The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.
|●||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.|
Specify a location that serves as the first point when picking two points that set the extrusion distance.
Two points establish the direction angle.
|1.||Pick a base point.|
|2.||Pick a second point that establishes the direction angle.|
The BothSides option draws the object on both sides of the start point, creating the object twice as long as you indicate.
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.
Extrudes the object to a boundary surface.
Deletes the original geometry.
Retains the original geometry.
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.
|●||When this option is used, the output will be a polysurface.|
|●||When UseExtrusions is on, this setting has no effect.|
