Today I received a shiny chrome 4gb USB key from CSR containing their Gyprock Revit files (currently, 48 RVT files with a single wall type contained in each).

I had followed the instructions at this link:
Gyprock : The Gyprock™ Revit Family

You could also download this PDF form (click the link then File – Download), fill it out and email to designlink@csr.com.au
