ＴＨＦＴ３Ｄ是在ＡｕｔｏＣＡＤＤｅｓｉｇｎｅｒ参数化三维造型软件基础上开发的三维铸造工艺ＣＡＤ系统。它以微型计算机为运行环境，能够在三维零件图上直接进行铸造工艺设计，快速生成三维铸造工艺图并输出包括立体轴测图在内的工艺图样。系统提供参数提取、数据库管理、三维参数化图库以及其它辅助工具。整个设计过程直观方便，设计效率和质量明显提高。
THFT3D is based on AutoCADDesigner parametric three-dimensional modeling software developed based on the three-dimensional casting process CAD system. It uses the microcomputer as the operating environment, the casting process design can be directly on the three-dimensional parts drawings, rapid generation of three-dimensional casting process diagram and output, including the three-dimensional axial mapping process drawings. The system provides parameter extraction, database management, three-dimensional parametric galleries and other aids. Intuitive and convenient throughout the design process, design efficiency and quality improved significantly.
