Thank you for the suggestion, but this is an artificial limitation in AOEN because they use a library that is outdated regarding PDF printing. They cannot create PDFs in the latest formats above 1.4, and therefore there are limitations on the dimensions of the PDF file. Newer PDF formats have significantly larger dimension scaling and do not have this artificial limitation.
The same largely applies to all other forms of “export” as well.
They have been aware of this problem since version 2, and I notified and asked them for a fix when version 3 was released, they have never done anything with this problem, even though all they need to do is to use another library for the pdf svg export… lots of options out there, even a few open source free variants they can use.
