Create Hidden Undo Object Example (VBA)

This example shows how to create an Undo object that is hidden in the SOLIDWORKS Undo list.

'-----------------------------------------------------------------------------
' Preconditions: Ensure the part template path exists.
'
' Postconditions:
' 1. A part with four sketches is created.
' 2. One sketch is extruded.
' 3. A hidden Undo object, API Undo, is created with two extrusions.
' 4. One sketch is cut extruded.
' 5. The following items appear in the SOLIDWORKS Undo list in this order:
'    a. Extruded Cut
'    b. (API Undo, hidden from view)
'    c. Base
'
' NOTE: If you select Base in the SOLIDWORKS Undo list:
' 1. The base boss created before the recording of the hidden API Undo object is undone.
' 2. The two bosses created during the recording of the hidden API Undo object are undone.
' 3. The cut extrusion created after the recording of the hidden API Undo object is undone.
