Hi,
Is Possible:
Check this:
Dim oTransMgr As TransactionManager
Dim m_inventorApplication as inventor.application
m_inventorApplication = thisapplication
oTransMgr = m_inventorApplication.TransactionManager Dim oTrans As Transaction oTrans = oTransMgr.StartTransactionForDocumentOpen("DEscription Of the Command") 'YOUR CODE HERE 'YOUR CODE HERE oTrans.End()
The rule or command can now simply being undo with the undo button in Inventor or Ctrl+Z

Hi @Anonymous,
Hoping that following iLogic code would help.
Dim oCommandMgr As CommandManager
oCommandMgr = ThisApplication.CommandManager
' Get control definition for the line command.
Dim oControlDef As ControlDefinition
oControlDef = oCommandMgr.ControlDefinitions.Item( _
"AppUndoCmd")
' Execute the command.
Call oControlDef.Execute
Please feel free to contact if there is any queries.
If solves problem, click on "Accept as solution" / give a "Kudo".
Thanks and regards,
