Assembly
In CAD, an assembly refers to a collection of individual parts or components that are brought together to create a larger, more complex object or system. It represents the relationship and arrangement of these parts in a virtual environment.
In an assembly, each individual part is modeled separately and then combined to create a complete representation of the overall design. The parts can be standard components, such as screws or bolts, or custom-designed components specific to the project.
Assemblies are essential for representing complex objects or systems, such as machinery, vehicles, or buildings. They enable designers and engineers to visualize how the individual parts come together and interact, assess interferences or clashes, and verify the functionality of the design.

- Assemblies — roadmap (Shipped): Assemblies organize parts into structured systems with mates and motion to reflect real-world relationships.
- Assembly Mates — roadmap (In Progress): Intuitive mates to position, constrain, and move parts in realistic assemblies.
- Load Large Assemblies Fast — roadmap (Shipped): Keep large assemblies responsive during loading, editing, and review.
- Assemblies — roadmap (In Progress): Build, constrain, and manage multi-part designs with reliable assembly workflows.
