EXTRUDE-Command

EXTRUDE (Command)

    EXTRUDE (Command)

    Creates a 3D solid from an object that encloses an area, or a 3D surface from an object
    with open ends.

    Find

    Objects can be extruded orthogonally from the plane of the source object, in a specified
    direction, or along a selected path. You can also specify a taper angle.

    The DELOBJ system variable controls whether the source objects or selected path are
    automatically deleted when the solid or surface is created, or whether you are prompted.

    You can use the following objects and subobjects:

    Objects to Extrude

    Specifies the objects to extrude.

    NOTE:Select face and edge subobjects by pressing Ctrl while you select them.

    Mode

    Controls whether the extruded object is a solid or a surface.

    Surfaces are extruded as either NURBS surfaces or procedural surfaces, depending on
    the SURFACEMODELINGMODE system variable.

    Height of extrusion

    Extrudes selected objects along the positive or negative Z axis. The direction is based on the UCS that was current when the object was created,
    or (for multiple selections) on the original UCS of the most recently created object.

    Direction

    Specifies the length and direction of the extrusion with two specified points. (The
    direction cannot be parallel to the plane of the sweep curve created by the extrusion.)

    Path

    Specifies the extrusion path based on a selected object. The path is moved to the
    centroid of the profile. Then the profile of the selected object is extruded along
    the chosen path to create solids or surfaces.

    NOTE:Select face and edge subobjects by pressing Ctrl while you select them.

    The path should not lie on the same plane as the object, nor should the path have
    areas of high curvature.

    The extrusion starts from the plane of the object and maintains its orientation relative
    to the path.

    If the path contains segments that are not tangent, the program extrudes the object
    along each segment and then miters the joint along the plane bisecting the angle formed
    by the segments. If the path is closed, the object should lie on the miter plane.
    This allows the start and end sections of the solid to match up. If the object is
    not on the miter plane, the object is rotated until it is on the miter plane.

    Objects with multiple loops are extruded so that all of the loops appear on the same
    plane at the end section of the extruded solid.

    Taper angle

    Specifies the taper angler for the extrusion.

    Positive angles taper in from the base object. Negative angles taper out. The default
    angle, 0, extrudes a 2D object perpendicular to its 2D plane. All selected objects
    and loops are tapered to the same value.

    Specifying a large taper angle or a long extrusion height can cause the object or
    portions of the object to taper to a point before reaching the extrusion height.

    Individual loops of a region are always extruded to the same height.

    When an arc is part of a tapered extrusion, the angle of the arc remains constant,
    and the radius of the arc changes.

    • Angle of taper. Specifies the taper between -90 and +90 degrees.
    • Specify two points. Specifies the taper angle based on two specified points. The taper angle is the distance
      between the two specified points.

    Drag the cursor horizontally to specify and preview the taper angle. You can also
    drag the cursor to adjust and preview the height of the extrusion. The dynamic input
    origin should be placed on the extruded shape, on the projection of the point to the
    shape.

    When you select the extruded object, the position of the taper grip is the correspondent
    point of the dynamic input origin on the top face of the extrusion.

    Expression

    Enter a formula or equation to specify the extrusion height.
