Why 2D Drawings are Ineffective and Expensive in BIM?Tweet
2D structural drawings are becoming obsolete as digital BIM based workflow programs become more popular. Time, money, and resources can be saved by making live changes and sharing content. BIM should replace 2D drawings in projects for the following reasons.
Reorganizing everything in 2D drawing is one of the most challenging things to do. You should never wait until you have too many pieces to organize before creating different groups and layers. Separate fragments should be organized into their groups and layers so that they do not unintentionally merge.
Define 2D Drawings
2D drawings are two dimensional representations of objects or scenes. They are used in a variety of contexts ranging from engineering to design and are often used to communicate a design or idea to a team of people.
2D drawings can be used to represent the shape, size, and position of objects in a scene or to show the relationships between components in a system. They can be created using a variety of software programs and tools, including computer aided design (CAD) and vector graphics applications.
Too Much Labor
It is still contractually binding for many engineers to produce 2D drawings for the documentation of their 3D models. It is easier to share 3D models with field staff and other parties involved in the project.
You can work on 2D drawings of candleholders, wooden sculptures, lighting fixtures, plants, and other seemingly endless details. The downside is that all those assets can weigh down the design model and sometimes mask crucial components, such as layout and roominess.
It is too labor intensive and memory consuming to make changes to 2D drawings efficiently or accurately. 3D models, on the other hand, allow for automatic updates of all related documentation as well as instant sharing of updates.
People tend to hold on to paper drawings or 2D documentation out of instinctive resistance to change. Due to the fact that you have been using a system your entire career, you are comfortable with 2D drawings. The switch from hand drawings to CAD systems in architecture took time.
Model Development with BIM
Projects are made clearer with digitally constructible 3D models. Construction teams will have fewer RFIs and guesswork if the model is well developed and accurate. With high quality models, engineers and construction teams can fully understand complex conditions before work starts on site by constructing them first virtually.
By ordering and delivering materials in advance, waste can be reduced and money saved. Due to the speed of BIM, the project was completed ahead of schedule compared to traditional 2D methods.
Model Based Collaboration in Clash Based Construction
Achieving success on site relies on collaboration, model based design, and sharing model data. In addition to the accurate and high quality model based design, seamless collaboration and extensive use of models on site, any construction project was a great success while using BIM. Using and producing high quality, an accurate model was a seamless process for the design team.
Real Time & Accurate Modeling
The builders and precast manufacturers were able to access the model in real time using Tekla Model Sharing rather than a shared IFC model in a more accurate and visual manner.
All prefabricated structures and precast fabricators can now transfer structural model data directly from their structural model into their production management systems using accurate modeling.
A 3D model can automatically update all relevant documentation, and updates can be shared at any time. The benefits of BIM include the ability to make changes in minutes instead of hours, cutting materials to exact dimensions, and the ability to collaborate far more proficiently than ever before.
Importance of 3D Drawings in BIM
3D drawings in Building Information Modeling or BIM are a powerful tool for designing, constructing, and managing the lifecycle of a building.
BIM enables designers and engineers to create visual representations of a building in a 3D environment, allowing for more efficient communication between all stakeholders throughout the building lifecycle.
In 3D drawings, design elements such as walls, windows, doors, stairs, and other features of a building can be represented in a three dimensional space.

By using 3D drawings, architects and engineers can quickly identify potential issues with the design and make changes before the building is constructed. This makes the design process more efficient and cost effective.
