Thanks for the reply. I did have greater success selecting and copying an 'isolated' image from the PDF (opened it in Affinity Photo IIRC), but it was not a vector, which is what I need. The layout in the vector files is really weird, as none of the images within the smaller panels appear to be 'locked', or available as a separate image or even as a panel group. When I zoom in, none of the lines connect, though they appear solid when not zoomed, and there are little boxes at the end of each line, which if selected, move the line.
