Family templates, which one is the good one ?

A lot of people get lost when it's time to choose the right family template. In fact, Autodesk added new family templates with the lastest releases. A lot of these new templates don’t add anything special to the family behavior in the project. The only differences between the generic model template and the structural foundation template, for instance, are the category and family parameters already set. This means that I can do the same family using the generic model template. From a new user's standpoint, having this long list of template is more a headache then a real boost.
I decided to do this diagram to help users understand which template to use. It's a first draft but before spending too much time on that I'd like to have some input and feedback from people on which questions I should add to this decision workflow. Let me know your thought !

Demistify project, family, type, instance and shared parameters

I have to explain too often the relationship between parameters, were they are stored and what they control. I decided to create this little diagram to illustrate how it works. A picture worth a thousand words!

Wall foundations

For those of you who doesn't know yet, I have been asked last week why some of my wall foundations width have a different behaviors when I change the wall thickness.

As you can see on the first screenshot you have a structural usage parameter under the type proprieties dialog box of a wall foundation. when it is set to Bearing you have acces to a width parameter wich is the overall footing width.

On the second picture you have the parameter set to Retaining and you can see that the width is now set according to the outside face of the wall and controlled by 2 paramters Toe and Heel wich is not very usefull if you need to schedule your footing's width.
