Edit or Debug SOLIDWORKS Macro

Edit or debug SOLIDWORKS macros using Microsoft VBA or Microsoft VSTA.


  • SOLIDWORKS 2018 offers Visual Studio Tools for Applications (VSTA), impacting how VB.NET and C# macros are developed and run in SOLIDWORKS 2018 and later.

  • When debugging Microsoft VSTA macros with user-interface components such as PropertyManager pages, manipulators, or other objects that use events or handler objects, the debugger must continue to run after the main() method of the VSTA macro exits. Either deselect the user-interface system option Stop VSTA debugger on macro exit (located on the Tools > Options > System Options dialog) or set swUserPreferenceToggle_e swStopDebuggingVstaOnExit to false to keep the debugger running after the main() method of the Microsoft VSTA macro exits.

  • To automatically edit a macro after recording it, click Tools > Options > Systems Options. On the General tab, select Automatically edit macro after recording and click OK. This setting is persistent across SOLIDWORKS sessions unless you selected to save a just recorded macro as SW All Macros Types (*.swp, *.csproj, *.vbproj). This setting has no effect when you select to save a macro as multiple macro types.

  • If you recently edited the macro, you can select it from the menu when you click Tools > Macro. This menu lists the last nine macros that you edited.

To edit or debug a SOLIDWORKS VBA macro:

  1. Click Edit Macro on the Macro toolbar, or click Tools > Macro > Edit.

  1. In the dialog, select SW VBA Macros (*.swp) in Files of type (selected by default).

  2. Click Open.

  3. NOTE:
    You can also edit .swb files, which are older-style SOLIDWORKS macro files. When you run or edit a .swb file, it is automatically converted to a .swp file.

      • Dim Part As Object

      • Dim boolstatus As Boolean

      • Dim longstatus As Long, longwarnings As Long

      • Dim FeatureData As Object

      • Dim Feature As Object

      • Dim Component As Object

    • Delete all lines of code that change the view.

    • Delete all IModelDocExtension::SelectByID2 calls appearing immediately before IModelDoc2::ClearSelection2 calls. However, do not delete IModelDocExtension::SelectByID2 calls appearing immediately after ModelDoc2::ClearSelection2 calls.

    • Delete all IModelDoc2::ClearSelection2 calls appearing immediately before IModelDocExtension::SelectByID2.
