Delete Revit default parameters or allow us to delete them

[yann_geay]

Some default Revit parameters are useless and morether harmful for a well done BIM project.

Here is an example with the foundation family template :

Revit don't allow to create our own strip-like footing (wich is already scandalous). So, if i want to create my own strip-like footing (because my foundation is composed of two distinct layers), i have to build it with the template of "Foundation".

But there is already default parameters in this template (width, length, thickness). This obviously mess with my shared parameters, but morether, we can't change them from "type" to "occurence" ! Which mean, i have to create one type of foundation per wall of different length i have in my project, only to have "strip-like footing" in a "Foundation" category !

I've seen a lot of absurd things in Revit, but this is the first time I've seen such a big BIM consistency error.

Hoping this will be fixed soon.

What are the two layers that your wall footing is made of? 

My guess is that possibly the bottom layer is stone (?) - if this is the case, then I think I would still model the wall footing as the one element that has the dimensions of the stone and the concrete. Then, in sections or details add a detail component to represent the stone (or whatever) layer.

The second layer is a diferent kind of concrete.

But even if it was a layer of stone, it's not "BIM friendly" to draw, as a detail component, something that we want to be mesurable. 

By doing this, I am ignoring a major use of BIM (and 3D modeling). I also waste a lot of time on something that could have been extremely simple if Revit did not impose excessive limitations, without much real interest.

(Here, imposing default parameters in a template is a limitation, and not the lack a tool that is not yet intended in the software.)
