Why are engineers writing paragraphs to get a simple table from ChatGPT? There’s a faster, clearer way—and it starts with talking like a human.
What’s Good About It
Here’s what makes conversational prompting surprisingly effective for building engineering calculation templates:
Cleaner Input Extraction
You can simply say: “List the input variables from this section, with symbol, value, units, and source.” GPT handles the structure without extra effort.
Fast Turnaround for Templates
Within 2–3 follow-ups, you can turn raw client data or textbook examples into reusable templates—ideal for pumps, line sizing, vessel calcs, and more.
Adaptable for Real Workflows
Instead of rebuilding prompts from scratch, you iterate naturally:“Now turn this into a blank template.”“Add a column for citation format (Ref #, pg #).”“Add formulas where possible.”
What’s Bad About It
Conversational prompting only works if you're precise in plain terms. Here’s where engineers go wrong:
Vague inputs like “add sourcing best practices” get vague output
If you skip unit format or citation formatting, GPT will too
Doesn’t work well for automation unless you lock the format after testing
Why It Works for Engineers
Let’s say you’re sizing a centrifugal pump.
Instead of building a GPT from scratch, try this:
“Extract all input variables from this datasheet and organize in a table.”
“Add formula column and source citation (Ref #, pg #).”
“Now turn this into a blank template I can reuse.”
Within one conversation, you’ve got a standard calc template—and no need to restart or over-prompt.
Conclusion / Call to Action:Stop writing long, rigid prompts. If you can talk like an engineer giving clear steps to an intern, you can build reusable templates with ChatGPT—fast.
