Autodesk Revit Architecture

[#1]

I have noticed the added parameters of 'extensions.buffer1,extensions.buffer2,extensions.buffer3,...etc' after having installed subscripitons advantage tools.

1) Is there a way to tell which user id created the parameters?

2) How are they use, I have not seen them filled in at any points?

3) How do we delete them once they are in a Project, or can we?

Thanks

These are shared parameters automatically created by the Revit Extensions (the source file can be found at C:\Program Files\Common Files\Autodesk Shared\Extensions 2012\Products\Revit\REXParams.2012.txt). These parameters are used internally by the Extensions, so I would not recommend removing them.

I hope this helps!

Katie,

Thanks for the reply. I would still like to know if there is a way to tell what User id and Date it was created.  Ultimately I want to track the use of these parameters. I dont necessarily want to have to take all Extensions off all computers. 

For instance if I am a Subcontractor using the Extensions for a Client who is not, will my machine populate the Extensions Parameters into their model?  If so How do I clean them up? 

Or if I am a  BIM Manager using the tools to asses a model in my office how do I get the extensions parameters out of the model when I am done and we are submitting the model?
