Validating Junctions

You can validate the junction arrangement of the flatten data against the harness data. It helps to compare the flatten data and the harness data for their relative compatibility and the compatibility with the manufacturing process.


Before you begin: Flatten the harness geometry using the Formboard command or open the data flattened using Formboard command. If you open the flattened data , synchronize it with its harness data.
  1. From the Formboard section of the action bar, click Junction Validation .
    The Junction Validation panel appears. By default, the start and end points of the backbone are added as the start and the end points of the path to analyze. The labels, START and END, appear on a selected branch. The branch is colored in pink .
    Note: You can change the end point of the path to analyze.
  2. In the Junction Validation panel, click Finalize.
    In the Junction Validation panel, the following information is displayed:
    • The junctions in the selected path ordered from the start device to the end device in the Junction column
    • The type of the junction between the following possible types in the Junction Type column:
      • Junction with support
      • T-shape junction
      • Arranged junction
      • Non-arranged junction
    • The support instance name part for junctions with support in the Support column. For other types of junctions, NA is displayed.

      The segment from which the junction is analyzed in the selected path in the Primary Segment Path column

    • The position of segments within the different junctions depending on their types is displayed on the right side pane.
    • Commands to reframe and manipulate the segments.
    In the harness data, the selected path to analyze is displayed as below:
    • Big green vectors are displayed at the characteristic points such as devices, supports, junction points, etc.
    • Smaller green vectors are displayed in between the big vectors. The green vector indicates the orientation of the backbone and is normal to the flattened plane.
      Note: The pitch between two consecutive vectors is defined in the Pitch box under Backbone Vector Field, available at Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Manufacturing Preparation > Electrical Manufacturing Preparation > Formboard.
  3. Select the required junction.
    The list of segments organized in the common support of the selected junction is displayed below the table listing junctions. Based on the junction type, the panel displays information as below:
    Type of Junction Columns Displayed
    Junction with support
    • Secondary Segment Path: Displays name of the segments defining the selected junction
    • Electrical Geometry: Name of electrical geometry containing a segment
    • Diameter: Segment diameter value (mm)
    • Segment Position in Support: Segment position in support in (U,V) axis system, V-axis being the filled vector at the entry of the support and the origin is at the support center
    • Ambiguous: Ambiguity status of the segment (If the segment profile crosses the ambiguity zone fully or partly, the segment becomes ambiguous. This segment can be at any side of the backbone, left or right.)
    • Ambiguity Offset: Ambiguity offset or width value around the vector at the entry segment within which any segment is ambiguous

      You can specify the offset width as below:

      • In the Ambiguity zone width box under Junction Ambiguity Zone, available at Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Manufacturing Preparation > Electrical Manufacturing Preparation > Formboard
      • Using the business rule: Junction Ambiguity Zone (EHFTorsion_AmbiguityZone)

    • Network Weight: Network weight of the segment, in other words the number of junctions from the segment end to the rest of its network ends
    If the segment profile is within the ambiguous zone, you can rotate (using Rotate ) segment using the command available in the panel.
    Segment Profile in Ambiguous Zone

    Segment Profile Not in Ambiguous Zone

    T-shape junction
    • Secondary Segment Path: Displays name of the segments defining the selected junction
    • Electrical Geometry: Name of electrical geometry containing a segment
    • Diameter: Segment diameter value (mm)
    • Angle with MFA vector : Angle between the segment tangent at the junction point with the field vector at the junction point
    • Ambiguous: Ambiguity status of the segment

      If the segment center curve is within the ambiguity zone defined by a conic zone around the field vector, it is considered as ambiguous.

    • Ambiguity Angle: The ambiguity zone angle is defined in the Ambiguity zone identification angle box under T-Shape Junction, available at Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Manufacturing Preparation > Electrical Manufacturing Preparation > Formboard
    • Network Weight: Network weight of the segment, in other words the number of junctions from the segment end to the rest of its network ends
    If the segment center curve is within the ambiguous zone, you can mirror (using Mirror )the segment using the command available in the panel. The segment is represented by a square with the segment color and diameter value as width.

    In the harness data, the selected junction is highlighted.

  4. Under Harness, click Reframe to reframe the selected junction in the harness data.

    You can also click Center Tree to highlight the node of the primary segment of the junction in the tree when no segment is selected in the segment list.

    Note: If you click the commands under Flatten, the selected junction is reframed in the flattened data or its node is highlighted in the tree.

  5. After doing the required manipulations, click Close or the Junction Validation on the action bar to close the operation.
