I have been contacted by Ed again to let me know that he has encountered issues with the content and he is getting similar reports from others. They haven't been able to get them to work in Revit. A couple of comments posted here and in a thread at AUGI suggest that this first release might better have been termed "Alpha". Ed informs me that he's been told that the folks at Simpson are working on it. I'm sure they'll get the situation sorted out.
The primary objections shared with me so far is modelling excessively and that users need detail component versions of these families as much or more than 3D versions. This is what I was alluding to in my comment about level of detail in the previous POST.
