DWG Format (DWG)

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.
