Fire Undo and Redo Pre- and Post-notifications in Assembly Document (VBA)

This example shows how to fire Undo and Redo pre- and post-notifications in an assembly document.

 

Module

' ******************************************************************************

' Preconditions: Open:

' <SolidWorks_install_dir>\samples\tutorial\smartcomponents\stepped_shaft.sldasm.

'

' The base-plate<1> component is selected and then hidden, and

' pre- and post-notifications are fired indicating that an

' Undo has occurred. A Redo is performed and pre- and

' post-notifications are fired for it. Finally another Undo

' is performed (and pre- and post-notifications are fired)

' so that the assembly document returns to its just-opened state.

'

' Postconditions: None

' ******************************************************************************

Dim swApp As SldWorks.SldWorks

Dim swModel As SldWorks.ModelDoc2

Dim swModelDocExt As SldWorks.ModelDocExtension

Dim swAssembly As SldWorks.AssemblyDoc

Dim boolstatus As Boolean

Dim swAssemblyEvents As Class1

 

Sub main()

 

Set swApp = Application.SldWorks

Set swModel = swApp.ActiveDoc

Set swModelDocExt = swModel.Extension

 

' Event notification

Set swAssembly = swModel

Set swAssemblyEvents = New Class1

Set swAssemblyEvents.swAssembly = swApp.ActiveDoc

 

' Select a component and hide it

boolstatus = swModelDocExt.SelectByID2("base_plate-1@stepped_shaft", "COMPONENT", 0, 0, 0, False, 0, Nothing, 0)

swModel.HideComponent2

swModel.ClearSelection2 True

 

' Undo hiding of the component

swModel.EditUndo2 1

 

' Redo hiding of the component

swModel.EditRedo2 1

 

' Undo hiding of the component

' so that model document is unchanged

swModel.EditUndo2 1

 

' Rebuild the model

swModel.ForceRebuild3 True

 

End Sub
