extrude

Go to: Related nodes. Attributes.

Create a surface by extruding a profile curve. There are three ways to perform the extrusion (extrueType):

distance - The profile is extruded along a vector (direction) by a given distance (length).

flat - The profile is extruded along a path curve. The relationship between the profile and path remains the same as the profile travels along the path.

tube - The profile is extruded along a path curve. The profile is rotated as it travels along a path.

The location of the resulting surface can be controlled by fixedPath. The shape of the resulting surface can be controlled by useProfileNormal, useComponentPivot and the placement of each object's pivot point.
The resulting surface can be scaled and rotated (for each extrude type) to produce spirals and twists in the surface. The pivot point is only used for flat and distance extrude type if there is a rotation/scale.

Long name (short name)	Type	Default	Flags
profile (pr)	nurbsCurve	NULL
The curve to extrude (profile).
path (pt)	nurbsCurve	NULL
The path curve. Used only if extrudeType is flat or tube
extrudeType (et)	enum	2
The extrude type (distance-0, flat-1, or tube-2)
fixedPath (fpt)	bool	false
If true, the resulting surface will be placed at the path curve. Otherwise, the resulting surface will be placed at the profile curve.
useComponentPivot (ucp)	enum	0
Use closest endpoint of the path - 0, component pivot - 1 or the center of the bounding box of the profile - 2
useProfileNormal (upn)	bool	false
If true, use the profile curve normal for the direction in which to extrude. Use only for distance or tube extrudeType.
direction (d)	double3
The direction in which to extrude. Use only for distance extrudeType and useProfileNormal off
directionX (dx) distance (double) 0cm X of the direction
directionY (dy) distance (double) 1cm Y of the direction
directionZ (dz) distance (double) 0cm Z of the direction
length (l)	distance (double)	1cm
The distance to extrude. Use only for distance extrudeType
pivot (p)	double3
The pivot point used for tube extrudeType
pivotX (px) distance (double) 0cm X of the pivot
pivotY (py) distance (double) 0cm Y of the pivot
pivotZ (pz) distance (double) 0cm Z of the pivot
rotation (ro)	angle (double)	0.0deg
Amount to rotate the profile curve as it sweeps along the path curve.
scale (sc)	double	1.0
Amount to scale the profile curve as it sweeps along the path curve.
reverseSurfaceIfPathReversed (rsp)	bool	false
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.
degreeAlongLength (dl)	short	1
Surface degree along the distance when a distance extrude is performed
subCurveSubSurface (scs)	bool	false
If true, curve range on the path will get applied to the resulting surface instead of cut before the extrude.
outputSurface (os)	nurbsSurface	NULL
The extruded surface.
