Question: I am creating a model in ArcMap 10 and I need to use the Buffer Wizard tool to create multiple buffers within a polygon feature class. The problem is, I can't seem to place the Buffer Wizard within my model. I can place the Buffer or Multiple Ring Buffer command into my model, but they don't automatically populate a FromBufferDistance or ToBufferDistance value for each ring like the Buffer Wizard does. I need these values for a field calculator equation later in the model. I may be able to get by with just using the Multiple Ring Buffer tool, but it would be much more efficient to use the Buffer Wizard.

If I am unable to include the buffer wizard in my model, is there a way to run it in a script? This seems unlikely, but worth a try.

Answer: 
The Buffer Wizard (and other wizards like the GeoStatistical Wizard) is a UI functionality. 

There is no scripting/programming API for it in any version of ArcGIS 9.x or 10.x, and since it is not a geoprocessing tool so it cannot be used in ModelBuilder.
You could try using an iterator in ModelBuilder for buffering multiple distances.
