In recent years, 3D Computer-Aided Design (3D CAD) has become an essential tool in design, and the need for digital design has increased. While CAD education is provided in universities and companied, there exists a significant disparity in proficiency levels among individuals. Although studies have been conducted to evaluate learners’ operational skills and proficiency, there has been no detailed analysis of the design process, leaving the specific areas where learners struggle and the underlying causes unclear. To address this issue, this study proposes the Digital Transformation (DX) of CAD education with the aim of enhancing its effectiveness and efficiency. By utilizing computers, we collected command logs from 113 learners and extracted command sequences where errors occurred. Based on the operation content, we performed clustering of command sequences before Undo command to accurately grasp the frequency of errors. For each error, we calculated the variation in occurrence frequency among learners’ command logs and the percentage of errors that were corrected using Undo command. This information can be used to estimate the cause of errors and identify mistakes that require individualized attention.
