The Macros dialog box allows you to run, edit, delete, and create macros as well as set the VBA project options.
Open the Macros dialog box from the ribbon in AutoCAD by clicking Manage tab 
Applications panel Run VBA Macro, or issue VBARUN at the AutoCAD Command prompt.
The names of all macros in the valid range are displayed in this dialog box. You can change the valid range by using the Macros In drop-down list. This list specifies the projects or drawings whose macros are displayed. You can choose to display the macros in
- All drawings and projects
- All drawings
- All projects
- Any individual drawing currently open in AutoCAD
- Any individual project currently loaded in AutoCAD
By limiting the valid range you can control how many macro names appear in the list. This will help you in the cases when many macros are available in the loaded drawings and projects.
