A Visio Logic Gate with Logic

I was recently asked how I would approach improving the Logic Gate 2 in the Circuits and Logic template, on the Analog and Digital Logic stencil. Well, this had resonance with me because I had often wondered why these shapes were not smarter than they are, so I looked more deeply into the shape construction to see how the Logic Gate 2 shape works, and how it could be improved so that the values of the inputs could be set and the logic applied to provide the correct output value. Eventually, similar improvements can be applied to all of the master shapes so that the connected logic diagram responds to input value changes.

The Existing Shape

The Logic Gate 2 shape has Shape Data rows to provide some configuration. Firstly, you can change the number of inputs from 2 to 5, and the number of outputs from 1 to 3:

Things that Should be Easy

Every so often (too often in the IT industry) I encounter things that should have been very easy to do but turned out to be far too complicated. My favorite topics include SharePoint, .Net development, and software architecture, especially distributed systems.
