How Do You Subtract a Body in SolidWorks?

Subtracting bodies in SolidWorks is a fundamental operation that allows you to create complex and intricate designs. Whether you are designing mechanical parts or creating assemblies, the ability to subtract one body from another can greatly enhance your modeling capabilities.

In this tutorial, we will explore the various methods of subtracting bodies in SolidWorks, including using the combine feature and using the cut feature. Let’s dive in!

Using the Combine Feature

The combine feature in SolidWorks is a powerful tool that allows you to perform operations such as adding, subtracting, and intersecting bodies. To subtract a body using the combine feature, follow these steps:

Step 1: Open your SolidWorks model

Firstly, open your SolidWorks model or create a new one by going to File > New > Part.

Step 2: Create two overlapping bodies

Create two 3D bodies that overlap each other. You can use basic shapes like cubes or cylinders to keep things simple for this example.

Step 3: Access the Combine tool

To access the combine tool, go to Insert > Features > Combine.

Step 4: Select Subtract operation

In the Combine dialog box, select “Subtract” as the operation.

Step 5: Select Target and Tool bodies

Select the body you want to subtract from (Target body) and then select the body you want to subtract (tool body).

Step 6: Click OK

Once you have selected both bodies, click OK. The Target body will now be subtracted by the tool body.

Using the Cut Feature

The cut feature is another method you can use to subtract bodies in SolidWorks. This method is particularly useful when you want to remove a portion of a body without affecting the rest of the model. To subtract a body using the cut feature, follow these steps:

Step 1: Open your SolidWorks model

Again, make sure you have your SolidWorks model open or create a new one.

Step 2: Create a sketch on the body

Select the face or plane where you want to perform the cut. Then, create a sketch that defines the shape of the cut.

Step 3: Access the Cut tool

To access the cut tool, go to Insert > Features > Cut.

Step 4: Select Through All option

In the Cut dialog box, select “Through All” as the end condition. This will ensure that the cut extends through the entire body.

Step 5: Click OK

Once you have set up your cut parameters, click OK. The selected portion of the body will be subtracted, leaving behind a void.

Tips and Tricks

  • Create sketches: When using either method, it’s essential to create sketches that define your desired cuts or intersections.
  • Edit features: If you make a mistake or need to modify your cuts later on, you can always edit features and adjust their parameters.
  • Use reference planes: Utilize reference planes to align and position bodies accurately before performing operations.
  • Combine multiple bodies: You can combine multiple bodies before performing operations like subtraction.

In conclusion, subtracting bodies in SolidWorks is an essential skill that allows you to create intricate designs and assemblies. Whether you choose to use the combine feature or the cut feature, understanding these methods will greatly enhance your modeling capabilities. Remember to experiment and practice to become more proficient in subtracting bodies in SolidWorks.
