Today, designers and architects use computer-based 3D modeling software to create a three-dimensional representation of a particular design. 3D modeling gives that extra dimension to 2D drawings which assigns a perspective unto them and brings them to life.
Three Dimensional Modeling originated in the 1960s at the hands of the creator of Sketchpad, Ivan Sutherland, and it has been continuously inspiring manufacturing and architectural processes ever since. “Imagine being able to experience a place without actually being there, like a tour of the Acropolis of Athens from the comfort of your reclining chair” explains Aditya Yadav, an expert in structural and material science and one of the world’s top names in architectural precast designing.
3D models are created using software applications like AUTOCAD which usually work on the photogrammetry process and allow incorporating real-time data into the models and interact with the objects using a computer.
Traditionally, models were made using physical materials such as cardboard, clay, wood, etc., to get an idea of what the structure would look like after completion. The technology of 3D modeling has given rise to new benchmark trends and transformative technologies in the architecture industry.
At present, a specialized form of 3D modeling, known as 3D rendering or 3D visualization, is incubating complex feats of modern architecture.
3D Modelling and Precast UHPC Elements
The concept of design has changed drastically with the advent of precast concrete, particularly Ultra High-Performance Concrete (UHPC). UHPC has revolutionized façade design with its amazing versatility that enables casting thin curved sections that are strong and far superior in appearance at the same time.
Aditya Yadav has done extensive work on UPHC and is one of the few individuals capable of producing this kind of material. He delved deeper into the subject and shared that the design possibilities with UHPC are endless since it uses fiber reinforcement such as steel fibers, glass fibers, polyvinyl chloride (PVC) fibers, and shredded fabric instead of long reinforcement bars.
These UHPC elements can also be combined with stone, wood, ceramic, brick, and terracotta to form precast veneer-faced cladding elements that span multiple floors.
“Finely graded particles used in UHPC provide a dense and smooth finished surface and help closely transfer details from the form to the surface. These fine details can also be viewed using 3D rendering allowing clients to view the work before it is actually cast.” says Yadav.
The role of 3D modeling is extremely important in architectural precast designs. It not only gives a visual of what the design will look like but also enables designers to experience it through 3D rendering. This broadens the designer’s scope to utilize space and design concepts to the maximum possible limit.
3D rendering uses the high screen resolution and color displays of modern computers enhancing its realistic appeal with true colors, building material textures, and realistic backdrops. These renderings can be viewed from any angle, and have interactive capabilities like walkthroughs, flythroughs, panoramic views, etc. Clients are able to have a complete visual experience inside and out, of what they will actually experience upon the completion of a project.
Talking about the efficiency of the 3D modeling process, Aditya shares that it also helps reduce the cost of rework or rejection as it presents an exact representation of the project before it is actually executed in the flesh. In addition, 3D modeling results in increased productivity and fewer changes at the production stage by controlling the margin of error. It allows for all trial and error to be performed during the 3D modeling stage with the highest order of accuracy currently known in the industry.
3D rendering has enabled many architectural firms to make their marketing tactics more effective as it increases interest and engagement. It goes without saying that 3D modeling techniques are rapidly redefining architectural precast design, and now is the right time to engage it fully.
