Version 20 corrects a glitch, from v18, regarding the arity-changeability of the unary fact type shape. It also includes instructions on how easiest to upgrade a Visio drawing that used the template for v17 or later, to a later version's stencil and shapes (it is not sufficient simply to open, and start using, the later-version stencil). Also new, as of version 17, are a discussion of how to get Visio 2007 and 2010 to enable macros automatically that are in Visio solutions or documents in specific folders on your computer, and a discussion of how to install the solution in Visio 2010.
The ORM2_Draw2 Visio stencil for ORM diagrams is an updating and upgrading of the ORM2_Draw Visio stencil which itself resulted from ORM stencil development by various people, including Peter Ritson, Terry Halpin, and Andy Carver. It is an updating in that it updates (for Visio 11, 12, and ff.) the Table shape, and includes the deontic constraints and value-comparison constraints. It is an upgrading in that it adds built-in shadowing (for fact types and object types), built-in text-arrows (for fact types), built-in constraint-connectors, and some adjustable-arity fact types, as well as several relatively minor upgrades and fixes, including internal and external frequency constraints. Since version 1, many other improvements have been added (see the readme file).
Version 1's stencil (.vss) and template (.vst) files were created, based on ORM2_Draw, during the Winter of 2008-9, by Andy Carver with the help and supervision of Dr. Terry Halpin. The files have been tested and used pretty extensively in both Visio 10 and Visio 12. A readme.txt file is included.
