CAD computer-aided design

What is CAD (computer-aided design)?

CAD (computer-aided design) is the process of digitally creating design simulations of real-world goods and products in 2D or 3D, complete with scale, precision, and physics properties to optimize and perfect the design before manufacturing. It is also known as CADD (computer-aided design and drafting).

CAD software is used by various types of engineers and designers to produce 2D and 3D models and drawings, allowing for efficient collaboration, review, simulation, and editing of designs.

The role of CAD in product development

CAD plays a core role in product development and manufacturing by enabling the creation of digital models that represent the physical characteristics of products. These models can be easily shared, reviewed, and edited using 3D CAD, which helps in bringing new, unique items to market more quickly and efficiently. CAD software has replaced traditional manual drafting methods, offering advantages such as increased precision, reduced errors, and improved collaboration.

What are the benefits of CAD?

3D CAD has revolutionized the way designers, engineers, and architects approach their work, offering a wide range of benefits that enhance efficiency, accuracy, and creativity while streamlining the entire design-to-production process.

Mitigate risks

Detailed visualizations and simulations help identify potential risks early in the design process, mitigating issues that could arise during manufacturing or implementation.

What’s the best way to implement CAD in your organization?

Getting started with CAD best practices in your organization requires a structured approach to ensure a smooth implementation, maximize efficiency, and align the system with your team’s needs and goals.

Begin by identifying tasks that the new system can do well, such as repetitive tasks or designs that are variants of a similar structure. This will help generate buy-in from designers, administrators, and executives.

Create a detailed schedule and budget for the implementation process. This plan should include objectives, descriptions of work to be done, costs, personnel resources, and a schedule.

Update drafting standards to include 3D methods. This will ensure that the time spent on establishing standards for 3D CAD will be recouped many times over the life of the system.

Train all the people involved in the implementation process. This includes designers, administrators, and support staff. Training should be included in the implementation budget and schedule.

Before deploying new CAD software, create templates for parts, assemblies, and drawings. Templates provide a consistent starting point for each new drawing and model, saving designers time and effort.

Verify the requirements of your new CAD system and ensure that all the hardware, software, and services are in place.

Create and manage your own CAD standards and guidelines for your design projects. This includes defining objectives, researching best practices, creating your own standards and guidelines, and implementing them in your CAD software and projects.

Regularly review and update your CAD performance and quality according to your objectives and expectations.
