3D modeling in combination with 2D design planning is one of the most important CAD trends of 2017-2018. What has long been taken for granted in the automotive industry is only very hesitantly establishing itself in architecture. Many of the respondents justify this with the increased effort. The opposite is true: the advantages clearly outweigh the disadvantages.
Digital working methods have long been standard for architects such as e-mail, smartphones, and tablets. Tendering, CAD software and calculation are common tools in everyday planning. But while the automotive industry offers self-steering models, many architects still use their CAD software as a drawing board. One reason for this is that the acceptance of 2D drawings is still there. On the other hand, a conversion also means the abandonment of habits and a time-consuming conversion of processes. Here you will find out 5 reasons why architects should rely on 3D planning.
1. Competitive thanks to 3D
In the meantime, more and more countries are recognizing the advantages of digital planning and developing uniform standards, and procedures in order to be able to use data more diversely. Once established, this will also have consequences for architects, as 2D plans will no longer meet the requirements. It is already clear today that if you want to remain competitive in the future, you cannot avoid 3D planning.
2. Various possibilities of visualization
Many architects use 3D models for presentation purposes at building owners, or investors, or in competitions. Most of the time these are 3D objects with realistic textures and surfaces for visual presentation. They are not comparable with real 3D models due to the lack of a database. A real 3D model is a digital image of the later building and offers various possibilities for further use already in the design phase – from virtual reality to 3D printing.
Virtual Reality makes the 3D model an almost touchable experience for planners and builders. How high is a ceiling, how large are the windows, how is the sun and shade throughout the year, what do different materials look like or what is the atmosphere of a room like? With the help of virtual reality, this information can be communicated much better than with classic renderings or videos. Planning errors are detected earlier and can be corrected before the start of the construction phase.
Using 3D printing methods, architectural or environmental models can be created within a short period of time, which is a great advantage, especially in competitions. Especially organic forms or filigree structures become touchable and understandable – in flexible scales and as a color print with realistic surfaces.
3. Time-saving and error avoidance
Nowadays, investors and building owners demand more than just flawless planning and construction of a building. Rather, they also require all building data for the following management. Many large architectural firms develop computer-generated forms in the early design phases and print them out with 3D printers. The advantages are obvious: The 3D model can be constantly changed and extended from the draft to the work planning up to the complete building, including room book, building services and furnishing with the involvement of all specialist planners. In contrast to the 2D working method, where all views and sections have to be updated manually with every change. Thus even the smallest changes can become a daily project.
4. More transparency in planning
In addition to saving time and avoiding errors, digital planning above all means transparency for all parties involved – across national and language borders: collisions can be easily identified, installation and maintenance scenarios can be checked at any time. The design can be more easily coordinated with engineers and building technicians. The quality of the services provided by the individual specialist planners can be checked more easily and the overall planning quality increases.
5. The introduction to BIM
In addition to geometric information, the 3D model can also be enriched with alphanumeric and physical information. This turns the “simple” 3D model into a BIM model. The BIM model is available to everyone involved in the project and serves to exchange information. It enables building and process simulations and creates all-embracing transparency in the life cycle of buildings.
