Convert CIT to DGN

Understanding CIT and DGN file formats

CIT files are raster image files commonly used for storing scanned drawings, especially in engineering and mapping applications. They are often monochrome and are typically used as background references in CAD systems.

DGN files are vector-based drawing files created by Bentley Systems' MicroStation and other CAD software. DGN is widely used in civil engineering, construction, and infrastructure projects for storing precise design data.

Why convert CIT to DGN?

Converting a CIT raster image to a DGN vector format allows you to integrate scanned drawings into CAD workflows, enabling editing, scaling, and precise measurements. This is essential for updating legacy documents or incorporating old plans into modern design projects.

How to convert CIT to DGN

Since CIT is a raster format and DGN is a vector format, the conversion process involves raster-to-vector conversion. This process is also known as vectorization. Specialized software is required to accurately trace and convert raster images into editable vector elements.

Recommended software for CIT to DGN conversion

• Bentley Descartes: This is Bentley's official raster editing and vectorization tool. It integrates seamlessly with MicroStation and supports CIT to DGN conversion. Use File → Import Raster to bring in the CIT file, then use the vectorization tools to convert and save as DGN.
• AutoCAD Raster Design: This Autodesk add-on allows you to insert CIT files, use vectorization tools, and then export the result as a DGN file via Export options.
• Scan2CAD: A dedicated raster-to-vector conversion tool that supports CIT input and DGN output. Open the CIT file, use the vectorization feature, and then File → Export → DGN.

Step-by-step conversion process

1. Open your chosen software (e.g., Bentley Descartes or Scan2CAD).
2. Import the CIT file using the File → Import menu.
3. Use the vectorization or tracing tools to convert the raster image to vector elements.
4. Edit and clean up the vector data as needed for accuracy.
5. Save or export the file as a DGN file using File → Save As or File → Export → DGN.

Tips for best results

• Ensure your CIT file is high quality and clear for better vectorization accuracy.
• Manually review and edit the vectorized output to correct any errors or misinterpretations.
• Use layer management to organize different elements during the conversion.
