Computer Aided Design (CAD) is the use of technological expertise to generate architectural and engineering blueprints. CAD design and drafting software allows users to use automated drafting rather than manual drafting. If you work in the architectural or structural engineering fields, then you have come across 2D and 3D drafting programs.
They help users explore different design ideas and visualize them through photo-realistic technology. Thus, users can have a better idea how a design will perform in the real world. CAD programs feature a variety of characteristics depending on whether you are using 2D (creates two-dimensional objects using vector-based graphics) or 3D applications (creates solid modeling surfaces). As such, this write-up looks at the different features of 2D and 3D programs.
Many computers are compatible with 2D CAD design and drafting software; however, 3D programs require high-performing machines with superior processors and display units. As such, users have to verify and upgrade the computer’s specifications before using 3D software.
Both programs are pretty efficient, but 3D CAD provides more functions to a designer. They include three-dimensional applications, unique reference views, faster product design, and designers can incorporate last-minute design changes. Besides, 2D CAD programs are digital drafting tools that allow designers to sketch layers, line weights, and line types. It’s up to the designers to create floor plans, elevations, perspectives and other useful characteristics for the project.
Although 2D CAD design and drafting software allow designers to construct three-dimensional views, 2D CAD programs do not have any rendering capabilities. As such, designers have to export the perspective to a different paint program to complete the rendering process. However, 3D CAD programs, have the ability to render real images of the construction model within the application.
Making changes 3D CAD programs allow designers to work with doors, windows, walls, curtains and other architectural components that contribute to the creation of a 3D model. For instance, to insert a door or window in space, 3D CAD software allows you to drag and drop the door. If using 2D CAD programs, however, you need to select and break the lines representing the wall or space you want to insert the door. This can be a pretty tedious process.
What’s more With outdated design process, change or editing anything can be challenging. As such, if you want to change anything, you might be forced to repeated the entire drafting process. Besides cost, the simplicity and precision of cad programs are key reasons why companies requiring 3D design services are advised to outsource this role to professional companies. With them, you get high turnarounds and quality outputs.
