# AS Batch Attribute Editor (AutoLISP)

This tool lets you select an area in your drawing, list **unique block names starting with `AS*`**, list **unique attribute tags** for a chosen block, and then **change one attribute value for all matching blocks** inside the selected area.

## Files
- `AS_AttrBatch.lsp` — AutoLISP logic (**this is the only required file**)
No `.dcl` file is used — this is a command-line tool.

## Install / Run
1. Copy `AS_AttrBatch.lsp` into any folder.
2. In AutoCAD run `APPLOAD` and load `AS_AttrBatch.lsp`.
3. Run command: `ASBATCHATTR`

## How to use
1. Select a zone/part of the drawing (window/crossing selection is fine), then press **Enter**.
2. Choose the block:
   - Option **Pick**: click a block in the selected zone
   - Option **List**: choose from a numbered list
   - The list shows **unique block names** with a **count** like `AS_VFD (50)`
3. Choose the attribute tag from the **numbered list**.
4. Type the new value and press **Enter**.

Only the chosen attribute tag is updated. All other attributes remain unchanged.
