is a software development platform used by developers to create high-quality Computer-Aided Design (CAD) applications. It is developed by the Open Design Alliance (ODA) , a non-profit consortium that provides tools for working with engineering file formats like .dwg and .dgn .
. It is primarily used by engineers and software developers who need to embed CAD features without building them from scratch. Key Capabilities File Compatibility: Full support for industry-standard formats including DWG, DXF, DGN, and PDF Visualization: Enables high-performance 2D and 3D rendering , including tools for pan, zoom, and orbit. Data Access:
TeighaX 309 is the latest stable release of the ODA’s COM-based CAD engine, bringing modern DWG/DGN format support, faster performance, new API features, and server-friendly stability. If you’re still running an older TeighaX build (below 305), upgrading to 309 is highly recommended for compatibility and capability.
The library introduced improved support for . In the CAD ecosystem, lagging behind on file format support is fatal for a developer. TeighaX 309 ensured that developers could programmatically save files in the latest .dwg formats, ensuring interoperability with the newest versions of AutoCAD used by architects and engineers.
: The ODA has recently transitioned its branding from "Teigha" to "Drawings SDK" or "Drawings X" . If you are looking for the newest version, you should look for the Drawings SDK Getting Started Guide .
