Assembly in CAD refers to the process of combining multiple individual parts or components into a single, more complex model. This can be used to create a virtual representation of an entire product or system, and can be used for a variety of purposes, such as manufacturing, testing, and animation.
In assembly modeling, the user will typically start by creating or importing the individual parts that will make up the assembly. These parts can be created using part modeling tools in the CAD software, or imported from other sources. Once the parts are created or imported, the user can then use assembly tools to combine them together. These tools may include:
- Constraints: These are used to define the relationship between parts and control their movement. For example, a constraint can be used to fix a part in place or allow it to rotate or translate in a specific way.
- Mate: is a feature that allows the user to specify how two parts will fit together by aligning the edges, faces, or axes of the parts.
- Assembly feature: Some CAD software like Solidworks have the ability to create features that are specific to assembly like ‘Fastener’ which will help adding screws, bolts, and other similar items in the assembly.
Once the assembly is complete, the user can use the assembly tools to move, rotate, and otherwise manipulate the parts as a group. They can also create detailed drawings and technical documentation of the assembly, and use the assembly to create animations or simulations of the product in action.
Examples of popular CAD software that have assembly capabilities include SolidWorks, CATIA, NX, Pro-E, Inventor.Regenerate response
