatureContinuity(cc) |
boolean |
|
|
Curvature continuity is on if true and off otherwise.
Default: false |
|
| Advanced flags |
caching(cch) |
boolean |
|
|
Modifies the node caching mode. See the node documentation for
more information.
Note: For advanced users only. |
|
nodeState(nds) |
int |
|
|
Modifies the node state. See the node documentation for more
information.

boolean |
|
|

|
replaceOriginal(rpo) |
boolean |
|
|
Create "in place" (i.e., replace) |
|
| Flag can appear in Create mode of
command |
Flag can appear in Edit mode of command |

 Flag can have multiple arguments, passed
either as a tuple or a list. |
