I would suggest looking at spec. ASME Y14.1-2005
It has dimensions in it for titleblocks.
We did that and once our titleblock was created then we populated it with
custom properties so the title block is always populated based on the info filled out in the part.
This way no one has to make changes to it.
Hope this helps.
Did you have a look at the one that comes with SW installation under template folder. You can always modify that and save as your standard template.
I did have a look and I'm thinking of modifying the A3 sheet available but i was just wondering if anyone had any good ones of their own. As i said were' looking to update ours and want to add in general tolerances, bend radii etc. The one on solidworks seems like a good starting point though.
solidworkstemplates.com has downloadable templates.
