The key factor of BIM implementation is the standardization and automation framework of construction drawing. For pragmatic reasons, the framework should not only support basic finite element analysis, drawing and estimation software but also different versions of AutoCAD. Technically speaking, automation, individuation, interaction and platform adaptability of the framework are the keys. Automation means high drawing speed and better drawing quality; individuation means the construction drawing framework is adaptable to different ways of drawing expression; platform adaptability means the framework is compatible for other drawing software; interaction means related drawings can modify themselves when a structure component is modified. In the end of the article, the process of implementation of standardization and automation framework is introduced.
