.a2t — AutoCAD Text File
Autodesk · 1982
An .a2t file is a plain text file format used by AutoCAD to store and manage textual data within CAD drawings.
Key Features
- Plain text format, easily readable and editable with standard text editors.
- Stores textual annotations and elements specific to AutoCAD drawings.
- Facilitates the export and import of text data from CAD projects.
- Can contain various types of text-based CAD information.
Best For
- Storing and transferring text elements for AutoCAD.
- Simple export/import of textual annotations.
- Reviewing CAD text content outside of AutoCAD.
- Automating text creation in AutoCAD drawings.
Less Ideal For
- Storing complex graphical data.
- Sharing entire drawings with full graphical fidelity.
- As a primary format for non-textual CAD elements.
- General document creation outside of CAD contexts.
Common Use Cases
- Exporting text labels and dimensions from an AutoCAD drawing.
- Importing pre-formatted text into an AutoCAD drawing.
- Archiving textual annotations from CAD projects separately.
- Programmatic generation or modification of text within CAD files.
How to Open It
- Open AutoCAD and use the 'Import' or 'Insert' commands, selecting the .a2t file.
- Open the .a2t file in any standard text editor (like Notepad, VS Code, Sublime Text) to view its raw content.
- Use specific commands within AutoCAD to place or manage the text data from the .a2t file.
What is a .a2t file?
An .a2t file is a plain text file primarily used by AutoCAD to store specific text elements and annotations within a drawing. These files can contain information such as line text, multiline text, dimensions, and other textual data that are part of a CAD project. While it's a text-based format, it's structured in a way that AutoCAD can easily parse and integrate its content into drawings. This makes it useful for exporting or importing text data, allowing for easier manipulation or archiving of textual information associated with CAD designs.

Common Problems with .a2t Files
Frequently Asked Questions
Yes, you can import the .a2t file into AutoCAD and edit the text objects as you would with any other text within the drawing.
No, .a2t is strictly a text-based format and does not contain graphical data; it only stores textual annotations.
While it's a plain text file, other CAD software may not recognize its specific structure. It's primarily intended for use with Autodesk products.
Technical Details
The .a2t format is essentially a plain text (ASCII) file, meaning its contents can be read and edited with any standard text editor. However, it adheres to a specific structure or syntax that AutoCAD recognizes for its text objects. This allows AutoCAD to interpret the data and place it correctly within a drawing environment, such as handling formatting and positioning.
