Does any ANSI format (A, B, C …) exist in Layout? If not, how to create them?
Do you want ANSI paper sizes? At least some of them are selectable in Document Setup>Paper.
You can manually set the paper size to whatever you want and create your own custom template. Start a new file and change the paper size to suit. If that’s the only change you need to make to create your custome template use File>Save as template.
You might want to create your own custom title block, format text and dimensions, establish layers, add logo images and boilerplate text, etc. before you create the template.
Ok, thank you for your reply.
