I have to use several preset sizes that aren't available in the standard Artboard presets. I have saved them as an Artboard Tool Preset but they don't seem to work. Is it me or every time I want to use what I need as a standard artboard preset size that isn't provided by Adobe, I will need to manually set the artboard size?
OK. I just figured out. I need to create the new artboard size when creating a new document to save it as a preset to be available within the document for adding artboards later. Otherwise it can not be saved. It can only be saved on creation as a new document. Strange way to work.
