Lan Xiaomin, Wang Jialin, Wang Shengzhi
The secondary development functional the electric principle graphics libraries is established in AutoCAD. A new method named "invisible boundary" is proposed to draw the electrical graphic symbols. The method has efficiently solved "interruption issue" problem occurred in the middle of reinserting electrical circuit drawing symbols. By utilizing this new type of database, the procedure of discontinuing conducting wire can be avoided, which is beneficial to symbols reediting and also improves drafting efficiency.
