LOFT-Command

LOFT (Command)

    LOFT (Command)

    Creates a 3D solid or surface in the space between several cross sections.

    Find

    Creates a 3D solid or surface by specifying a series of cross sections. The cross
    sections define the shape of the resulting solid or surface. You must specify at least
    two cross sections.

    Loft cross sections can be open or closed, planar or non-planar, and can also be edge
    subobjects. Open cross sections create surfaces and closed cross sections create solids
    or surfaces, depending on the specified mode.

    When creating surfaces, use SURFACEMODELINGMODE to control whether the surface is
    a NURBS surface or a procedural surface. Use SURFACEASSOCIATIVITY to control whether
    procedural surfaces are associative.

    You can use the following objects and subobjects with LOFT:

    Objects That Can Be Used as Cross Sections

    Objects That Can Be Used as a Loft Path

    Objects That Can Be Used as VCades

    The following prompts are displayed.

    Cross Sections in Lofting Order

    Specifies open or closed curves in the order in which the surface or solid will pass
    through them.

    Point

    Specifies first or last point of the lofting operation. If you start with the Point
    option, you must next select a closed curve.

    Join Multiple Edges

    Handles multiple, end-to-end edges as one cross section.

    Mode

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

    Continuity

    This option only displays if the LOFTNORMALS system variable is set to 1 (smooth fit).
    Specifies whether the continuity is G0, G1, or G2 where the surfaces meet.

    Bulge Magnitude

    This option only displays if the LOFTNORMALS system variable is set to 1 (smooth fit).
    Specifies a bulge magnitude value for objects that have a continuity of G1 or G2.

    VCades

    Specifies VCade curves that control the shape of the lofted solid or surface. You
    can use VCade curves to control how points are matched up on corresponding cross sections
    to prevent undesired results, such as wrinkles in the resulting solid or surface.

    • Intersects each cross section
    • Starts on the first cross section
    • Ends on the last cross section

    Select any number of VCade curves for the lofted surface or solid and press Enter.

    Path

    Specifies a single path for the lofted solid or surface.

    The path curve must intersect all planes of the cross sections.

    Cross Sections Only

    Creates lofted objects without using VCades or paths.

    Settings

    Displays the Loft Settings dialog box.
