Mechanical Design

Mechanical design is a complex and multifaceted process that aims to create machines, tools, mechanical devices and complex products capable of meeting specific standards of functionality, efficiency and safety.

This process is not only limited to design, but also consists of careful analysis of the needs of the project, the selection of appropriate materials, the verification of performance through simulations and especially the’intervention of different actors (design department, production, purchasing department…).

The fundamental goal of mechanical design is the creation of products that are not only reliable, but also optimized for their specific applications. This discipline finds application in many industries, including: automotive, aerospace, defense and manufacturing.

During the design process, designers create 3D models with the help of Computer Aided Design (CAD) tools to visualize and refine their designs, which are then subjected to simulations to predict product behavior under various operating conditions. One of the most critical aspects of mechanical design is a solid understanding of the fundamental principles of mechanics such as: knowledge of forces, stresses and strains, as well as a deep understanding of materials and their properties;. Choosing the right material, in fact, can significantly affect the durability, efficiency and safety of the final product.

The choice of CAD software is determined by a number of crucial factors:

1. Project size and complexity: larger and more intricate projects require more advanced and versatile software solutions.
2. Application Sector: sectors such as automotive, aerospace and manufacturing have specific technical and regulatory requirements
3. Designer's preferences and habits: can influence the choice, as usability and familiarity with the interface can increase work efficiency
4. External suppliers with whom to communicate using one CAD solution over another

Compared with major competitors, Siemens' Solid Edge and NX offer advantages such as:

• One single model, not three files to keep in sync: CAD, CAM, and CAE share the same associative model. A change to the geometry automatically updates the linked machining path and flags where the previous simulation is no longer valid, instead of having to manually resynchronize separate software tools
• Synchronous modeling, not just parametric: you can edit a face of the model directly without rebuilding the entire feature tree — useful for files imported from other CAD systems and for those who don't work in a CAD environment every day
• No conversion needed between NX and Solid Edge: the two lines share the same Parasolid geometric kernel. A file moves from one to the other with full fidelity, without going through exchange formats like STEP or IGES — useful when a supplier works in one environment and the end customer in the other
• Integrated data management with Teamcenter: version control, bill of materials, and collaboration across different sites all stay within the same Siemens ecosystem
• A licensing model that grows with the company: desktop or cloud, and in the cloud, four increasing tiers (Essentials, Standard, Advanced, Premium) for both lines. You can start with a base tier and add capacity only as the project requires it
• Two lines for different needs, not a one-size-fits-all compromise:Solid Edge for manufacturing SMEs working with sheet metal, frames, and medium-sized assemblies; NX for complex assemblies, multi-axis machining, and multidisciplinary simulations

Integration of Solid Edge and NX with Siemens' Teamcenter Product Lifecycle Management (PLM) platform enables centralized management of project data, improving collaboration between teams, reducing communication errors and optimizing overall workflow.
