How can I embed a scale in a PDF drawing?

[IanChap]

I've searched for this many times, and most results seem to tell me how to ignore an embedded scale, or how to temporarily change it. Neither is what I want.

But I believe it's possible to permanently embed a scale in a page. The distance tool states 'Ebedded Scale Ratio', which is invariably blank.

So how exactly do I embed it?

Hi IanChap,

Thank you for reaching out.

Please refer to the information provided in the following help document: https://helpx.adobe.com/acrobat/using/grids-guides-measurements-pdfs.html.

Check if that helps.

If you are looking for other information, let us know how you create the PDF.

Share the Acrobat and OS versions.

Thanks,

Meenakshi

Thanks Meenakshi.

But although there's a lot of useful info there, I don't see how to embed a scale?

It's usually PDF's created by others, which I need to open numerous times, and they don't have an embedded scale. In fact I don't think I've ever come accross one! So I'd like to embed the scale, to avoid having to set it every time I open a drawing.
