Which of the following best describes non-scaled sketches in Bluebeam?

• A. Arc Flash Studies
• B. Process Flow Diagrams
• C. P&IDs
• D. All of the above

Answer: (D)

Non-scaled sketches are markups that aren’t bound to a specific measurement scale, so you can convey layout, flow, or concepts quickly without committing to exact dimensions. Arc Flash Studies, Process Flow Diagrams, and P&IDs are all commonly treated this way because they focus on relationships, sequences, and safety logic rather than precise geometry. You can annotate, add notes, and discuss the diagram without worrying about scale, and if precise measurements are needed later, you can calibrate the document to a scale and use measurement tools accordingly.
