i am having a problem changing an existing sheet to another one new one,

my company has changed logos and as such i need to change the logo on a few of our older drawings,

i can make a new drawing template with what i want and it works great for new drawings,

but i can’t change the old ones, when every i go to Sheet format>Sheet properties>browse it is giving me only the option of finding *.drt, *.slddrt typ files

but when i save the new sheets as drawing templates it saves them as *.drwdot files

when using sw 2008 it was not a problem to change a sheet format, maybe i am missing something

i have attache screen shots of the two file types
