Yes that's correct. The one template could be metric or imperial aswell as it is the styles used which dictate dimension types etc. The ilogic I use changes the sheet size, border and title block and if swapping to or from A0 size sheets it also changes the active style to account for different text heights.
I have attached the template file in the end as I could think how to strip out the iLogic code and the iLogic form.
The form is instigated by the iTrigger icon and relies on a pre-defined user parameter which is a list of sheet sizes. Once selected the code looks at the user parameter and swaps out the border and title block accordingly. I'm sure the code could be a lot neater but it works so thats good enough for me
Template will help me get going in the right direction, I will marked this thread as solved, as it seems that I will be able to create one template file and use iLogic to customize the template to specifics.
Once I get into the iLogic part, I will most likely need some assistance (programming skills are weak) but I will post a new thread in the customization forum.
