摘要
In the technical drafting standards, some standards of chart line classification are uneasy to understand and some specifications of chart line descriptive are inconvenient for drafting. The article analyses the problems above and puts forward the related schemes. In the light of the standardization and simplification of the dimension elements and height mark symbols to be formulated, the article gives some suggestions.
