# Find a standard structural section

> Ask for a tube, angle or beam in your own words and get real catalogue sizes back, with their standard.

## You need

- The app activated
- Agent connection set to CueCrux Credits or OpenAI Subs (shown beside Send)
- A design conversation open in the Solidworks Agent workspace

## You'll come away with

- Search 306 sections across seven families
- Read the size, wall and source standard for each result
- Know when to narrow a search

## Step by step

1. **Say what you need.** In your design's conversation, describe the section. The Agent turns that into a search by family and designation.
   Try saying: "I need a 50 mm square tube"
2. **Read the results.** Each result lists its designation, the dimensions in their catalogue units and the table it came from, with a fingerprint of that table so you can tell if it changes later.
3. **Narrow it down.** A search returns at most 20 sizes. If it says there were more, add the wall thickness or the full designation.
   Try saying: "a 50 by 50 tube with a 4 mm wall"
4. **Decide for yourself.** Results are catalogue candidates. The Agent does not check that a section suits your loads or matches a drawing you have. That call stays with you.

## Try it

This searches the real bundled catalogue with the same matching rule the app uses. The plain-English requests show how the Agent might phrase each search; you can edit the search yourself. The interactive simulator is on the web page.

- "I need a 50 mm square tube"
- "a 50 by 50 tube with a 4 mm wall"
- "What flat bar do we have 40 wide?"
- "Show me the 100 mm equal angles"
- "Any universal beams around 203 deep?"

## What it won't do

- Candidates only: geometric match and engineering suitability are not checked.
- At most 20 results per search.
- Custom profiles from DXF or DWG are not connected to this search.

## Covers

- Standard section search (Available): Find sizes among 306 standard structural sections in seven families, with their source standard. Where: Solidworks Agent workspace, in a design conversation
