To understand your issue, i created 3 file fields in a table to manage documents (tbl_DMS). All 3 fields do exactly the same job.
Drawer 1 has limits set for max mb size, file type allowed and image size/quality etc…
Drawer 2 is the same thing but no parameters set but download link is set to field value.
Drawer 3 is secure. Custom value ‘Download’

Im guessing, floorplan implies you want to put the file links into each grid location of your floor plan. I have seen SoP documents arranged in a pyrmid drawn in ppt where company mission statement and policies etc… sit on the top, procedures/processes sit in the middle somewhere with work instructions positioned at the very bottom layer. Visual navigation… looks really nice and easy to understand once presented in one image. sorry im day dreaming…my mind deviated for a brief moment.
Other options are Link field
Rich Text field where you can add html code from front end and/or image referenced by file location. That option has limit flexibility unless you like code.
Adding a custom html component to achieve any of the above would be new learning for me. always open to new ideas.
