DWG is a binary file format used by AutoDesk AutoCAD. It can contain 2D or 3D objects and offers compression and a CRC check for internal data.
LEADTOOLS supports DWG 12, 13, 14, 15 (DWG2000), and 18 (DWG2004) files.
This file format supports loading with different units and viewing multi-degree spline.
This file format is not supported in the Imaging Pro toolkits. Read support for this format is provided in the Document and Medical Imaging toolkits.
The default extension used by this format is: DWG.
LEADTOOLS supports loading this format as a raster image, vector image, or SVG (Scalable Vector Graphics) document.
