What are the two methods of presentation used for column plan construction drawings?

1, the list of writing: the specific parameters of each column (including the number, section size, reinforcement, etc.) one by one labeled in the column table, to draw the form of level construction drawings. Through the list of annotations, the detailed information of each column can be clearly listed, providing easy to find and compare the data.

2, cross-section writing: this way directly in the column layout plan, the specific size of each column and reinforcement labeling. When using this method, add text or symbols in the corresponding position to indicate each parameter, such as section size and the number of reinforcement. This can be done to visualize the materials required for each column and their specifications at different locations.
