Understanding Assemblies

Understanding Assemblies: Assemblies are 3D files that allow designers to connect multiple parts or other assemblies to create a 3D model of an entire system, which visualizes how the entire product will fit together once it is fully assembled. Assemblies also document the bill of materials, a list of all components and their required quantities to build the product. This allows product designers and engineers to adjust and redesign the assembly to lower the manufacturing and assembly costs. Creating assemblies can be useful for creating much more natural objects, by using forming tools that make realistic-looking faces, animals, and smooth, curved surfaces. In order to fully define a part in its position, multiple mates may have to be applied. Assemblies also offer various movement options to accord with your design. By creating simple animations, designers can record video footage and easily show others how a mechanism works. In short, assemblies are an efficient and cost-effective way to design complex and natural-looking 3D models.

Placing Part Files

Adding parts to an assembly is the first step in creating a 3D model of your design. To do this, you can use the “Add Part” or “Insert Component” tools in your 3D modeling program. The first component you place will usually be “fixed,” meaning it won’t move. To fully define a part’s position in the assembly, you will need to apply multiple mates to it. Constrain parts in the assembly with mates so that they stay in place, or apply movement to create a motion design.

Joints and Movement in an Assembly

Joints are an essential aspect of creating assemblies and connecting parts in an assembly. You can use the joint tool to select multiple faces, edges or vertices on different components, and then connect them using mates. These mates allow you to fix components where they need to be, and restrict their motion in a particular direction or within a certain area. For example, you can create a rigid or planar mate to make two planes flush with one another, or a concentric mate to allow two cylinders to rotate around a common axis. Using mates, you can also create motion within an assembly by setting limits on the mate and allowing parts to slide along one another. The slider joint, for instance, is excellent for making the blade holder piece slide along the slot in the handle of a box cutter. By using joints and mates, designers and engineers can create fully functional 3D models that demonstrate how their products will move and function in real life.


Animations can be a great tool to use when presenting your 3D model. Creating simple animations is an easy way to show how the different components of your design work together, while also making it more interesting for viewers. Most design software comes with basic animation tools which allow you to create one or two moving parts. However, for more complex animations, using animation software like Autodesk Maya is recommended. With animation software, you can bring your designs to life, creating entire scenes and worlds to showcase your designs in action.

Appearance and Rendering

Appearance and Rendering: After assembling your parts, it’s time to make them look good. Appearance and material properties can add a realistic touch to your models. You can change the visual texture, color, or transparency of your part according to the material you want to simulate. Also, rendering software enables high-quality snapshot images of your model. It allows you to add lighting and shadows to the scene. With these features, you can precisely examine the aesthetics of your design. Don’t worry if your buddy drooles at the picture of the finish product, let them do it.


Conclusion: In conclusion, assembling your own PC using 3D models and motion designs can be both challenging and rewarding. Understanding assemblies, placing part files, using joints and creating motion, and adding animations and rendering can result in a visually stunning end product. With the right tools and knowledge, the possibilities are endless for creating your own unique design. Get started today and see what you can create!
