Welcome Carl, good to see a technical illustrator on the board.
I don’t know if I have an immediate fix, but my first thought is that this is an overall workflow issue.
What changes will you need to make to the Illustrator objects in Photoshop?
Have you tried pasting your AI objects into PS as Smart Objects?
I imagine these as being walls, doors, furniture, etc?
My most extreme process for moving vectors into PS, when I need a shape layer for every vector layer of a complex component, is to create a transparent box around the component in AI as a registration box.
Than I copy the registration box and one of the object layers, and paste into a new PS file, than delete the bounding box.
Than I repeat the process with all of the AI layer objects until the component is recreated, perfectly registered, as individual shape layers in PS.
