1.6.1.4.5. Auto Classification

Using the Wizard functionality a process pipeline can be set up very easy in PLM Synchro. In a second step, it can be modified for different purposes by modular applicable nodes.

The Auto classify node provides a clear input dialog to create a set of rules by which you will achieve an auto classification of your company parts.

The following exemplary figure shows how to perform assignments into the created classes with the help of geometrical similarity analysis. As further methods assignments can be performed by using topological attributes and VBS scripts.

In the following, the procedure is explained.

  1. Make sure that you have a working base pipeline how it can be easily created with the Wizard.

  2. From Available filters, drag the Auto classify node on the connection between Conversion and Structure Node.

    Insert "Auto classify" node into pipeline

    Insert "Auto classify" node into pipeline

    Perform following adjustments:

    • Adjust the Document Path:

      $IMPORT_PATH./$DOCUMENT_NAME.

      Structure Node - adjustment "Document Path"

      Structure Node - adjustment "Document Path"

  3. Select the node Auto classify node and in the Node Editor, click on the ... button.

    -> The dialog box Edit rule tree is opened.

  4. In the dialog, create a class structure by which you want to classify your company parts.

    1. In the toolbar, click on Create Class and then in the tree, on Add class.

      -> Just created classes first will show New Class.

      Click into the button and rename it accordingly.

    2. In this way create all required classes and subclasses. The following example does not have subclasses.

    3. Click on Add rule or Add group of rules:

      • Add group of rules: Adds a group of rules, which can be connected by AND or OR condition. Afterwards enter the single rules (see next point).

        AND / OR

        AND / OR

      • Add rule: The options Attributes, Geometric and VBS are offered.

        "Add rule" selection options

        "Add rule" selection options

        When selecting one of the options the corresponding input dialog is opened (see below).

      • Attributes: The classification is made by using topological attributes.

        In the following, the procedure is exemplified by the option Axis Symmetry:

        1. After click on the option Attributes the dialog box Select Operand is opened.

          Select the option Topological Attribute, choose the desired attribute and confirm with OK.

          Axis Symmetry

          Axis Symmetry

          -> The respective entry is made in the dialog Edit rule tree.

        2. Choose the mathematical comparison operand (==, <, >, etc) and then, in the next input field, click on "Click to select operand".

          Click to select operand

          Click to select operand

          -> The dialog Select Operand displays again.

        3. This time the option Direct Value is preselected.

          In the list field, select the desired value and confirm with OK.

          Direct Value

          Direct Value

          -> Now the complete condition is entered.

          If the part to be classified is axis-symmetric, it fulfills this criterion of the class "Screw".

          If the part to be classified is axis-symmetric, it fulfills this criterion of the class "Screw".

      • Geometric: Selection of a part by which the similarity of the part to be classified is calculated.

        1. In the Explorer, select the comparison file.

          Selection comparison part

          Selection comparison part

        2. In the list field, select the correct file format (in the case of STEP this is STEP file input).

          Selection of file format

          Selection of file format

        3. Optionally, you can activate the option Extended Settings. Confirm with OK.

          Import options for format STEP file input

          Import options for format STEP file input

      • VBS: You can load a VBS file in the Explorer.

    4. Start the pipeline.

      Start pipeline

      Start pipeline

      -> If there are possible assignments in the single classes, they are automatically created as directory; otherwise the read in parts will appear in the directory "unclassified".
