Synopsis

insertKnotSurface [-addKnots boolean] [-caching boolean] [-constructionHistory boolean] [-direction int] [-insertBetween boolean] [-name string] [-nodeState int] [-numberOfKnots int] [-object boolean] [-parameter float] [-replaceOriginal boolean] surface

insertKnotSurface is undoable, queryable, and editable.

You must specify one, none or all number of knots with the "-nk" flag. eg. if you specify none, then the default (one) knot will be added at each specified parameter value. If you specify one "-nk" value then that number of knots will be added at each parameter value. Otherwise, you must specify the same number of "-nk" flags as "-p" flags, defining the number of knots to be added at each specified parameter value.

You can insert up to "degree" knots at a parameter value that isn't already an isoparm. eg. for a degree 3 surface, you can insert up to 3 knots.

Use this operation if you need more CVs in a local area of the surface. Use this operation if you want to create a corner in the surface.

Note: A single insertKnotSurface command cannot insert in both directions at once; you must use two separate commands to do this.

Return value

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

Flags

Long name (short name)	Argument types	Properties
-addKnots(-add)	boolean
Whether to add knots or complement. Complement means knots will be added to reach the specified number of knots. Default: true
-direction(-d)	int
Direction in which to insert knot: 0 - V direction, 1 - U direction Default: 1
-insertBetween(-ib)	boolean
If set to true, and there is more than one parameter value specified, the knots will get inserted at equally spaced intervals between the given parameter values, rather than at the parameter values themselves. Default: false
-numberOfKnots(-nk)	int
How many knots to insert Default: 1
-parameter(-p)	float
Parameter value(s) where knots are added Default: 0.0
Common flags
-constructionHistory(-ch)	boolean
Turn the construction history on or off.
-name(-n)	string
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 the result, or just the dependency node.
-replaceOriginal(-rpo)	boolean
Create "in place" (i.e., replace).
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. 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

insertKnotSurface -ch on -p 0.3 -d 0 surface1;
insertKnotSurface -ch on surface1.v[0.3];
// Inserts one knot (which is the default) into surface1 at
// parameter value v = 0.3.  When an isoparm is specified, the direction
// and parameter value is implied and the "-p" and "-d" flags can be omitted.

insertKnotSurface -ch on -p 0.3 -nk 2 -d 0 surface1;
// Inserts two knots into surface1 at parameter value v = 0.3.

insertKnotSurface -ch on -p 0.3 -p 0.5 -p 0.8 -nk 2 -d 0 surface1;
// Inserts two knots at each parameter value v = 0.3, 0.5 and 0.8.

insertKnotSurface -ch on -p 0.5 -add off -nk 3 -d 1 surface1;
// Inserts enough knots into surface1 at parameter value u = 0.5 to
// achieve a knot multiplicity of 3.
