Summary
The CP_CPOD_ATT2OD command in CADPower allows users to transfer block attribute data to CADPower object tables as XDATA, ensuring that attribute information is systematically organized and accessible directly from the drawing entities. This command simplifies data management by linking attribute values to object tables, making information retrieval, reporting, and analysis more efficient. It is fully compatible with leading CAD platforms like BricsCAD, AutoCAD, ZWCAD, and ARES Commander, making it a valuable tool for CAD professionals.
CADPower -> CADPower Object Table Data Tools -> CADPower Object Table Data Tools -> Transfer Attributes to Object Table Data
Key features include:
- Attribute-to-Object Data Transfer:
Transfer attribute values from selected blocks into object table fields, storing the information as XDATA attached to the entities. - Flexible Block Selection:
Choose to transfer attributes from specific blocks or any block within the drawing. - Automatic Attribute-Field Mapping:
Automatically map attribute tags to object table fields when the names match, minimizing manual setup. - Custom Attribute Tag Selection:
Specify individual attribute tags to transfer when only a subset of the data is required. - Two Transfer Modes:
- Block to Block Only: Transfer data exclusively between block entities.
- Block to Any Object: Extend attribute-based data transfer to other object types like lines, polylines, or text objects.
- Interactive Attribute Mapping Interface:
Easily map attributes from the left panel (Attributes) to field names in the right panel (CADPower Object Table fields). - Supports Multiple Attribute Types:
Transfer attributes of String, Real, and Integer data types without compatibility issues. - Cross-Platform Compatibility:
Works seamlessly across BricsCAD, AutoCAD, ZWCAD, and ARES Commander, ensuring reliable operation regardless of the CAD environment.
Practical Applications:
- GIS and Surveying: Transfer geospatial attributes like coordinate values, point IDs, and elevation data to object tables.
- BIM Documentation: Migrate building component attributes into object tables for better information management.
- Mechanical Engineering: Transfer part specifications and material attributes from block annotations to object data tables.
- Utility Mapping: Move manhole IDs, depth values, and inspection statuses from block attributes to object tables for network documentation.
Step-by-Step Workflow:
- Select Source Block:
Choose the block name from which attribute data will be transferred. - Select Target Object Table:
Specify the CADPower object table to populate with the attribute values. - Map Attributes to Fields:
Drag-and-drop or manually map attribute names (left panel) to the target fields (right panel).- Enable “Automatically link similar named Attribute->Fields” if names match.
- Choose Transfer Options:
- Block to Block Only: Restricts transfers between block entities.
- Block to Any Object: Allows transfers to polylines, text objects, and other entity types.
- Filter Attribute Tags (Optional):
- Enable “Transfer specified attributes from ANY block” to include data from multiple block types.
- Enter specific attribute tags to filter the transferred data.
- Execute Transfer:
Click OK to transfer the data from the selected blocks to the object table. - Verify Data Transfer:
Use CP_QUERYDATA or CP_DATAMAN to inspect the transferred object data.
Example Use Case:
A municipal engineer is working on a sewer network drawing where each manhole is represented by a block with attributes like Manhole ID, X/Y Coordinates, Depth, and Status. The engineer uses CP_CPOD_ATT2OD to transfer these attribute values to an object table, enabling easier querying and reporting.
Sample Block Attributes:
| Attribute Tag | Value |
|---|---|
| MANHOLE_ID | MH101 |
| X_COORD | 532100.50 |
| Y_COORD | 184250.75 |
| DEPTH_(M) | 3.5 |
| STATUS | Inspected |
Mapping Configuration:
- MANHOLE_ID → ID
- X_COORD, Y_COORD → Coordinates
- DEPTH_(M) → Depth
- STATUS → Inspection Status
Benefits of Using CP_CPOD_ATT2OD:
- Simplifies Attribute Data Management:
Consolidates scattered attribute data into organized CADPower object tables. - Improves Query and Reporting Efficiency:
Makes it easier to query, analyze, and export object data for external use. - Enhances Drawing Clarity:
Reduces on-screen clutter by storing attribute data within object tables rather than as visible text. - Ensures Data Consistency:
Automated attribute-to-field mapping minimizes human errors. - Saves Time:
Supports batch transfers across multiple blocks or object types.
Troubleshooting Tips:
- Attribute Not Transferring:
- Verify that the attribute tag exists in the block definition.
- Ensure that the target object table is properly defined using CP_DATAMAN.
- Mapping Not Applied Correctly:
- Confirm that attribute names match the field names.
- Use the “Automatically link similar named Attribute->Fields” option to streamline the mapping process.
- Data Not Visible After Transfer:
- Run CP_QUERYDATA to inspect the XDATA attached to the objects.
- Ensure the correct object table was selected during the transfer.
Conclusion:
The CP_CPOD_ATT2OD command in CADPower bridges the gap between block attribute data and object tables, providing a streamlined method for data extraction, organization, and analysis. Whether working on GIS maps, BIM models, or infrastructure drawings, this command ensures that critical data is efficiently transferred and accessible within BricsCAD, AutoCAD, ZWCAD, and ARES Commander.
