Thank you @jeff prince and @Art V. I am learning to understand Vectorworks a bit. Unfortunatly who made the design is no longer willing to cooperate which is why i am trying to get the information out of this model (if you would be concerned: He was properly contracted and payed for his work, but had a fallout with the rest of the team so i cannot go to him with these questions/to provide me with dimensions of his plan).
I can do without most of the furniture, desks/chairs/screens/stools/lamps i can redraw in cad. In the screenshot provided by jeff i tried to highligt/identify what elements i preferably have in cad, because with that i can reproduce this plan and develop it for execution. 2d would be sufficient for me, and i could do without most of the furniture. I can rebuild the plan in autocad if i have the floorplan with the new walls, and in either 3d or 2d the view of the existing core where he designed with wooden slats an red printed/LED design.
Thank you for your time invested already!
