SCENARIO 02·R&D·Drawing recognition

Manually Identifying Dozens of Balloons on Each Engineering Drawing

An engineering drawing may contain 50 or 60 balloons, which are numbered circles on the drawing. The person reading the drawing must find and identify each one before the next process can begin.

This task requires little judgment but sustained attention. More balloons take more time and increase the risk of omissions. One laptop bearing manufacturer advised by us began implementation in the first half of 2026 and deployed about 50 AI Agent within six months. Engineering drawing review was one of the applications.

At a glance

How it was done

  1. Open the drawing and find every balloon
  2. Identify each number and annotation
  3. Create the balloon list
  4. Check everything again from the beginning

Where it gets stuck

A drawing may contain 50 or 60 balloons. When people check them one by one, more balloons increase the risk of omissions. Duplicate or missing numbers are also hard to spot at a glance.

With an AI Agent

  1. Open the drawing and find every balloon
  2. Identify each number and annotation
  3. Create the balloon list
  4. Check everything again from the beginningHuman approval

The AI Agent finds balloons, identifies their annotations, and prepares the list. Personnel only review the list and the drawing issues it identifies before sending the results to the next process.

In EX-BRK-0927, balloon 7 appears twice: once at R5 and once at 25±0.05 in the side view. I also cannot find 9 in the list. Please confirm which one needs to be changed.

Drafting, Mr. Chang
I will open the drawing this afternoon and get back to you.

I just checked everything again from the beginning. There is also a balloon 11 in the lower-right corner of the side view. It has no leader, so I cannot tell which dimension it refers to.
09/28 14:05
Drafting, Mr. Chang
Understood. I will fix all three and send you the updated version.
09/28 16:30
Illustration only. This drawing has only 12 balloons, but number 7 appears twice and number 9 is missing from the list. Actual drawings often have 50 or 60 balloons, so these issues can only be found by checking them one by one. In the messages on the right, two checks were needed to find all the reported issues. The side view also has a hole depth of 15 but no balloon, and this issue was never mentioned in the messages.

With an AI Agent

  1. 01
    What it doesFind every balloon on the drawing
    Standard appliedFind every numbered circle on the drawing, then follow its leader to the dimension or annotation it identifies
    OutputEach balloon and the location it identifies
  2. 02
    What it doesIdentify the annotation
    Standard appliedCopy each annotation exactly as shown on the drawing. Do not omit any tolerances or symbols, such as Ø40 H7 or 25±0.05. Write "Cannot determine" when the target is unclear, and flag unclear text for personnel to confirm.
    OutputBalloon list: number, annotation, view, and notes
  3. 03
    What it doesCheck the drawing for issues
    Standard appliedCheck for duplicate or skipped numbers, balloons without leaders, and dimensions or notes without balloons. List only the issues. Do not renumber balloons or fill in missing content.
    OutputDrawing issue list identifying the relevant number or dimension for each issue
  4. 04
    What it doesSend the results for manual review
    Standard appliedState the total number of balloons and issues at the end of the list so personnel can check for omissions
    OutputThe list goes to the next process only after manual review. Personnel and drafting staff decide whether to revise the drawing.

TimeServes about 20 user sessions per week and saves about 67 hours in total

Human approval
Step 4 remains a manual review because 99% does not mean every drawing can pass automatically. Personnel must review the results before the process continues.

This case is useful because it does not give one general accuracy rate. It defines the AI Agent's limits by balloon count. Users know which drawings require closer attention, making the manual review more focused.

01Upload the Drawing and Instructions

EgentWrX conversation screen: An employee uploads the Example Bearing Housing part drawing. The instructions say to copy each balloon exactly as shown, organize the results in a table, and separately list the drawing issues and totals.
  1. 1Upload the Example Bearing Housing part drawing.
  2. 2The instructions say to copy the drawing exactly, organize the results in a table, and separately list the drawing issues and totals.

02Processing

EgentWrX processing screen: After reading the part drawing, the AI Agent begins preparing the balloon list. The first rows copy Ø40 H7 and 4-Ø9 through holes exactly as shown.
  1. 1The AI Agent first reads the uploaded part drawing.
  2. 2After reading it, the AI Agent begins preparing the balloon list.
  3. 3Annotations are copied exactly as shown. All tolerances and symbols in Ø40 H7 and 4-Ø9 through holes are retained.

03Balloon List and Drawing Issues

EgentWrX results screen: The second half of the balloon list and the drawing issue list show duplicate number 7, missing number 9, balloon 11 without a leader, and dimension 15 without a balloon. Totals appear at the end.
  1. 1Balloon 11 has no leader. The result says "Cannot determine" instead of guessing the content.
  2. 2The drawing issue list identifies duplicate and skipped numbers, missing leaders, and dimensions without balloons.
  3. 3The totals at the end show 12 balloons and 5 issues, helping personnel check for omissions.

FAQ

How accurate is the drawing-reading AI Agent?
Accuracy is 100% for drawings with 50 to 60 balloons and 99% for drawings with more than 60. These results were calculated by balloon count at a laptop bearing manufacturer advised by us. The figures come from a 2026 media report about this client. The report did not provide accuracy for fewer than 50 balloons.
Does 99% accuracy eliminate the need for manual review?
No. In this case, balloon count is used to estimate the capability limits, and personnel still review the results. A 99% accuracy rate does not mean every drawing can pass automatically. Manual review can also focus on drawings with more balloons.
Can engineering drawings remain inside the company?
Yes. EgentWrX supports cloud, on-premises, and hybrid cloud and on-premises deployment architectures. With on-premises or hybrid deployment, drawing data can remain inside the company. The company's data policy determines where it is stored.
