Tsinghua drawing auto input and management system, TH-DAIMS 2. 0,is an image-based CAD system, which can be used in drawing renewal and drawing archival management. In TH-DAIMS 2. 0, dynamic memory mapping makes it possible to process the drawings with large size and high DPI. Line picking speeds up the operations of interactive drawing modification and design. Edge smoothing improves drawing quality. Well defined structure of drawing database system is of benefit to its usage and maintenance.Chinese interface is more suitable for local users. And variable system structures can fit the different requirements of users. In the paper, the main functions and characteristics of TH-DAIMS 2. 0 will be outlined, and some new techniques used in TH-DAIMS 2. 0will be described in detail.
