I've read various threads about this, but none are quite what I'm looking for. As with many other people, I would like to change my drawing template for around 150 existing drawings.  I could go through each individual drawing and 'reload' but I was hoping to automate it. It seems that a macro would be ideal, I've tried a few from these pages but they don't work for me ('Change_Sheet_Format.swp' does formats, not templates, 'copydocoption-1.9.0.xls' doesn't change the template. 'Batch Process' would probably work, but seems quite expensive just for the single operation I require). I also tried recording my own macro - just mouseclicks - but I get a “Runtime error ‘450’ wrong number…….” error, and I'm completely VBasic illiterate so I don't know how to fix this error. I'm on SW2007 which also appears to make this operation more difficult. Any help gratefully appreciated.

TIA
