Summary

The GT_DATAMAN command is a data management tool within BricsCAD, AutoCAD, ZWCAD and ARES Commander, designed to define, store, and manage object-related metadata using Extended Entity Data (XDATA) within a CAD drawing. This feature enables users to create a database structure within CAD files, ensuring metadata is linked directly to drawing objects.

Key Features Include:

1. Object Table Management

• Allows creation, selection, and deletion of object data tables.
• Uses an INI-based system to define database structures.
• Stores metadata within XDATA, eliminating the need for external databases.

2. Field Management

• Enables users to add, edit, remove, or reorder fields within an object data table.
• Supports various data types such as:
  • String (Text-based information)
  • Real (Floating point numerical values)
  • Integer (Whole numbers)
  • Link (File reference linking CAD objects to external files)

3. Data Storage & Accessibility

• All data is stored in XDATA, ensuring it remains within the drawing file.
• The GT_DATAMAN INI file defines the database structure, making it portable and easily configurable.
• Objects with associated XDATA can be queried, exported, or linked to external files.

4. Linking External Files

• Supports associating CAD objects with external files such as images, PDFs, reports, and spreadsheets.
• Provides browse and show options, allowing users to open linked files directly from within CAD.

5. Customization & Flexibility

• Users can define their own database schema tailored to project-specific needs.
• Provides predefined dropdown values for easy data entry.
• Allows multiple object data tables to be defined and managed within a single drawing.

Benefits

• Eliminates the need for external databases by keeping all object-related metadata within the drawing file.
• Improves data management in GIS, infrastructure, and facility management projects.
• Enables better organization of CAD data, making it easier to search, filter, and analyze.
• Enhances interoperability, allowing CAD professionals to integrate non-graphical data with drawing objects.
• Boosts efficiency by reducing manual data input errors and providing structured data fields.

The GT_DATAMAN command is an essential tool for surveyors, engineers, GIS analysts, and CAD managers, ensuring seamless metadata integration within CAD drawings while maintaining data integrity and accessibility.
