It is true that the widely using of plane-method construction drawing has largely improved the productivity of construction industry. With BIM maturing and expanding in china, 3D design and visualization have been the inevitable trend. The new technology based on BIM has changed the traditional design model. The dependence between mark symbols and dates in the plane method disagree with building's representation and collative design. To make it more suitable to the BIM's development, an improvement called informatization which link the information represented by mark symbols with graphic entities and embed them into BIM model needs to be introduced into current plane method. To achieve this goal, the China BIM Standards also should be modified.
