extrude(*args, **kwargs)

This command computes a surface given a profile curve and possibly a path curve. There are three ways to extrude a profile curve. The most basic method is called a “distance” extrude where direction and length are specified. No path curve is necessary in this case. The second method is called “flat” extrude. This method sweeps the profile curve down the path curve without changing the orientation of the profile curve. Finally, the third method is called “tube” extrude. This method sweeps a profile curve down a path curve while the profile curve rotates so that it maintains a relationship with the path curve.

Flags:

Long name (short name)		Argument Types	Properties
caching (cch)		bool
	Modifies the node caching mode. See the node documentation for more information.Note:For advanced users only.

	Turn the construction history on or off
degreeAlongLength (dl)		int
	Surface degree along the distance when a distance extrude is performedDefault:1
direction (d)		float, float, float
	The direction in which to extrude. Use only for distance extrudeType and useProfileNormal off
directionX (dx)		float
	X of the directionDefault:0
directionY (dy)		float
	Y of the directionDefault:1
directionZ (dz)		float
	Z of the directionDefault:0
extrudeType (et)		int
	The extrude type (distance-0, flat-1, or tube-2)Default:2
fixedPath (fpt)		bool
	If true, the resulting surface will be placed at the path curve. Otherwise, the resulting surface will be placed at the profile curve.Default:false
length (l)		float
	The distance to extrude. Use only for distance extrudeTypeDefault:1
mergeItems (mi)		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.Common flags
object (o)		bool
	Create the result, or just the dependency node
pivot (p)		float, float, float
	The pivot point used for tube extrudeType
polygon (po)		int
	The value of this argument controls the type of the object created by this operation 0: nurbs surface1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)3: Bezier surface4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
range (rn)		bool
	Force a curve range on complete input curve
rebuild (rb)		bool
	Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
reverseSurfaceIfPathReversed (rsp)		bool
	If true, extrude type is tube (2) and path has been internally reversed then computed surface is reversed in the direction corresponding to the path.Default:false
rotation (ro)		float
	Amount to rotate the profile curve as it sweeps along the path curve.Default:0.0
scale (sc)		float
	Amount to scale the profile curve as it sweeps along the path curve.Default:1.0
subCurveSubSurface (scs)		bool
	If true, curve range on the path will get applied to the resulting surface instead of cut before the extrude.Default:falseAdvanced flags
useComponentPivot (ucp)		int
	Use closest endpoint of the path - 0, component pivot - 1 or the center of the bounding box of the profile - 2Default:0
useProfileNormal (upn)		bool
	If true, use the profile curve normal for the direction in which to extrude. Use only for distance or tube extrudeType.Default:false

Derived from mel command maya.cmds.extrude

Example:

import pymel.core as pm

# extrude profile curve "distance" 5 units along x axis
pm.extrude ('profile', et = 0, d= (1, 0, 0), l= 5)

# extrude profile curve along path curve using "flat" method
pm.extrude( 'profile', 'path', et=1 )

# extrude profile curve along path curve using "tube" method
pm.extrude( 'profile', 'path', et=2 )
