Writing a Path Finder Macro

A macro is a series of functions, written in a scripting language, that you group in a single command to perform the requested task automatically. You can for example use a macro to automate the generation of an automatic path finding.
This task shows how to use the automatic path finding functionality in batch mode, which means you are going to record an interaction sequence in a macro.   This task also lists the macros that can be edited.
Open the mastervac.CATProduct document.

  1. Select Tools > Macro > Start Recording.

    The Record macro dialog box appears.

  2. In the Record macro dialog box, specify the current macro library or document.

    This means deciding where the macro is going to be stored:
    • in a macro library: the macro will be stored in a directory (or a VBA project if it exists)
    • in a document: the macro will be stored in the current document.

  3. Give a name to the macro, e.g., MacroPF.CATScript.

  4. Click Start to begin recording the macro.

  5. In the specification tree, select Simulation.1.

  6. Click Path Finder from the DMU Check toolbar.

  7. Set the options in the Path Finder dialog box as displayed.

  8. Click Apply to launch the operation.

  9. When done, click OK to smooth the path result.

  10. When this is complete, click Stop in the Stop Recording dialog box, or select Tools > Macro > Stop Recording .

    Your macro is now ready for replay.
    The macro looks like this:
    MACRO EXPLANATIONS
    Language="VBSCRIPT"

    Sub CATMain()

    Dim FittingWorkbench0 As Workbench

    Set FittingWorkbench0 = CATIA.ActiveDocument.GetWorkbench ( "FittingWorkbench" )

    Dim PathFinder1 As PathFinder

    Set PathFinder1 = FittingWorkbench0.PathFinders.Add ( "PathFinder" )

    		  
    PathFinder1.set_SimulationByName "Simulation.1" Name of the simulation selected.
    PathFinder1.set_DoubleParameter "Accuracy", 14.758000 Corresponds to the accuracy value chosen in the Path Finder dialog box.
    PathFinder1.set_DoubleParameter "TranslationStep&qu Corresponds to the translation step value chosen in the Path Finder dialog box.
    PathFinder1.set_DoubleParameter "RotationGain", 2.000000 Corresponds to the rotation gain valuechosen in the Path Finder dialog box.
    PathFinder1.set_IntegerParameter "Repulse", 5790  
    PathFinder1.set_BoxParameter "Box", -205.110550, -1115.599648, -341.661041, 918.198769, 460.187050, 694.402138

    PathFinder1.Compute

    		 You resized the bounding box : the new values are displayed.
    PathFinder1.FillSimulation Insert the above result into the simulation
    FittingWorkbench0.PathFinders.RemovePathFinder PathFinder1

    End Sub

    		  

  11. Open the MacroPF.CATScript document.

    You can edit your macro if necessary. For more detailed information, please refer to Recording, Running, and Editing Macros in the Infrastructure User's Guide.
