Create and Edit Bolt and Pin Connectors (VBA)

This example shows how to:

  • add a bolt connector to the Connections in a SolidWorks Simulation static study, using persistent reference identifier (PIDs) for entity selections.

  • change the bolt connector's default values, apply library material, and set pre-load.

  • edit an existing pin connector.

The model used in this example had four extrudes (three bosses and one cut resulting in four holes), a static study with a Pin Connector-1 connection, and looked like this:

     

NOTE: To get persistent reference identifiers (PIDs) for model selections, you can use pidcollector.exe or IModelDocExtension::GetPersistReference3.

'----------------------------------------------------------------------------

' Preconditions:

' 1. Add the SolidWorks Simulation as an add-in

'    (in SolidWorks, click Tools > Add-ins > SolidWorks Simulation).

' 2. Add the SolidWorks Simulation type library as a reference

'    (in the IDE, click Tools > References > SolidWorks

'    Simulation version type library).

' 3. Model shown is the active document in SolidWorks.

' 4. Modify path to solidworks materials.sldmat if needed.

' 5. Run the macro.

'

' Postconditions: A bolt connector called Counterbore with Nut-2

'    is added to the study.
