Automotive vehicle design with CAD software

Leverage seamless integration of NX X with with Teamcenter, Siemens' product lifecycle management (PLM) software. This enables:

• Concurrent engineering: Work on different parts of the same assembly with other users.
• Version control: Ensure you're working on the latest design iteration.
• Change management: Track modifications and approvals.

Work on designs simultaneously in a cloud-based or networked environment. Key features:

• Multi-user collaboration: Receive live updates from multiple designers on the same project.
• Cross-functional collaboration: Interact with other users across different disciplines such as mechanical, electrical, and manufacturing teams.

• 3D annotations & PMI (product manufacturing information): Communicate manufacturing data within the CAD model.
• Redlining and commenting: Markup designs, suggest changes and add feedback directly in NX without altering the model.

• Browser-based access: Work remotely without needing a powerful local machine with the NX X Remote Add-on.
• Collaboration via Siemens Xcelerator: Share designs, perform real-time simulations and validate changes.
• Teamcenter Share: Collaborate and share product information with external stakeholders that don't have Teamcenter with browser-based instant access.

• NX Realize Shape: Use subdivision modeling methods to create advanced 3D product shapes with smooth, organic surfaces for exterior styling.
• NX Topology Optimizer: Automate lightweighting and improving structural performance of body panels while maintaining safety and strength and meeting material and manufacturing requirements.
• NX Advanced Sheet Metal: Model complex sheet metal parts that contain drawn features and nonlinear bend lines. Basic sheet model capabilities are included OOTB with NX, so you can easily design body panels, hoods and other stamped components commonly used in vehicle manufacturing.
• NX Advanced Convergent Modeling: Work with mesh geometry and data from 3D scanners, polygon modelers, simulation software and topology optimization. Basic convergent modeling capabilities are included OOTB with NX, so you can easily translate clay models into CAD data by converting scanned data into facets.

• Mastertrim: Create transportation seat trim and interiors from styling through manufacturing.
• NX Realize Shape: Design freeform, organic interior components such as dashboards, seats and trim.
• NX Render: Render photorealistic images of your interior or exterior designs for validation, review and marketing.
• NX Composites: Engineer and manufacture dashboard components, seats or interior panels with lightweight fiber-reinforced composite materials.

• NX Motion: Predict and understand the kinematics and dynamics of powertrain systems such as crankshafts, gears and camshafts.
• NX Topology Optimizer: Reduce weight while maintaining strength and performance in powertrain structures such as brackets and housings.
• NX Routing Harness: Route an electrical wiring harness consisting of bundles of wires and specify typical mechanical parts and supporting equipment.
• Other NX routing add-on modules: Design and route piping, cabling and harnesses for vehicles with 6 modules for routed systems design and 3 modules for electrical systems.

NX CAD also includes seamless integration with other Siemens Xcelerator applications that assist with vehicle design and development such as:

• NX for manufacturing: Optimize the manufacturing process for powertrain components such as engine blocks and transmission cases.
• Capital: Rapidly design, iterate and optimize E/E systems in vehicles; and dive deeper into electrical systems and wire harnesses design/manufacturing.

Streamline the design process and reduce the time required to create complex automotive components with automation in NX CAD. Quickly iterate on vehicle body structures, powertrain components and interior layouts while ensuring compliance with industry and company standards by leveraging automation workflows. For design, automation in NX can generate parametric models, apply design constraints and instantly update geometries based on predefined rules. By automating simulation and validation, you can perform rapid testing of different design configurations without extensive adjustments.

Balance performance, cost and manufacturability in automotive design with AI-enabled optimization in NX CAD. By leveraging generative engineering, powered by topology optimization and AI-enabled simulation, you can automatically refine structures to minimize weight while maintaining strength and safety. You can use optimization tools to analyze multiple variables, including aerodynamics, material efficiency and thermal performance. This allows you to make data-backed decisions to improve overall vehicle performance, especially in lightweighting for electric and fuel-efficient vehicles.

Optimize material selections for sustainability and lightweighting with embedded databases in NX. Take advantage of advanced material libraries to compare environmental impacts of different materials such as recycled composites, bio-based polymers and high-strength lightweight alloys. You can also leverage topology optimization, generating efficient structures with minimal raw material usage while maintaining strength and durability in order to reduce material waste.

Assess aerodynamics, thermal management and powertrain efficiency with simulation tools in NX to ensure energy efficiency, which is critical in sustainable vehicle design. Reduce energy consumption by optimizing airflow and cooling systems with computational fluid dynamics (CFD) and thermal simulations.

Improve battery cooling and aerodynamics in electric vehicles (EVs) to enhance range and efficiency, lower energy consumption and reduce emissions.

Put environmental impact reporting at the heart of your product lifecycle with NX Design for Sustainability. With this design-native sustainability impact analysis tool, you can evaluate the impact of design decisions based on a comprehensive set of environmental impacts—including carbon footprint equivalent—bringing rich environmental impact assessment to the formative stages of design, "shifting left" and covering the complete product lifecycle and digital thread.

Ensure compliance with global sustainability standards (such as EU REACH, RoHS, and US EPA guidelines) as environmental regulations become stricter with NX CAD. Leverage built-in compliance checks that flag materials and design elements that do not meet sustainability and emissions requirements to avoid costly redesigns and legal issues. Through this proactive approach, you can streamline the certification process for electric and low-emission vehicles.

Develop cutting-edge sustainable features such as lightweight composite structures, aerodynamic enhancements and 3D-printed components that reduce waste. Create ultra-efficient structures that require fewer materials while maintaining safety and performance with AI-enabled generative design. Design for sustainable manufacturing with tools for additive manufacturing and closed-loop material recycling.
