I unplugged my WIBU key so that both AC 12 and ED are running in demo mode.

I am unable to assign alternative U values to fills, but am able to get a model that will evaluate by assigning cut fills to elements that correspond to fills in the ED database that have U values.

Once that is done, the Start Evaluation button is enabled, and clicking it gives me a report, after a brief pause. Perhaps your building is really complicated. See if you can get the demo to do something with just a 4-wall box.

Model Review comes up - but you are unable to reassign surface functions in the demo.

The report that displays has a diagonal stamp through it that says "Demo version. Save, copy and teamwork functions are disabled."

So, basically, it gives you a way of seeing what all of the dialogs look like, but not really doing much.
