Manage Attributes on the Fastener Reference

  1. Locate the Fastening app standard file (Fst_Standard.xls).

    Tip: You can select Me > Preferences > App Preferences > 3D Modeling > Multi Discipline Engineering > Fastening > General > Standard Management to find the location of the standard file.

  2. Edit the standard file as follows:
    1. Add the "Structure" category in the "FTYP_CLASSATTRCATEGORIES" row.
    2. Insert a new row, "FTYP_CLASSATTRLIST_Structure", and define attributes in it, for example, the "Joint" attribute.
  3. Edit the excel file of the required process type, MIG, for example.
    1. Add the attributes in the "Fst_CLASSATTRLIST" row.
    2. Insert new rows for specifying the values of the attributes. For example, insert a "Fst_CLASSATTR_Joint" row for the "Joint" attribute and specify its value.
    For more information about customizing the fastener standard files, see Fastening User's Guide: Administration: Working with the Fastener Standard and Reference Fastener Type Files.

Create a Fastener Reference

  1. Create a unified bead fastener reference.
    1. Select Add > Content
    2. In the New Content panel, expand Fasteners and select Unified Bead Fastener .
  2. Create a physical product with a 3D shape and switch to the Fastening app.
  3. Instantiate the unified bead fastener reference under the physical product with the Explicit Mode location option, using the Fastener Instantiation command. For more information, see Fastening User's Guide: Instantiating Fasteners: Instantiating Bead Fasteners and Unified Bead Fasteners.
  4. Right-click the unified bead fastener's node in the tree, select Properties, and click Reset instance position to identity in the Position tab.

Create the Fastener Geometry

  1. In the fastener reference, create a parameter and name it 'Reference'.

    This parameter is used to recognize the original fastener reference. During generation of the fastener, the value of this parameter is assigned automatically from the value of the "ResourceIdentifier" keyword in a catalog or classification attribute in a library.

  2. Under a geometrical set, create two surfaces as shown below to represent a dummy pilot and joined part geometry.

  3. Define input geometry.

    Create input features. The input features are replaced with the computed geometries of the pilot and joined parts. There are two methods to replace the input features:

    • Replace the input features with the automatically computed geometry.
    • Replace the input features with the named geometry, using key names.

    Notes:
    • The input features must be aggregated under a geometrical set named "Input".
    • The features must be of the multiple extract type.
    • Input features must respect the following naming convention: (Object Type)_Input_(Numbering)_(Geometry Type)_(Usage)
      • Object Type: Plate or Profile
      • Geometry Type: Face, Edge, ResultFace, or ResultEdge
      • Usage:
        • Comp: to replace the input features with the automatically computed geometry. When using this usage type, the geometry type must be Face.

        • Key: to replace the input features with the named geometry, using key names. For plate, use Top or Bottom. For profile, use Start, End, or from the section keys.

          For more information, see Naming Section Edges.

  4. Define a result geometry for the fastener curve.

    • For the computed geometry, create an interference feature between the input features.
    • For the named geometry, define a curve as required from the input features.


  5. Edit the unified bead fastener reference and change the location option to On Curve Mode and select the curve.
  6. Edit the engineering connection of the fastener.
    1. Remove the RollCurve type constraints
    2. Set the constraints type to User Defined.
  7. Isolate the unified bead reference from the product using the Links and Relations command.
