住宅CAD系统中内壁、外壁及垂壁面生成技术

The Technology of Generating the Inner, Outer and Hanging Wall Surfaces in Housing CAD Systems

介绍住宅ＣＡＤ系统中房屋的内部墙壁面、外部墙壁面以及垂壁墙壁面的生成技术。并讨论内部及外部墙壁面与门、窗位置的关系，较好地解决了内部墙壁与外部墙壁之间门、窗端点位置的统一性问题。另外还着重讨论了圆拱形垂壁的面生成技术。

The technology of generating the Inner, Outer and Hanging Wall Surfaces in a Housing CAD System is presented in this paper. The relations between the positions of the inner wall and outer wall surfaces, between doors and windows and, between the wall surface and doors and windows are discussed. The method to keep consistency of a house structure according to the positions mentioned is also presented. In addition, the technology of generating arch hanging wall surfaces is disussed in detail.
