What are plane labeling and traditional labeling? Is paper usually marked by plane method or traditional method in actual construction site?

In the rebar drawing, traditional labels were used before. For example, a cross-sectional view of a beam is given, which indicates the position of reinforcement. Different parts of steel bars on the beam indicate the number of steel bars in different positions.

Now, they are all labeled by plane method, and there is no cross-sectional view, only centralized labeling and in-situ labeling. See the steel bar atlas for details, such as 03G 10 1- 1.
