Abstract: In the Port Engineering, there are a large number of standardized components. Parameterization and programming of the drawing of all these standardized components can not only reduce the large amount of monotonous repetitive work, but also greatly enhance the efficiency and quality of engineering drawing. The powerful VBA embedded in AutoCAD has been used to develop an Automatic Mapping System with friendly user interface for Parameterized Pile Cap. The system integrates parametric design and drawing management, and thereby significantly improves the drawing quality and efficiency in the process of pile cap design.

Key words: computer application, automatic mapping system, parametric design, pile cap
