Convert LOB to DXF

Understanding the LOB and DXF file formats

LOB files are typically associated with Surpac, a popular geological modeling and mine planning software. LOB files store 3D wireframe or block model data used in mining and geological applications. These files are proprietary and not widely supported outside specialized mining software.

DXF (Drawing Exchange Format) is a CAD file format developed by Autodesk. It is widely used for exchanging 2D and 3D drawings between different CAD programs. DXF files are text-based and compatible with many design, engineering, and GIS applications.

Why convert LOB to DXF?

Converting a LOB file to DXF format allows you to use geological or mining model data in general-purpose CAD software such as AutoCAD, DraftSight, or QGIS. This is useful for sharing, editing, or further processing your models outside the original mining software environment.

How to convert LOB to DXF

Since LOB is a proprietary format, the best way to convert LOB to DXF is by using Surpac itself. Surpac provides built-in export options to save wireframe or block model data as DXF files.

• Open your LOB file in Surpac.
• Navigate to File → Export → DXF or use the export function from the wireframe/block model menu.
• Choose the objects or layers you want to export.
• Set the export options (such as units, layers, and entities).
• Save the exported file with a .dxf extension.

If you do not have access to Surpac, you may need to request the conversion from someone who does, as there are no third-party converters that support LOB files directly.

Recommended software for LOB to DXF conversion

• Surpac (by Dassault Systèmes): The industry standard for working with LOB files and exporting to DXF.

For viewing or editing the resulting DXF files, you can use:

• AutoCAD
• DraftSight
• LibreCAD
• QGIS (for GIS applications)

Summary

To convert LOB files to DXF, use Surpac's export functionality. This enables you to utilize your mining or geological data in a wide range of CAD and GIS applications.
