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.

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
degreeAlongLength(dl) int createqueryedit
Surface degree along the distance when a distance extrude is performed
Default: 1
direction(d) [linear, linear, linear] createqueryedit
The direction in which to extrude. Use only for distance extrudeType and useProfileNormal off
directionX(dx) linear createqueryedit
X of the direction
Default: 0
directionY(dy) linear createqueryedit
Y of the direction
Default: 1
directionZ(dz) linear createqueryedit
Z of the direction
Default: 0
extrudeType(et) int createqueryedit
The extrude type (distance-0, flat-1, or tube-2)
Default: 2
fixedPath(fpt) boolean createqueryedit
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) linear createqueryedit
The distance to extrude. Use only for distance extrudeType
Default: 1
pivot(p) [linear, linear, linear] createqueryedit
The pivot point used for tube extrudeType
reverseSurfaceIfPathReversed(rsp) boolean createqueryedit
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) angle createqueryedit
Amount to rotate the profile curve as it sweeps along the path curve.
Default: 0.0
scale(sc) float createqueryedit
Amount to scale the profile curve as it sweeps along the path curve.
Default: 1.0
subCurveSubSurface(scs) boolean createqueryedit
If true, curve range on the path will get applied to the resulting surface instead of cut before the extrude.
Default: false
useComponentPivot(ucp) int createqueryedit
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 createqueryedit
If true, use the profile curve normal for the direction in which to extrude. Use only for distance or tube extrudeType.
Default: false
Common flags
constructionHistory(ch) boolean create
Turn the construction history on or off.
name(n) string create
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
Create the result, or just the dependency node.
polygon(po) int create
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 create
Force a curve range on complete input curve.
rebuild(rb) boolean create
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.
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.
