To begin, make sure you grasp the terms BIM and CAD. BIM is an abbreviation for Building Information Modeling. It is an integrated process based on coordinated, trustworthy information about a project from conception to completion. You can become a professional in BIM by opting for the BIM online certification course.
CAD stands for Computer-Aided Design. You can also include a D for Computer-Aided Design and Drafting. CAD is basically the use of computer technology to aid in the design process. While BIM tools like Revit are technically CAD systems, the name “CAD” is more commonly associated with drawing software. In the context of architectural design, CAD is the use of a drafting program, such as AutoCAD, to construct lines and arcs to depict a building design.
Consider a simple example to better grasp the distinctions. The layout labeled “CAD” on the right is identical to the layout labeled “BIM” on the left. When you choose one of the CAD walls on the right, you will notice that it is only a line. Two parallel lines have been drawn to indicate a wall. The only option available in the Properties panel is the Line Style. When you choose a BIM wall on the left, though, you can see that it is a real wall element. There are various settings in the Properties menu that may be used to define the wall.
When you select Edit Type, the Type Properties box opens, which contains all of the parameters that define this wall type. All of these criteria are applicable to schedules and tags. Actual elements are used to represent real-world components in the BIM technique. They are not simply three-dimensional components, but they also have parameters encoded into them.
In both the BIM and CAD examples, four walls and two doors were added to the floor plan view. The BIM tools in Revit, on the other hand, allow actual building elements to be put into a model, and they display in all views where their visibility is enabled.
When utilizing CAD for building design, you mostly focus on making drawings. When utilizing BIM, you focus on constructing a building model from which drawings may be created. As you don’t have to sketch the same item again, this saves time. Typically, floor plans are drawn first, followed by sections in CAD. However, with BIM, you construct the elements in a single view, and they display in all views where their visibility is enabled.
Furthermore, the parameters that are encoded into the elements may be simply utilized when it comes to documenting your design with tags and schedules. This saves time when updating building components and reduces problems because a component is not marked differently in two views.
Conclusion
Finally, Revit is not a BIM tool. Revit was created with BIM in mind; however, it does not cover all facets of BIM. When creating a building model with Revit, you can quickly export the model to other applications to make higher-quality renderings, do analyses, collaborate with other disciplines, fabricate pieces, and so on. Many of these features are not available while using CAD. As a result, compatibility with BIM is significantly improved. To know more about the best course after civil engineering, click here.
