This article introduces the evolution of application software used during the architectural design phase, aiming to help BIM professionals understand the development process of design software. I hope this overview proves useful to everyone.
1. Two-Dimensional Graphics (Manual Drawing):
Originally, drawings were created manually on paper using only hands and rulers. This two-dimensional graphical method, based on Descartes’ projection geometry, has been employed for thousands of years, particularly in ancient cartography. Even today, manual sketches remain useful, especially during the early stages of architectural concept design to visually express initial ideas.
2. 2D Graphics (Computer-Aided Drafting):
Since the 1980s, with the rise of personal computers, traditional CAD tools have allowed architects to generate 2D graphic files digitally. Two-dimensional drawings continue to be the primary medium throughout the construction industry, serving as the standard for architectural graphics from design to construction and maintenance management. While CAD has been described as a revolutionary tool in construction, its impact is mostly limited to replacing manual drawing tools with computer peripherals like mice and keyboards. The fundamental design methods and the nature of 2D graphics have remained largely unchanged. In reality, CAD is better described as computer-aided drafting rather than true computer-aided design.
3. 3D Modeling:
In recent years, advances in software and hardware have made 3D modeling an increasingly popular approach in architectural design. Software such as SketchUp, 3ds Max, Rhino, and others enable the creation of detailed 3D models. Sometimes referred to as BIM modeling software, this next generation of CAD uses a single 3D model as a unified representation throughout conceptual design, detailed design, and even construction documentation stages. This approach significantly reduces inconsistencies caused by fragmented 2D data and improves the efficiency and quality of design execution.
4. 3D Information Modeling (BIM):
3D Information Modeling takes 3D modeling further by embedding and extracting detailed building information within the model. Tools like Revit, ArchiCAD, MicroStation, and Vectorworks are examples of BIM modeling software. They use intelligent objects and templates to create 3D models enriched with inherent information. The core of BIM is information management—without detailed building data or its application in later design stages, a 3D model alone cannot be considered true BIM. BIM integrates various previously scattered building data into a single, stage-based model that coordinates multiple disciplines. This integration greatly enhances the efficiency of every phase of a construction project.
That concludes the overview of application software evolution during the design phase. I hope this article has provided you with a clearer understanding of how architectural design software has developed over time.
