Architectural drawings have played an important role as a means of expressing architectural design; in the early twentieth century, futuristic architectural drawings could be seen from architects such as Richard Rummell and Harvey Wiley Corbett. Subsequently, whether in architectural groups like Archigram or individual architects such as Le Corbusier or Zaha Hadid, the rise of experimental and visionary architectural design led to numerous innovations in drawing techniques. This also elevated the status of architectural drawings as independent works of art. Although after 1990, due to the popularization of CAD and the complexity of architectural projects, architectural firms have gradually become less likely to use architectural drawings to represent their designs, they still have their own unique advantages. To this day, many architectural drawings can still be seen in the graduation works of architecture students, despite the rapid development of digital design. By analyzing architectural drawings from several architects and assessing the impact of societal and technological developments on these changes, this study evaluates the strengths and weaknesses of architectural drawings in conveying visionary architectural designs. Through an analysis of architectural drawings by Japanese architecture students, the research findings indicate that, despite the widespread use of digital design tools, traditional drawing methods continue to play a crucial role in architectural conceptualization and communication. The study concludes by discussing the implications of these findings for future architectural design and representation, emphasizing the ongoing significance of drawing as a tool for architectural innovation and creativity.
