What is Revit?


What is the difference with the Traditional CAD Workflow?


In the past, people were drafting on paper (2D). This was very difficult for them and for the whole industry. So, when the technology started to be used into the practice, they figured out the CAD (Computer-aided design) workflow was a lot smoother. Тhis necessitated people to switch all of the workflow from paper to digital CAD drawings.


This wasn’t so difficult for the industry because the change wasn’t in the workflow but it was in the deliverables of the data. Instead of drawing in 2D on paper, they were doing it in 2D on the digital platform.




What happened to the workflow after BIM?

Nowadays, when we are talking about BIM (Building Information Modeling) there is a huge switch into the workflow. That’s why BIM is so revolutionary. Now, it’s not only about using a software that allows you to convert things into 3D, but it’s actually a new mindset, new way of communication and collaboration. That was a big challenge since the building industry is very traditionalized.


This could bring issues with moving out of the comfort zone, because this could be recognized as a risk, as additional effort or cost. So, this is the reason for many in the industry to not want to invest in something they are not familiar with.



BIM as a buzzword


BIM became a “buzzword” within the industry because people were not completely sure of its meaning. Most of them think that BIM is equal to Revit but BIM actually is far more than that. Revit is a small part of the BIM process, and it’s more about the design part of it. It is a software that enables collaboration between designers and stakeholders. To understand it better lets immagine BIM as a huge cloud with a big amount and diversity of software, products, workflow, standards and technologies. So, it will be wrong to put limitations with just Revit. However, Revit is the most popular software used in the industry.







Revit and Traditional CAD

When it comes to comparing Revit to Traditional CAD, for instance to Rhino or AutoCAD, there is a huge difference. With Rhino or AutoCAD generally are used layers and in most cases the work is on 2D. There is, of course, an option for working with 3D but fundamentally working in 3D and 2D in AutoCAD is the same. Meaning generally it’s done by layer work and it’s all about how you are going to name that layer. For example, you can do a wall, but also you can call it a window or a door, and that’s becoming a representation of all the data. In this case it’s clear that the data could be not much accurate and that could cost many issues.


In Revit the actual construction is a data and every software reads it in the same way. Hence, if you create a door in Revit, the another softwares and platforms will accept the information and will detect it as a door. This brings a lot more clarity and prevents mistakes that could be very time consuming.


Another privilege of Revit software is that whilst you are working on the 3D model you are working with 2D drawing as well. So, basically you are working on the 2D documentation along with the 3D BIM model. This is extremely beneficial because you are saving a lot of time and you are able to detect some errors, design mistakes or other issues, and to repair them on time.



Extract Schedules Directly in Revit


Another benefit of using Revit is the possibility to extract schedules. When you build your 3D model, since the software is intelligent enough, it understands all the components, categories, walls, floors, and ect, and you could extract all the schedules right away. You are able to extract all the bill of quantities (BOQ), add filters, sort the different groups, insert formulas directly into Revit.


Although, it’s a great tool with many options for the whole BOQ, Revit would not be enough. The reason is that you most probably will need information about the area of the formwork or other features that are not included in the design model. For that you would need softwares like Navisworks that allows you to do cost management and cost calculations.




Revit Collaboration


It allows multiple stakeholders to get insight into the Revit model and to work together. This could be also a bit confusing for those who are used to the Traditional workflow. They have concerns that if they made some changes, somebody else could get it and mess up with his work or will delete some important information. Fortunately, there is nothing like that. Actually, the organization of the workflow is much more advanced. There are worksets, there are rules, ownership, borrowing items, so chances for mistakes are minimized.


Revit enables us to create 3D digital data into the digital model which can be collaborated between stakeholders. The software can ensure that the collaboration and the communication is efficient throughout the project lifecycle. Revit is a BIM design modeling tool and it’s one of the most advanced and used one into the BIM industry. It could help to process into the project to go smoothly and to minimize the errors.
