Hi Pendean,
I'm going to try answer all your questions the best I can. Keep in mind I'm an autoCAD user, playing with variables, internal settings is not my forte.
First, I'd mention that this template has worked for us since quite a few years/releases now. Only now with 2026, we have this situation.
- I don't understand why you had to recover this file.
- This template has the border as a dynamic block that contains several border formats, both metric and imperial. If I remember correctly, when I created that template, I had problems to have the border printed correctly. I had found that having the 0,0 on the left solved that problem. Also, the title block is a dynamic block too, and all texts are a block. A block that always stays at that point. That is also why I have my 0,0 there.
- About the Pdf driver, I have no idea... this is what comes with Autocad after installing it.
- The portrait Vs Landscape, I don't know why you have that. We pick the border size, ie A0 Portrait, then we change the page setup accordingly.
- We have different leader styles (common, with bubble, with elongated bubble etc... and both metric and imperial.
- To create new Mleader, we select leader style, then in paper space, place one leader and then pick the command "add leader", if needed.
Hope that helps
