Extrude Curve
Straight
The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.
Notes
| ● | If the curve is not planar, then it will be extruded in the z-direction of the active viewport's construction plane. If the curve is planar, it will be extruded in the normal direction of the plane of the curve. |
| ● | Unlike Lofts and Sweeps, the initial orientation of the profile curve or surface is maintained through the extrusion. |
| ● | If the input is a non-planar polycurve or a planar polycurve where the extrusion direction is not normal to the curve plane, the result will be a polysurface rather than an extrusion object. |
Command-line options
SetBasePoint
Specify a location that serves as the first point when picking two points that set the extrusion distance.
Direction
Two points establish the direction angle.
BothSides
The BothSides option draws the object on both sides of the start point, creating the object twice as long as you indicate.
The BothSides option demonstrated with the Line command.
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
Extrudes the object to a boundary surface.
DeleteInput
Yes
Deletes the original geometry.
No
Retains the original geometry.
SplitAtTangents=Yes/No
The Yes option creates a single surface.
The No option creates a polysurface when the input curves are joined tangent curves. Faces in the resulting polysurface correspond to the tangent sub-curves in the input curves.
Original polycurve (left), SplitAtTangents=No (center), SplitAtTangents=Yes (right).
Notes
| ● | When this option is used, the output will be a polysurface. |
| ● | When UseExtrusions is on, this setting has no effect. |
