Do you have a 'start part' ? Do you know how to create parameters in a model?
The only way I can think of doing it is to create a parameter in the model called File_path and give it a value of whatever your file path is and then on your Formats, type in &file_path (put it anywhere on the dwg, including the table) and then when you create a new dwg, it will automatically show up.
Yes, I use start parts, and i'm very comfortable working with parameters in models, and associating them to the drawing. I do this quite a bit actually, but I wanted something that wouldn't require me to update the parameter manually every time I moved a file or something. I was hoping that there was a system parameter in the drawing such as &dwg_name or &scale that I wasn't aware of, and that somehow it could pick up the working directory. It seems to me that this would be easy enough for Pro/E to do, but I can't seem to find this elusive parameter (if it exists).
As far as I know, there isn't one. If there was one, it would probably be under Table, enter text <report sym>, model information and there isn't. I went through all of them and didn't see anything. Your right, it would be very easy for them to do that.
