摘　　要：在AutoCAD环境中,通过对其二次开发,设计并实现了房屋采暖专业软件系统.通过对用户的需求进行分析,提出系统的功能模型,并对其功能需求作出模块划分,进行软件的系统设计.解决了自动计算面积、图元实体与相关属性绑定和自动布置输水管等关键问题.所开发的系统更有层次性,图形区域面积计算更准确,实现参数化绘图,并可方便地在房间内对水管线进行自动布局.A building heating software system is designed and developed based on AutoCAD.By analyzing custom＇s requirements,a functional model of the system and its module partition are advanced.And then,its system design is accomplished.Meanwhile,some key problems,such as automatic area computation,the colligation of primitive entity and its attributes,and automatic layout of water pipes are solved.It is shown that the system architecture is more reasonable,the graphic area computation is more accurate,the parametric drafting is achieved,and water pipes can be laid out automatically in a room.
