|Dr. Sun Yat-Sen’s Memorial Hall Building|
NEEDS AND GOALS
The Dr Sun Yat-Sen’sMemorial Hall is located in Guangzhou, China. It was built in 1929 in honour of Mr Sun Yat-Sen(the forerunner of the great democratic revolution in China) and designed by the famous architect Lu Yanzhi (1894-1929). The building has an octagonal structure and it is a combination of the Chinese traditional palace style and the Western modern space and structure design method. The two goals of the project were:
1. To conduct a comprehensive digital survey and acquisition of the 3D information of the historical building.
2. To create a fine 3D file with all the information of the preservation status of structure, decoration and equipment. This huge building was used for many years and is full of precarious equipment, structures, and decorative components, which caused lots of difficulties both for laser scanning activities and point cloud postprocessing.

The Gexcel software allowed to extract from the point cloud the building’s plans, elevations and sections, necessary to generate the CAD drawings in a 1:100 scale. With a highly collaborative group and AutoCAD®integration, a final 3D database of the Dr Sun Yat-Sen’s Memorial Hall was established for follow-up research, displaying and promotional activities. The work was successfully completed in 2 weeks.
