BIM and CAD are popular terms among architecture professionals. Since the emergence of Computer-Aided Design (CAD) during the 1980s, the field of architecture has experienced a transformation in its truest sense. The challenges of hand drafting no longer exist, as computerized versions of designs are readily available to architects.
Similarly, Building Information Modeling (BIM) is another revolution in the making, as it is a process with the potential to automate the entire workflow and save precious time. But, many people seem to be confused between BIM and CAD, and their differences. In this post, we will check out the nuanced distinctions between the two phenomena and see how they can help those in the construction business.
What is CAD?
The term CAD is the acronym for Computer-Aided Design. CAD is a software that facilitates design and documentation via computer technology. Thus, CAD software programs are used as drafting tools to lay out projects. They enable drawings and blueprints to be created digitally – usually in 2D representations.
What is BIM?
The term BIM is the acronym for Building Information Modelling. It refers to a set of software tools that make it possible to visualize design ideation with realistic dimensions from a range of angles. With BIM, the design and architecture team of a project can enjoy the virtual experience of a construction project, such as a road, bridge, monument, etc. When compared with CAD, BIM is a rather new phenomenon, but its adoption has massive advantages. The right BIM consulting firm can offer multiple benefits like conflict prevention, error reduction, improved piping plans, etc.
BIM v/s CAD
As we have already highlighted, BIM and CAD are different. BIM is a tried-and-tested mechanism and refers to the process of using computers for designing a building. CAD helps in creating high-quality drawings and eliminating the manual cumbers of conventional hand drafting. On the other hand, BIM is a new fellow on the block, which helps create and manage information on a construction project across its lifecycle. In other words, BIM leverages CAD concepts to design buildings in a way that includes both the physical and intrinsic characteristics of the building.
Similarly, another difference revolves around the use of CAD and BIM. The former has been traditionally used in the construction industry for two-dimensional or 2D designs. On the other hand, BIM is fast-replacing CAD by helping architects, contractors and engineers work together throughout a construction project and get real-time visualization and model analysis. Therefore, a BIM consulting firm is worth considering in 2023!
BIM vs CAD – Software Analysis
The software between BIM and CAD is quite distinct. To begin with, the software used in CAD – AutoCAD- has a steep learning curve, which means it takes a longer time to master the software program. On the other hand, the software used in BIM – ArchiCAD – has a smaller learning curve, and one can master it faster, thereby making it more efficient and easy to use.
Similarly, AutoCAD does not allow collaboration and is devoid of cloud features. However, the software used in BIM – ArchiCAD – comes with collaborative characteristics that enable multiple designs to work on a design at the same time.
Thus, in terms of software analysis, BIM stands out.
CAD vs BIM – Uses and Efficiency
CAD is used to reduce the challenges of manual calculations and design drafting in construction projects. All calculations of space are done by the software itself, thereby saving time and energy. The geometric accuracy of designs has increased considerably because of CAD. Therefore, it is a technology that has made the architectural and construction process much more efficient.
However, BIM is capable enough to perform all the functions of a CAD-based tool but takes the mechanism two notches higher. It enables all parties to access the entire lifecycle of the building’s construction process. And, unlike CAD which supports 2D models, BIM helps with the creation of 3D, 4D, 5D, 6D, 7D, and even 8D versions. Thus, BIM is the next-gen CAD, and it is far more useful and efficient.
So, there we have it, a crisp overview of BIM vs. CAD. BIM surpasses CAD in all domains, and it is high time that you take the assistance of a BIM outsourcing company India for your next project!
