Summary

Use two sections to create a 3D body that is a parent feature.

 

How to Run

  • Ribbon Menu > [Feature] Tab > [Generate] Group > Loft > Face

 

Explanation

Create Parent Feature

Use two sections to create a 3D body that is a parent feature.

  • [Select Profile]
    Select the starting and ending sides to use for 3D body creation, respectively.

  • [Select Path]
    Select the creation path to use for 3D body generation. If the user does not select a path, the path is automatically set in the direction that connects the two sections to the shortest path.

  • [Loft Type]

    • Mitered Corner : If set to Off, a 3D body is created along the shape with the fillet applied to the selected path, and if set to On, a 3D body is created along the selected path.

If the user selectsthe same start face, end face, and path, and set the Mited Corner option to On/Off, the shape of the 3D body that is created in the form shown above will be different. If set to Off, a 3D body is created along the shape with the fillet applied to the selected path, and if set to On, a 3D body is created along the selected path.

 

  • Corner Zone
    Sets how path edges are connected. Each example is shown in the figure below.

 

 

  • Segment : Create a profile at the midpoint of the path and sweep in both directions to create the final shape. The user may also create features that differ from the results of a single sweep.

  • Compact : Create the final shape by making the edge as short as possible. Depending on the profile, a stepped feature may be created, such as a staircase.

  • Mild : Create a final shape by making the edge longer than the Compact option.

 

  • Reference Segment
    Set the criteria for calculating the profile to be used for connections at the edge of the path.

    • Front Segment : Use the start profile as the basis for the calculation.

    • Back Segment : Use the end profile as the basis for the calculation.

  • [Adjust Profile]
    Adjust the orientation of the rofile.Start profile and end profile can be adjusted separately.

    • Parallel to Reference Axis : Sets the orientation of the profile placement in the Z-axis direction of the entire coordinate system.

      • Off : Maintain current direction.

      • On : Rotate the profile in a direction parallel to the entire coordinate system Z-axis.

    • Current Angle : The current angle at which the profile is placed based on the path is automatically output.

    • Skew Angle : Enter the rotation angle of the profile for the Local YZ plane direction of the path.

    • Horizontal Fit : In the process of regenerating the shape according to the input Skew Angle, set the extension method of the Y-direction edge of the path.

      • Natural : Extend while keeping the curve of the edge natural.

      • Vertex Tangent : Profile vertex in grafting in the direction of the line extend the edge.

      • Path Tangent : Extend the Edge by applying the tangential direction of the path to all Vertex in batches.

    • Vertical Fit : In the process of recreating the geometry according to the Skew Angle entered, set the extension of the Z-direction Edge of the path.

    • Additional Angle : When set to On, the relative value from the selected initial state reflects the Skew Angle. And when set to Off, the Skew Angle entered as an absolute value is reflected.

 

Vertex Matching is a process of setting how to connect the Vertex in each section when the shapes of the Start Profile and the End Profile are different.

 

  • [Vertex Matching]
    Sets the Vertex connection scheme for the start and end sections.

Reference - General Member > [Vertex Matching]

 

Vertex Matching for all points follows the method set by Variation (Default) by default. However, if the user sets a specific path to a particular Vertex through the Variation (User) function, the method set in the Variation (User) function will be applied first.

Variation (Default)

  • [Variation Origin]
    In the process of applying the Shape Variation property, select the location of the baseline for the deformation.

 

  • [Default Shape Variation]
    Sets the order and type of the line that connects the Vertex.

  • [Option]

    • Keep Profile Orientation : Maintain the orientation of the profile regardless of the direction of the path.

 

 

Variation (User) - Keep Profile Vertex (Off)

Use the User-Defined Variation option to create a Loft object.

 

  • [Select Vertex]
    If the Guide Wire point of view is not on the Start Profile, select the Vertex on the Start Profile to change its position to create the feature.

    • Master Vertex : On the Start Profile, select the Vertex to move to the same position as the point in the Guide Wire.

    • Slave Vertex : Select the Vertex the user wants to move with when the Master Vertex moves for feature creation on the Start Profile.

  • [Select Guide Wire]
    Select the path to use when creating the 3D body.

  • [Option]

    • Min. Segment Length : Enter the minimum split length. The length of the segmentation is set to be greater than the length entered.

 

 

Variation (User) - Keep Profile Vertex (On)

Creates a Loft object using the User-Defined Variation option (the selected Start, End Profile is fixed)

 

  • [Global Effect]
    Sets how the Guide Wire is applied during the Vertex Matching process.

    • None : The user can select multiple GuideWire and utilize GuideWire only for Vertex to which GuideWire is connected.

    • Translation : The user can select only one Guide Wire and apply it to all Vertex connections by moving it parallel.

    • Rotation : The user can select only one Guide Wire and rotate it to apply to all Vertex connections.

    • Reflection : The user can select only one Guide Wire, which moves symmetrically and applies to all Vertex connections.

  • [Select Guide Wire]
    On the screen, select the connection curve of the feature the user wants to apply to the Vertex Matching Set.
