Working on a Macro that has several Userforms.

I can find how to have an auto closing Userform for excel but it isn't working for soldiworks.

I'm finding code like this:

Sub show_UserForm()

Application.OnTime Now + TimeValue("00:00:15"), "close_UserForm"

UserForm1.Show

End Sub

Sub close_UserForm()

Unload UserForm1

End Sub

Or:

Private Sub UserForm_Activate()

  Application.Wait = (Now + TimeValue("0:00:30"))

  Sheet1.Cells(1, 1) = "Yes"

  Unload Me

End Sub

But I can't get it to run with solidworks Macros
