Flat Designs Won’t Cut It: Why 2D Needs a Third Dimension in Today’s Collaborative Architecture

From inked drawings on tracing paper, to highly detailed digital 3D models, the role of the architect has evolved, and next-gen design software is empowering today’s architects with valuable data and design flexibility. In the past, the work was meticulous and required great manual effort, with every line and detail drawn by hand using rulers and other tools. Over time, programs like Revit revolutionized the field by enabling the creation of precise and digitally organized drawings, simplifying edits and the replication of components.

Architects still faced significant inefficiencies, particularly when making a single change that required updates across multiple drawings. For example, adjusting the height of a step by just 1 centimeter would mean modifying numerous lines, hatchings, and details across all relevant sections, elevations, and floor plans. This process was not only time-consuming but also increased the risk of errors, complicating workflows and project coordination. Although the shift from paper to digital drafting offered advantages, it retained many of the limitations of two-dimensional representation. Projects continued to rely heavily on flat views, with full spatial understanding often requiring a level of interpretation that was challenging for clients and stakeholders to grasp.

BIM and Beyond: How 3D Tools Are Transforming Architectural Practice

With the arrival of 3D modeling tools and, more recently, Building Information Modeling (BIM), the design practice gained a new dimension—literally. It became possible not only to visualize space in a more realistic and complete way but also to integrate crucial information about materials, costs, and performance directly into the model, transforming both the creative process and construction management. In fact, BIM software has transformed the design landscape by addressing many of these limitations. By creating a comprehensive 3D model that automatically generates both 2D and 3D drawings, BIM simplified workflows, reduced errors, and made design changes instant across all views. It also integrated valuable project data, such as material costs and performance, directly into the design, offering a more holistic approach to architecture.

It’s important to point out that 2D and 3D are not competitors but rather allies in the design process. 2D stands out for its simplicity and speed, making it ideal for initial sketches of floor plans and structures, as well as facilitating the production and sharing of ideas between professionals and clients. As projects gain complexity, with intricate facades and irregular shapes, 3D offers the necessary precision and clarity, providing a more detailed and realistic spatial view. Together, they create an integrated approach that optimizes communication, accelerates iterations, and ensures more informed decisions throughout the project’s development.
