# Try the sample drawings

> A small steel frame with two deliberate discrepancies you can see for yourself.

## Download the two PDFs

> [card] [Design reference](https://sonjciatrarbzpqojwrf.supabase.co/storage/v1/object/public/trace-demo/design-reference.pdf)
>
> One page showing the engineer's specified beam and connection.

> [card] [Submitted shop drawing](https://sonjciatrarbzpqojwrf.supabase.co/storage/v1/object/public/trace-demo/submitted-shop-drawing.pdf)
>
> One page with a changed beam size and fewer connection bolts.

These are fictional training drawings. They must not be used for design, fabrication, or construction.

## What to look for

| Item | Design reference | Submitted drawing |
| - | - | - |
| Beam **B07** | **W21x44** | **W18x35** |
| Connection **C-04** | **6 bolts** | **4 bolts** |

**B07** is a member identifier. **W21x44** and **W18x35** identify different wide-flange steel sections. **C-04** identifies the connection detail. You do not need to perform a structural calculation to see that the callouts differ.

## Run the comparison

1. Upload the first PDF as **Structural drawings**.
2. Upload the second PDF as **Shop drawings / submittal**.
3. Choose **New review** and name it **My first demo review**.
4. Select those two documents and choose **AI document review**.
5. Start the review and inspect the results.

![Design and submitted drawing displayed side by side in Trace](https://mintcdn.com/trace-review/upnSgffsClGaLTzy/images/compare-drawings.png?fit=max\&auto=format\&n=upnSgffsClGaLTzy\&q=85\&s=1d33ac835d5ccb4f7d18f96ef1371c42)

Compare the reference and submission, then inspect the written evidence for each finding.

## The result from our live test

Trace returned two findings: the B07 section mismatch and four bolts in C-04 where the reference specifies six. Both findings cite page 1 of the corresponding documents.

AI output can vary between runs. Finding titles and order may differ. This simple test demonstrates the upload and review workflow; it does not establish accuracy on real engineering drawing sets.

You can upload the downloadable sample PDFs into your own project to explore the review workflow. The sample drawings are fictional.
