There is no concept of sets like this in the document presets, but you might get what you are after by using Templates (.indt files) instead. You could set up folders with multiple versions for each size, or a single file with different master pages for each configuration.
A side benefit of templates is that in addition to the page size, margin and columns info stored in the preset you can include multiple master pages, all of the predefined styles and swatches for your typical use of that template, and static information that should always be included in documents made from that template. Templates are a lot more powerful than just a document size preset.
Create a new document and choose custom as the document size. Fill in the size requirements, give it a name and choose add,
bob: if i created a series of custom sizes..indesign would just list them in a series..correct?? there is no way to organize them?? if there is no way to organize them into specific publications....the result would be list of approx 300 different column sizes to scroll through. (again i don't know how InDesign works other than tinkering)
peter: "single file with different master pages for each configuration". i watched a video on creating templates etc. InDesign..while versatile..doesnt make thing easy lol. Not trying to publish book..just create simple advertising docs on the fly. I guess its a learning curve?? Not familiar with creating documents in this manner.
it would be file new then apply templates from the pages menu??
I would think multiple size selection is something that could be scripted into InDesign?? no clue
To use templates it's File > Open... then navigate to where the template file is stored, which can be anywhere, so you can create a master template folder, then subfolders for clients or types of ads or whatever.
Templates have a .indt file extension which triggers ID to open an Untitled copy by default so you don't accidentally overwrite them with an actual document, but essentially you can just change the extension on any .indd file to .indt and it becomes a template, and vice versa.
I want to set the size of a document, to be created by my Plug-In eighter before creation ore diectly after document creation.
May you give me a hint, how to solve that problem?
Like most users on this forum, I'm a designer, not a developer, and I know nothing about creating plugins. Apparently Adobe has decided to kill the forum dedicated to the SDK.
