In the research institute's scientific design work, designers need to perform the task of statistical analysis for PDF drawings, including determining the dimension and number of pages of the PDF drawings, as well as calculating the equivalent amount of A4 pages. This process is tedious, time-consuming, and error prone. To solve this problem, this paper proposes the design and implementation of an automated PDF drawing statistical tool based on Python. The tool interacts with designers through a Graphical User Interface (GUI), enabling fast and accurate statistical analysis of all PDF drawings within a selected path. This significantly improves efficiency, reduces workload, and eliminates human errors.
