# Scan to Pipe - Standards

![CmdSettings.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/CmdSettings.svg)

[Scan to Pipe catalogs](/v1/docs/cyclone-3dr-scan-to-pipe-catalogs) are composed of standards. This page allows to import and view standards.

- Use **Add new Standard** to load a custom standard from disk.
- The first list displays all available standards
- The second list displays all references included in the selected standard

> [!WARNING]
> ### Notes
> 
> - Cyclone 3DR Standards are stored in C:\Users\Public\Leica Geosystems\Cyclone 3DR\ScanToPipe\Standards.
> - Standards can be imported from CSV or TXT files.

> [!WARNING]
> ### Standards format
> 
> All standards files require a four lines header:
> 
> 1. CODE: the name of the standard which will be displayed in Cyclone 3DR.
> 2. UNIT: the unit of the standard, either inches (in) or millimeters (mm).
> 3. Object type: which component type is this standard for.
> 4. Required dimensional characteristics: values that define the elements
