What is Computer-Aided Drafting and Design (CADD)

Did you know that before the invention of Computer-Aided Drafting and Design (CADD) software, drafters and designers had to create models by hand using large sheets of paper and drawing boards? This process was not only labor-intensive but also very challenging to review and revise.

Fortunately, the field of engineering and design has undergone a revolution with the advent of CADD software. CADD is a software program used in architecture, engineering, and construction that makes it easier to sketch and create physical components or arrange procedures. One of the key advantages of CADD is its ability to streamline the design process. With traditional drafting methods, any changes or modifications to the design would require starting from scratch. However, with CADD, designers can easily make revisions, saving both time and effort. This flexibility allows for more efficient and accurate designs. Additionally, CADD software offers a wide range of tools and features that enhance the design process. These tools include the ability to create 2D and 3D models, generate detailed drawings, and analyze data. By utilizing these features, engineers and designers can visualize their concepts and identify potential issues. Another key advantage of CADD is that it also promotes collaboration among different firms involved in a project. With the software's ability to share and exchange design files, team members can easily communicate and work together, regardless of their physical location. This level of collaboration not only improves efficiency but also ensures that all parties are on the same page, reducing the risk of errors or misunderstandings. In terms of productivity, CADD greatly speeds up the design process. The increased productivity allows for faster project completion and ultimately leads to cost savings. This iterative process not only improves the quality of the final design but also fosters innovation and problem-solving skills. With its ability to create precise and accurate designs, CADD continues to shape the future of the industry, making it easier than ever to bring ideas to life.


 

What is Additive Manufacturing?

Did you know that additive manufacturing (AM) makes physical objects from 3D digital designs? AM is defined by GE Additive as “data computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes.”

Digital technology has been revolutionizing the engineering industry for decades, and AM brings a new and improved angle that will expand the range of designs. AM is capable of producing shapes that were previously unattainable using only metal powder material and a laser machine. Instead of molding or even machining, the laser machine can recreate and build up the 3D printing layer by layer, including the detailed structures on the inside. AM is so practical that engineers are able to make last minute changes to the 3D printing without delaying or ruining the object. Additionally, a large section of the 3D printing can be made as a single large piece instead of printing multiple smaller parts and then assembling them together. It is safe to say that as the industries become more aware of what AM is capable of doing and AM becomes more popular within industries, it will have a bright future due to its capability of working so well side-by-side with other technology, including machining. AM can also be utilized in other industries such as aviation and medical because it is capable of printing aircraft parts and medical devices, including creation surgical implants.

The Role of 3D Modeling in Researching the Human Brain

3D modeling was developed in the 1960s by the creator of Sketchpad, Ivan Sutherland, and is used to create a 3-dimensional digital representation of any surface or object.

A variety of fields utilize 3D modeling, including video games designers and movie / illustration animators, in order to bring their creative ideas to life. It is no surprise that 3D modeling is an important tool for many careers, including for engineers and architects. For example, engineers and architects use 3D modeling when planning and designing their work. This software helps engineers and architects save time and money by allowing scenario visualization before execution of their projects.

In the science world, 3D modeling has been a complete game changer, as scientists are using it as an advanced tool to study the human brain for common neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. After many failures of trying to convert the findings from animal-based cell models to human patients, brain cell models created with 3D modeling have many advantages including:

  • Replacing the old 2D model;
  • Minimizing failures by having better translations of the findings; and
  • Having a higher degree of improvements and solutions for various neurodegenerative diseases.
