AI Digital Model Making in Architecture: A Comparative Study of Physical, Digital and AI-Based Methods

Artificial Intelligence is changing the way architects create models by making it easier to automate tasks generate designs and visualize buildings. This research paper looks at how architectural representation has changed from physical models to digital and AI-based modeling systems. The study compares digital and AI-assisted methods based on how efficient they are, how flexible they are, how accurate they are and how well they help with design exploration. The paper examines the role of AI tools like Midjourney, DALL·E, Autodesk Forma and generative design platforms in improving workflows, sustainability analysis and decision-making. It also talks about how AI supports architects by generating concepts optimizing designs and automating repetitive tasks. Through analysis and theoretical understanding the study concludes that AI is a tool that enhances creativity and productivity rather than replacing architects. While AI offers advantages in speed, visualization and performance analysis, human creativity, cultural understanding and design sensitivity remain essential in architecture.
