Mechanical product design software

Boost product design efficiency and quality with a powerful, integrated suite of computer-aided design (CAD) solutions. Remove barriers to innovation, design for sustainability and reduce development costs using our scalable, adaptable solutions for businesses of all sizes.

Accelerate mechanical product design

Customers demand complex, high-quality and sustainable products that are delivered fast. To stay competitive, you must develop and release innovative designs that meet the needs of a changing market in less time, at premium quality, with fewer issues and at competitive prices.

The problem in product design today is that many companies still use disconnected legacy design systems that do not support a holistic next-generation product design approach. To be successful, design must be fully integrated with simulation, validation, manufacturing and the rest of the product development process.


History-based modeling is rigid

62% of engineers agree that history-based modeling can be powerful but inflexible. Concept design is slowed by pre-planning, imported models have to be recreated and making late-stage design changes is difficult.


Rapid initial design creation is essential

49% of CAD users rank the ability to rapidly create initial designs as a significant concern, and an additional 40% say the ability to reuse existing designs is a top priority.


Upstream and downstream collaboration is critical

22% of CAD users say that collaboration with internal teams or design and manufacturing partners is a top challenge.

How can you design and deliver next-generation, high-quality products to market faster?

Implement an integrated mechanical product design solution to accelerate decision making and go-to-market. Increase productivity by up to 60% by enabling collaborative, simultaneous design across the globe.

Before the adoption of NX, our development cycle took 12 to 14 months; with NX, we’ve reduced our development cycle to six to eight months. This is a significant result, not just because costs have been cut proportionally, but mostly because the capacity of our product development department has increased to such an extent that we can create an additional model each year.

Frequently asked questions

Mechanical product design software solutions, also known as CAD, enable collaborative and simultaneous design across global teams. This increased flexibility helps companies improve quality and time-to-market while reducing costs. It allows engineers to reuse designs, easily share data, reduce complexity and ensure sustainability. Mechanical design software also allows for easy modifications and experimentation with designs to enable smooth customization.

Mechanical product design software solutions support every aspect of product development and can help your company gain a competitive edge. These solutions allow you to reuse designs, which will help you save time and ensure quality since the designs were already approved. You can easily modify and experiment with designs, which is especially helpful if you have to make changes frequently. Mechanical product design software solutions seamlessly integrate with other solutions to provide a more seamless and efficient design process.

What is CAD?

Computer-aided design (CAD) is the use of computer programs to create, modify, analyze and document two- or three-dimensional (2D or 3D) graphical representations of physical objects as an alternative to manual drafts and product prototypes. CAD is widely used in computer animation and media special effects as well as in product and industrial design.

What is NX CAD?

NX CAD is a mechanical product design solution developed by Siemens that helps companies boost product design efficiency and quality. It enables the most comprehensive digital twin of the product by seamlessly connecting teams, processes, systems and data involved in the product design.

It is the first major mechanical computer-aided design (MCAD) system to be certified as an open system that provides easy integration and has a proven track record of helping customers advance their data without disruption. It is the only CAD solution to support token licensing, a highly flexible approach to delivering add-on solutions. It is now available on the cloud, as-a-service (NX X), to help you accelerate your digital transformation easier, faster and at scale.

What is Solid Edge CAD?

Solid Edge CAD is a Siemens technology that engineers, product developers and designers use to create functional, virtual prototypes of three-dimensional objects. With Solid Edge, designers can dynamically create and modify every detail of a product, part or assembly. 3D CAD software facilitates and automates other aspects of product engineering, such as simulation testing, drawing and drafting, manufacturing, data management, computer-generated animation, and more. These three-dimensional models can be used in simulation studies to predict how the object will respond to stress and environmental factors, they can be rendered to create photo-realistic images for use in sales and marketing materials and/or detailed drawings can be sent to manufacturing for production (or, in the case of additive manufacturing, the CAD file can be sent directly to a 3D printer).

Modeling in CAD

Traditionally, there are two main approaches to creating and modifying geometry in 3D CAD: history-based (also known as ordered or feature-based) modeling or direct modeling. In history-based modeling, the structure and order of features control how models react to changes or edits. This creates predictable results from edits on underlying feature sketches using precise dimension changes. Direct modeling doesn't maintain a history of features or record how a model is built. There are no sketches driving features that make up the part. Editing is done by simply selecting what you want to change and changing it.
