Home » What Is a Subassembly in Solidworks: An Overview

Subassemblies are an important concept in Solidworks, a 3D modeling software used for product design and engineering. Subassemblies are an essential part of the design process, as they allow a user to break down a complex product into smaller, simpler parts. In this article, we’ll provide an overview of what a subassembly is in Solidworks and how to create one.

Subassemblies offer a powerful way to model complex parts and products in Solidworks. By using subassemblies, users can quickly create complex models with fewer steps and less time. Subassemblies are also flexible, allowing users to make changes to individual parts and components easily and quickly. With this flexibility, users can quickly create more accurate models that are better suited for manufacturing and prototyping.

What is Solidworks?


Solidworks is a computer-aided design (CAD) and engineering software program developed by Dassault Systèmes. It is used to create 3D design models and drawings for a wide range of products and industries ranging from aerospace to consumer goods. It enables users to produce designs quickly, accurately and with a high degree of visual realism. Solidworks has a wide range of features, such as its parametric modeling capabilities and its built-in design rules, which make it an excellent choice for engineering and manufacturing professionals.

Solidworks is one of the most widely used CAD programs in the world today. It is used to design components, assemblies and systems for a wide range of industries, including automotive, aerospace, consumer goods, medical, and many more. It is also used in the design of consumer products, such as electronics, furniture, and appliances. Solidworks has become a powerful tool in product design and engineering due to its intuitive user interface, comprehensive feature set, and powerful simulation capabilities. It is also highly customizable, allowing users to tailor the software to their specific needs.

What is a Subassembly?

A subassembly is a type of assembly that is made up of components that are assembled together as one unit, but can then be further broken down into smaller components. Subassemblies are typically used in the manufacturing industry to make larger parts or products. These subassemblies can then be used as part of a larger assembly or as the finished product itself.

Subassemblies are used for a variety of purposes, including reducing the amount of time and labor needed in the production process, as well as providing a more efficient way to assemble complex components. As they are made up of smaller parts, they can also be easier to transport and store, which can help to reduce costs. Additionally, they can also be used to create custom designs, allowing companies to create unique products that are tailored to their specific needs.

Benefits of Using Subassemblies in Solidworks

Subassemblies in Solidworks are beneficial in many ways. Subassemblies are essentially smaller assemblies that are grouped together and can be used to create larger assemblies. Subassemblies allow the user to break down complex assemblies into smaller, more manageable pieces that can be easily edited and modified. This allows for faster and more efficient design changes than if the entire assembly was edited from start to finish.

The use of subassemblies in Solidworks also simplifies the process of creating drawings and animations. By breaking down the assembly into smaller components, it is much easier to document and animate each part. Additionally, subassemblies provide for better organization, as the user can assign each subassembly a unique name and description. This can make the process of locating and troubleshooting any issues much simpler. Finally, the use of subassemblies allows the user to take advantage of the powerful tools provided by Solidworks, such as the ability to copy, paste, and mirror components. All of these features make subassemblies an invaluable tool for creating complex assemblies.

How to Create Subassemblies

Creating subassemblies is a useful way to break down complex assemblies into smaller components to make them easier to manage. Subassemblies also allow for easier reuse of components for multiple projects. To create subassemblies, there are several steps that need to be followed. First, it is important to assess the assembly and identify the components that can be broken down into smaller pieces. Once these components have been identified, it is important to create a list of the parts needed for each subassembly. This list should include the component parts, the order they will be assembled in, and the location of each component. After the list has been created, the parts should be ordered and the assembly procedure should be documented. Once the parts have been received, each subassembly should be assembled in the order outlined in the list. After each component has been assembled, the subassembly should be tested to ensure it is working properly. Once all the subassemblies have been completed, they can be assembled into the larger assembly. This process should be repeated for each component in the assembly until the finished product is complete.

Using Subassemblies to Design Complex Parts

Subassemblies are an effective way to design complex parts. Subassemblies are components that are pre-assembled, so they can be quickly and easily integrated into a larger product. By breaking down a product into smaller parts, engineers can make sure that each component is designed in a way that optimizes the overall function of the product. It also allows for improved quality control, since each part can be tested independently before being integrated into the product.

Subassemblies can also help reduce production costs. By breaking down a part into smaller parts, manufacturers can reduce the amount of labour and materials required to produce the product. This can help reduce production time and cost, while also ensuring that the product is of a high quality. Furthermore, subassemblies can be quickly and easily replaced or updated, making them ideal for rapidly changing product designs.

Using Subassemblies to Make Assembly Drawings

Subassemblies are a great way to make assembly drawings easier to produce and read. Subassemblies are components, drawings, or other items that are grouped together in order to make the assembly drawing easier to understand. This can be done by using subassemblies to break down the assembly into smaller parts, which can then be more easily referenced. By breaking down the assembly into smaller parts, it will be easier to identify the individual components and their relationship to each other.

Using subassemblies also makes it easier to keep track of the parts that are needed to create the assembly drawing. With subassemblies, it is easier to quickly identify the parts that are needed and to make sure that they are all present. This can help to make sure that the assembly drawing is complete and accurate, which can save time and money when producing the assembly drawing. Subassemblies can also help to reduce the number of mistakes that occur when producing the assembly drawing, as it will be easier to identify any errors that may have been made.


In conclusion, Subassembly in Solidworks is a powerful tool for creating complex assemblies with ease. It enables the user to create large assemblies quickly, by using existing parts and components and combining them into subassemblies. Subassemblies can then be combined into a single assembly, reducing the time spent building and managing components and enabling faster design iterations. Subassembly in Solidworks also allows for easier troubleshooting and maintenance of assemblies, as the user can quickly identify and isolate the relevant components. With its intuitive user interface and powerful design features, Subassembly in Solidworks is an invaluable tool for designers to create complex assemblies quickly and accurately.
