extrude is undoable, queryable, and editable.
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.

Properties |
extrudeType(et)
|
int
|
  
|
|
The extrude type (distance-0, flat-1, or tube-2)
Default: 2
|
|
fixedPath(fpt)
|
boolean
|
|
|
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
|
|
useComponentPivot(ucp)
|
int
|
|
|
Use closest endpoint of the path - 0, component pivot - 1 or the center of the bounding box of the profile - 2
Default: 0
|
|
useProfileNormal(upn)
|
boolean
|
|
|
If true, use the profile curve normal for the direction in which to extrude.
Use only for distance or tube extrudeType.
Default: false
|
|
direction(d)
|
[linear, linear, linear]
|
|
|
The direction in which to extrude.
Use only for distance extrudeType and useProfileNormal off
|
|
directionX(dx)
|
linear
|
|
|
X of the direction
Default: 0
|
|
directionY(dy)
|
linear
|
|
|
Y of the direction
Default: 1
|
|
directionZ(dz)
|
linear
|
|
|
Z of the direction
Default: 0
|
|
length(l)
|
linear
|
|
|
The distance to extrude.
Use only for distance extrudeType
Default: 1
|
|
pivot(p)
|
[linear, linear, linear]
|
|
|
The pivot point used for tube extrudeType
|
|
rotation(ro)
|
angle
|
|
|
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
|
|
reverseSurfaceIfPathReversed(rsp)
|
boolean
|
|
|
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
|
|
degreeAlongLength(dl)
|
int
|
|
|
Surface degree along the distance when a distance extrude is performed
Default: 1
|
|
subCurveSubSurface(scs)
|
boolean
|
|
|
If true, curve range on the path will get applied to the resulting surface instead of cut before the extrude.
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.
Note: For advanced users only.
|
|
| Common flags |
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.

|
constructionHistory(ch)
|
boolean
|
|
|
Turn the construction history on or off
|
|
object(o)
|
boolean
|
|

|
polygon(po)
|
int
|
|
|
The value of this argument controls the type of the object
created by this operation
- 0: nurbs surface
- 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)
- 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)
- 3: Bezier surface
- 4: subdivision surface solid (use nurbsToSubdivPref to set the
parameters for the conversion)
|
|
range(rn)
|
boolean

|
|
Force a curve range on complete input curve
|
|
rebuild(rb)
|
boolean
|
|
|
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.
