To fix it so that the 2012 Python shortcuts would work in 2013 SP1, we did an Undo on the changes to the siutils module. So now, scripts that use the 2012 siutils shortcuts will work unchanged in 2013 SP1.

We moved all the changes [which included some bug fixes] to a new module named sipyutils. When you use the Syntax Help in the 2013 SP1 script editor, you’ll get these shortcuts:

#
# Softimage 2013 SP1 shortcuts
#
from sipyutils import si		# win32com.client.Dispatch('XSI.Application')
from sipyutils import siut		# win32com.client.Dispatch('XSI.Utils')
from sipyutils import siui		# win32com.client.Dispatch('XSI.UIToolkit')
from sipyutils import simath	# win32com.client.Dispatch('XSI.Math')
from sipyutils import log		# LogMessage
from sipyutils import disp		# win32com.client.Dispatch
from sipyutils import C			# win32com.client.constants
from sipyutils import logf

si = si()
logf( "Version %s has %d commands", si.Version(), si.Commands.Count )

Note that you get an si shortcut that is a function, so you have to call it to get the actual XSIApplication object.

In summary:

• 2012 shortcuts work unchanged in 2013 SP1

• 2013 shortcuts won’t work in 2013 SP1. This line will give you an error:

  si = si()					# win32com.client.Dispatch('XSI.Application')
  

  You have to either comment that line out, or edit siutils and uncomment the definition of si(). Or just switch to using the new sipyutils shortcuts.

• 2013 SP1 shortcuts come from the new sipyutils module. The si shortcut is a function, call the function and bind the result to an identifier eg si = si().

For reference, here’s the shortcuts from previous versions:
