Convert DWG to MDB

Understanding dwg and mdb file formats

DWG is a proprietary binary file format used for storing two and three-dimensional design data and metadata. It is the native format for several CAD packages including AutoCAD. MDB stands for Microsoft Database and is the default file format for Microsoft Access databases, storing structured data in tables, queries, forms, and reports.

Purpose of converting dwg to mdb

Converting a DWG file to an MDB file is not a direct conversion of graphics to database, but rather an extraction of attribute data (such as block attributes or object data) from CAD drawings into a structured database format for further analysis, reporting, or integration with other systems.

How to convert dwg to mdb

There is no one-click solution to convert a DWG drawing directly into an MDB database. The process typically involves exporting attribute or object data from the DWG file and then importing it into an MDB file. Here’s a common workflow:

1. Open your DWG file in AutoCAD or a compatible CAD application.
2. Use the Data Extraction tool (found under Insert → Linking & Extraction → Extract Data in AutoCAD).
3. Follow the wizard to select the objects and attributes you want to export.
4. Export the extracted data to a CSV or Excel file.
5. Open Microsoft Access and create a new database (MDB file).
6. Use External Data → Import → Text File to import the CSV or Excel file into your MDB database.

Best software for dwg to mdb conversion

• AutoCAD: For extracting data from DWG files using the Data Extraction wizard.
• Microsoft Access: For importing the extracted data into an MDB database.
• FME Desktop: A powerful data conversion tool that can automate the process of extracting CAD data and writing it directly to an MDB file.

Tips for successful conversion

• Ensure your DWG file contains well-structured attribute data for meaningful database import.
• Review the exported CSV or Excel file for accuracy before importing into Access.
• Consider using FME Desktop for large-scale or automated conversions.
