Although I understand why people think this is not worth putting time in it, I believe that doing things nice, clean and neat with just the little things, it will help you be nice, clean and neat with the big things.
If you don't see any value in a nice business template, do you like naming conventions?
Or are you not interested in putting things in different layers?
Are you one of those people who don't care much about updating geometry, if one can update the dimension as well?
Or what about file naming, like "design today.dwg", "version 2 (1).dwg", "version 2 better.dwg", etc.
And there are people who don't comment code and name every control just Textbox1, Textbox2, Button1, etc (probably not on this forum)
On the other hand, not everybody should be a hair-splitter
Just be effective with a little sense of tidiness... But I do like having a nice business template.
