What is BIM and what is the difference between this methodology and traditional CAD? What's up Engineering Lovers, my name is Gustavo Pereira and today I'm going to show you the differences between BIM and CAD and leave an important tip. Technological improvements, linked to construction processes, are constantly evolving, from drawings developed in pencil and paper, to three-dimensional virtual representations with the inclusion of complex systems of production and development of projects.
Today the engineering market is becoming increasingly automated, with the use of 3D modeling tools that facilitate the visualization of the functioning of parts and the interface of projects from different disciplines. But for you to stand out in this market, you need to know 3D modeling. And to help you on this journey, I left in the description a link to a very good solidworks course, made by those who understand the subject.
This course will help you understand and master one of the most widespread 3D modeling tools on the market . from Solidworks. And even if you are a beginner or a layman, the course was designed so that you can start from scratch and understand the concepts and tools of the software.
As for you, who already have knowledge of the software, the course has usage tips that can facilitate the development of projects. Professor Edu is a specialist in project and product development with Solidworks, with over 14 years of experience in 3D modeling and has worked in the main official CAD training centers in the market such as Autodesk and Solidworks itself. So if you're interested, check out the link in the description and check out our course tip that can upgrade your professional career.
The implementation of CAD software, replacing pencil and paper, brought a better work methodology and efficiency in the treatment of projects. Through CAD systems, elements such as lines, points and texts are inserted into a virtual space through coordinate vectors with mathematical precision. Initially with two-dimensional projects, the famous 2D, CAD systems have evolved to offer 3D elements, the famous 3D, for the construction of surfaces and solids.
Despite this significant evolution, the way of designing in CAD systems cannot be considered a paradigm shift, since only the design tools were transferred to the computer, reducing errors, dedication time and providing greater ease for the application of necessary changes. . That is, the modeling became more efficient, but the final result was kept for representation purposes.
And that's where the evolution of the BIM concept was introduced. But what is BIM? BIM stands for Building Information Modeling, which in free translation is something like Building Information Modeling or Building Information Model BIM is a process for producing and managing “I” data, that is, all information from a project to construction.
, passing through the entire life cycle of the asset, simulating the real construction in a digital environment. The BIM concept provides for the construction in a virtual 3D environment of characteristic objects and not their representation. Such objects, called intelligent objects, present, in addition to the spatial properties associated with their representation, intrinsic properties.
That is, in addition to performing 3D modeling of objectives, you enter data such as material type, weight, strength, fatigue, and many other parameters. If we use the door object as an example, we will have in the CAD software the geometric representation of the object in a 2D or 3D environment. In the BIM concept, the door in question is a single entity with its geometric elements and other intrinsic properties.
In addition to the three dimensions of spatial geometric modeling, it is possible to assign new dimensions to the object, such as “time”, “cost”, among other possible variables. For this concept, the project no longer presents lines and texts to represent elements, but the objects that make up the work. In this way, BIM provides all the information necessary for drawings, graphic expression, constructive analysis, quantification of work and execution times, from the initial phase of the project to the conclusion of the work.
Another interesting point about the BIM methodology is the workflow. The dynamics in BIM is linked to the synchronization of dimensions, as I said earlier, we have, for example, the design dimension, the constructive dimension, the cost dimension and even time. And this integration of the model into the workflow requires a simultaneous collaborative aspect, that is, it allows different people to work at the same time on a single file on the server, and the software even updates all dimensions automatically.
While in CAD it would be necessary for one to send it to the other and from each change, the files would have to be resent or referenced over the other to look for incompatibilities or follow the work. Using the BIM methodology allows us to have: A transparent and open workflow A relevant database for use throughout the project lifecycle in one place Smart drawings with project information Integrated drawings and calculations Automatic updating of drawings and Automatic quantitative details And more accurate execution and greater assertiveness in schedules As you can see, the BIM methodology is a new step in the world of projects, and it is closely linked to 3D modeling. With it, you can link the flow of drawings with economic engineering and project planning and much more.
