Which of the following document types can be made using non-scaled sketches?

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

Answer: (D)

Non-scaled sketches are useful for capturing relationships and flow in diagram-style documents without needing exact measurements. Arc flash studies benefit from rough sketches to show where equipment sits and how hazard zones relate to one another; the sketch communicates the layout and boundaries, with precise dimensions filled in later as data is gathered. Process flow diagrams are about the sequence of steps and major equipment, not exact scales, so a non-scaled sketch effectively conveys the process and connections. P&IDs focus on piping, valves, and instrumentation connections; they are schematic by nature, so a rough drawing communicates the control loops and process relationships without requiring scale. Because these documents prioritize relationships and logic over precise dimensions, they can all be started from non-scaled sketches and refined into scaled, detailed drawings as the project progresses.
