I am working with a large, complex electrical schematic (the PDF is 300+ pages, around 80Mb) that we recieved from a 3rd party. The PDF is supposed to have links that navigate directly from the end of a circuit shown on a given page, to where that circuit continues on another page (which may be in another system/circuit dozens of pages away). There are hundreds of circuit ends that are linked.
These "links" are visible on the page (in the Content panel they appear under Annotations), but they are apparently not standard Acrobat links, I cannot edit them, and when I click on they don't link anywhere.
When clicked, the only thing that happens is the visibility toggles on/off (although the mouse cursor always shows if there is a link to click if hovered over).
See what they look like here when I hover over:
This wire end should link to the corresponding end on the page labeled 45/2.
I have another schematic from the same 3rd party, and these odd links do actually work (appears to link to how the bookmarks are named? This is the primary difference between the working and non-working files).
I suspect that this is ultimately an issue with how the PDF was exported from the CAD software the 3rd party used originally, but it may not be possible for me to have them correct this. I would like to get these links functional because manually recreating the links would take ages. I don't have access to the original files, so I cannot get any other PDF output the from CAD software.
I will also note that these PDFs generally freeze and crash often, so I'm open to any interpretation of what is happening here, and potential ideas for fixes.
