Solid Extrude Planar Curve > Straight Surface Extrude Curve > Straight SubD Extrude Curve > Straight |
The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.
Steps
- Select a curve.
- Specify a distance.
- A planar curve extrudes vertically to the curve plane by default. If the curve is not planar, the default extrusion direction is the z direction of the active CPlane.
-
The extrusion preview direction in the viewport defines the positive direction for distance input.
- An extrusion object will be created only if the input curve is planar and the extrusion direction is vertical to the curve plane. Otherwise, a polysurface will be created. If you would like to always create a polysurface, you can disable the Uses Extrusions when possible option.
Command-line options
Output
Surface
Create an extrusion or a surface object.
SubD
Create a SubD object.
- A SubD friendly curve as the input creates a better SubD object.
- Some options may not be available when Output=SubD.
Direction
Pick two points to define the extruding direction.
BothSides
Extrude towards the both sides of the input curve.
Solid
If the profile curve is closed and planar, both ends of the extruded object are filled with planar surfaces and joined to make a closed polysurface.
ToBoundary
Extrude the object to a boundary surface.
DeleteInput
Deletes (Yes) or keeps (No) the input object.
SplitAtTangents
Yes
Tangent points on the input curve extrude as joined edges.
No
Tangent points on the input curve extrude as surface kinks.
- The SplitAtTangents option is not available when the UseExtrusions command is set to Extrusion which is by default.
SetBasePoint
Specify a location that serves as the first point when picking two points that set the extrusion distance.
SubCrv
Type subcrv to select part of a curve as input.
