Episode 3 - Typical systems for managing master data - Part 2

CAE stands for "Computer-Aided Engineering

It is a broad term that refers to the use of computer software and simulations to assist in various engineering tasks, including product design, analysis, and optimization. CAE tools and techniques are used in multiple engineering disciplines, such as mechanical, civil, electrical, and aerospace engineering, to simulate and analyze the behavior of complex systems, structures, and processes.

Common applications of CAE include finite element analysis (FEA), computational fluid dynamics (CFD), structural analysis, thermal analysis, and more. These tools help engineers and designers make informed decisions, improve product quality, reduce development costs, and speed up the design and testing process by allowing them to create virtual prototypes and perform simulations before physical prototypes are built.

MCAD (Mechanical Computer-Aided Design) and ECAD (Electrical Computer-Aided Design) are typically considered part of the broader field of CAE (Computer-Aided Engineering), but they are distinct subfields within CAE.

CAE encompasses a range of computer-based tools and techniques used in engineering, including simulations, modeling, and analysis. MCAD and ECAD are specialized branches within CAE that focus on various aspects of engineering:

MCAD (Mechanical Computer-Aided Design):

MCAD deals with the creation of 3D models and designs for mechanical and physical components, such as machinery, vehicles, and industrial equipment. It includes tools for drafting, modeling, and simulating the behavior of mechanical parts and assemblies.

Typical systems for MCAD (Mechanical Computer-Aided Design) are software applications and platforms that enable engineers and designers to create, model, and simulate mechanical components and assemblies. These systems are essential for various industries, including automotive, aerospace, manufacturing, and more. Some typical MCAD systems include:

• Autodesk Inventor is a widely used MCAD software that provides 3D modeling, simulation, and design tools for mechanical components. It's known for its parametric modeling capabilities.
• SOLIDWORKS is another popular MCAD software that offers 3D modeling, simulation, and analysis tools. It's known for its user-friendly interface and extensive capabilities.
• CATIA is a comprehensive MCAD and CAE software suite used in industries like automotive and aerospace. It offers advanced design, simulation, and analysis capabilities.
• PTC Creo, formerly known as Pro/ENGINEER, provides a suite of MCAD tools for 3D modeling, simulation, and analysis, including parametric and direct modeling capabilities.
• Siemens NX offers integrated MCAD and CAE solutions with advanced 3D modeling, simulation, and product lifecycle management (PLM) capabilities.
• Solid Edge is a versatile MCAD software from Siemens with features for 3D modeling, simulation, and data management.
• AutoCAD Mechanical is an extension of AutoCAD specifically tailored for mechanical design and drafting.

These MCAD systems typically offer features for 3D modeling, parametric design, assembly modeling, and simulation. The choice of MCAD software depends on factors like the specific industry, the complexity of the designs, and the preferences of the engineers and designers using the tools.

ECAD (Electrical Computer-Aided Design):

ECAD, on the other hand, is specific to the design of electrical and electronic systems, such as circuit boards and wiring diagrams. It involves software for schematic design, PCB layout, and simulation of electrical components and circuits.

Electrical Computer-Aided Design (ECAD) systems are software tools used for designing and simulating electrical and electronic systems, including circuit design, PCB (Printed Circuit Board) layout, and related tasks. Here are some typical ECAD systems:

• AutoCAD Electrical is used for electrical design and drafting. It's known for its integration with other AutoCAD products and a large user base.
• Altium Designer is a popular ECAD software for PCB design, known for its intuitive interface and a comprehensive set of features.
• Cadence Allegro is a widely used ECAD platform for PCB design, especially in industries that require high-performance designs and signal integrity analysis.
• Mentor Graphics (now Siemens EDA): Mentor Graphics offers several ECAD tools, including PADS and Xpedition, which are used for various aspects of PCB design.
• Autodesk Eagle is a popular choice for small to medium-sized PCB design projects. It is user-friendly and suitable for startups and hobbyists.
• SOLIDWORKS Electrical is part of the SOLIDWORKS ecosystem and is used for electrical design, providing integration with MCAD models.
• EPLAN is widely used in industrial automation and electrical engineering for comprehensive electrical design, documentation, and integration capabilities.
• Proteus is known for its circuit simulation capabilities, making it suitable for both electronic design and microcontroller-based projects.
• PROMIS-e is often used in industries requiring control system design and automation engineering.

The choice of ECAD software depends on the specific needs of the project, the industry in which it's being used, and the preferences of the design and engineering teams. Some software packages may be more popular in certain regions or industries due to their specific capabilities and features.

Storing ECAD and MCAD data is a critical part of the product development process.

The choice of where to store this data depends on factors like the size of your organization, collaboration needs, data security, and regulatory requirements. Storing ECAD and MCAD data, here's how these aspects apply to PLM systems:

1. Centralized Data Management:

• PLM systems provide centralized data management, just like PDM systems. They serve as a single source of truth for all product-related data, including ECAD and MCAD files.

2. Data Integration:

• PLM systems integrate various types of data, from CAD files to documentation, BOMs, and change orders. This integration ensures that all data related to a product is easily accessible and interlinked.

3. Version Control:

• PLM systems maintain comprehensive version control for all product data, including ECAD and MCAD files. This version history is crucial for tracking changes and ensuring data integrity.

4. Access Control:

• Access control in PLM systems is just as robust as in PDM systems. It allows organizations to define user permissions and restrict access to sensitive design data.

5. Collaboration and Workflow Management:

• PLM systems support collaboration among teams with workflow management tools that help streamline processes, facilitate design reviews, and coordinate tasks across various departments.

6. Concurrent Engineering:

• PLM systems, like PDM systems, facilitate concurrent engineering by enabling different teams to work simultaneously on various aspects of a project, reducing time to market.

7. Configuration Management:

• PLM systems provide advanced configuration management capabilities for managing complex products with various configurations, options, and variants.

8. Change-Management:

• Change management features in PLM systems are comprehensive, allowing users to initiate, track, and assess changes to both ECAD and MCAD data.

9. Data Reuse:

• PLM systems promote data reuse, reducing duplication of effort and encouraging the use of standardized components across different projects.

10. Reporting and Analytics:

• PLM systems typically include reporting and analytics tools to assess project status, performance, and compliance, including both ECAD and MCAD data.

11. End-to-End Lifecycle Management:

• PLM systems cover the entire product lifecycle, ensuring that data continuity and management are consistent from product conception to disposal.

12. Regulatory Compliance:

• PLM systems assist organizations in complying with industry-specific regulations and standards by maintaining detailed records of design changes and ensuring data integrity for both ECAD and MCAD data.

13. Traceability:

• PLM systems offer robust traceability features that enable organizations to trace design changes and decisions back to specific requirements, issues, or changes throughout the entire product lifecycle.

In summary, PLM systems offer the same advantages as PDM systems when it comes to managing ECAD and MCAD data. However, PLM systems extend these benefits across the entire product lifecycle, making them a more comprehensive solution for organizations engaged in complex product development that spans both electrical and mechanical domains. The choice between PDM and PLM depends on the specific needs and scope of your organization's product development efforts.

In summary, both MCAD and ECAD are subsets of CAE, each focusing on a specific discipline within engineering—mechanical and electrical, respectively. These tools are essential for professionals in their respective fields, and they can be used in conjunction with other CAE tools when a project involves both mechanical and electrical components.
