CAD, generative design and simulation

Design software is where many manufacturing costs are locked in, long before a part reaches the floor. The tools here cover CAD for modeling parts and assemblies, CAM for programming machines, simulation for checking designs, and newer AI features that propose shapes, predict performance or suggest toolpaths.

Autodesk Fusion, Siemens NX, SOLIDWORKS and Onshape are full CAD systems used across industries. Fusion and NX also include CAM and simulation, and Fusion offers generative design that produces part shapes from loads and constraints. Onshape runs in the browser with built-in version control. nTop focuses on computational design for lattices and complex geometry, often for additive manufacturing. Neural Concept learns from past simulation results to predict how new designs will perform. CloudNC CAM Assist suggests machining strategies inside existing CAM software.

Generative and AI design results need engineering judgment. A shape that meets the load case may be hard to inspect, clean or finish, or may only suit one manufacturing process. Check results in simulation, involve manufacturing engineers early, and confirm the design can be made with the machines and suppliers you actually use.

File formats and data management matter more than feature lists. Check how each tool exchanges models with customers and suppliers, how it handles revisions and drawings, and whether your team can keep working if a cloud service is unavailable. For CAM, confirm post-processors exist for your machines and controls.
