Synopsis

rebuildCurve [-caching boolean] [-constructionHistory boolean] [-degree int] [-endKnots int] [-fitRebuild boolean] [-keepControlPoints boolean] [-keepEndPoints boolean] [-keepRange int] [-keepTangents boolean] [-name string] [-nodeState int] [-object boolean] [-range boolean] [-rebuildType int] [-replaceOriginal boolean] [-smartSurfaceCurveRebuild boolean] [-spans int] [-tolerance linear] curve [curve]

rebuildCurve is undoable, queryable, and editable.

This command rebuilds a curve by modifying its parameterization. In some cases the shape may also change. The rebuildType (-rt) determines how the curve is to be rebuilt. The optional second curve can be used to specify a reference parameterization.

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
-fitRebuild(-fr) boolean createqueryedit
If true use the least squares fit rebuild. Otherwise use the convert method.
Default: true
-rebuildType(-rt) int createqueryedit
How to rebuild the input curve. 0 - uniform, 1 - reduce spans, 2 - match knots, 3 - remove multiple knots, 4 - curvature 5 - rebuild ends 6 - clean
Default: 0
-spans(-s) int createqueryedit
The number of spans in resulting curve Used only if rebuildType is uniform.
Default: 4
-degree(-d) int createqueryedit
The degree of the resulting curve 1 - linear, 2 - quadratic, 3 - cubic, 5 - quintic, 7 - heptic
Default: 3
-tolerance(-tol) linear createqueryedit
The tolerance with which to rebuild.
Default: 0.01
-endKnots(-end) int createqueryedit
End conditions for the curve 0 - uniform end knots, 1 - multiple end knots,
Default: 0
-keepRange(-kr) int createqueryedit
Determine the parameterization for the resulting curve. 0 - reparameterize the resulting curve from 0 to 1, 1 - keep the original curve parameterization, 2 - reparameterize the result from 0 to number of spans
Default: 1
-keepEndPoints(-kep) boolean createqueryedit
If true, keep the endpoints the same.
Default: true
-keepTangents(-kt) boolean createqueryedit
If true, keep the end tangents the same.
Default: true
-keepControlPoints(-kcp) boolean createqueryedit
If true, the CVs will remain the same. This forces uniform parameterization unless rebuildType is matchKnots.
Default: false
-smartSurfaceCurveRebuild( -scr) boolean createqueryedit
If true, curve on surface is rebuild in 3D and 2D info is kept
Default: false
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.
Common flags
-name(-n) string create
Name the resulting object
-constructionHistory(-ch) boolean create
Turn the construction history on or off
-object(-o) boolean create
Create the result, or just the dependency node
-replaceOriginal(-rpo) boolean create
Create "in place" (i.e., replace)
-range(-rn) boolean create
Force a curve range on complete input curve

Flag can appear in Query mode of command Flag can be used more than once in a command.
