Create and manage assembly models of any size or complexity with powerful CAD assembly design tools. With both top-down and bottom-up techniques supported, you can manage and navigate assembly models and keep your team organized and on track:
- Handle complex assembly designs on the daily
- Access control structures and constraints for parametric assemblies that simplify design changes and accelerate modeling of configurations, options and variants
- Design in the true context of your product
- Validate your designs and identify and resolve issues with complete support of digital mockups
