Would it work @tabz-nixonkingspan-com to bring all of the files into a Studio Project? Doing so may take some re-training of your end users, but it could work as a way of collecting everything into one central location that can be shared. Others in the group are more familiar with this process.

Re-reading your post a further thought on my previous comment about asking for unlocked copies of the files would be to work this into your qualifications for your services. Be upfront with your needs in your quotes/contract language. Something along the lines of “Customer will provide all required documentation in unrestricted PDF format for incorporation into final project records.” might do the trick. As Civil Site Contractors we include language in our proposal that requires the Customer to provide a CAD file for us to build our survey model from. This saves us a tremendous amount of time and cost when developing our survey models.
