# How Do You Intersect Two Surfaces in SolidWorks?

In SolidWorks, there are several ways to intersect two surfaces. This can be useful when you want to create complex geometry or when you need to model the intersection of two parts. In this tutorial, I will show you how to use the Intersect feature in SolidWorks to achieve this.

## Step 1: Open SolidWorks

First, launch SolidWorks on your computer. If you don’t have it installed, you can download a trial version from the official website.

## Step 2: Create Two Surfaces

To demonstrate the intersect feature, let’s create two simple surfaces. Click on the “Sketch” button and choose a plane to sketch on. Draw a rectangle using the “Rectangle” tool and exit the sketch.

Note: You can use any kind of surface geometry for this tutorial. It doesn’t have to be a rectangle.

## Step 3: Extrude Surfaces

Select one of the surfaces and click on the “Extrude” button in the toolbar. Enter a value for extrusion depth and click “OK”. Repeat this step for the second surface as well.

## Step 4: Use Intersect Feature

Now that we have our two surfaces, we can use the Intersect feature to find their intersection curve. Go to “Insert” -> “Features” -> “Intersect”. In the dialog box that appears, choose your desired options and click “OK”.

• Select All: This option allows you to select all intersecting entities at once.
• Create Sketch: Enable this option if you want to create a sketch of the intersection curve.
• Merge Tangent Edges: If there are tangent edges at the intersection, enabling this option will merge them.
• Keep Tool Bodies: This option keeps the original surfaces intact and creates a new body for the intersection.

After selecting your desired options, click “OK”.

## Step 5: Review and Edit Intersection Curve

Once the Intersect feature is applied, you can review the resulting intersection curve. If you chose to create a sketch, it will be added to your feature tree. You can edit this sketch using SolidWorks’ sketching tools.

To Edit Intersection Sketch:

1. Select the intersection curve in the graphics area or feature tree.
2. Edit the sketch using available sketch tools like Trim Entities or Modify Dimension.
3. Exit the sketch when you’re done making changes.

## Step 6: Use Intersection Curve

Now that we have our intersection curve, we can use it for various purposes:

• Create new geometry based on the intersection curve.
• Create a boundary surface between two intersecting bodies.
• Create a split line on a surface using an intersection curve.

The possibilities are endless depending on your specific modeling needs!

### In Conclusion

The Intersect feature in SolidWorks provides a powerful toolset for working with intersections of surfaces. By following these steps, you can easily create and manipulate intersection curves according to your design requirements. Remember to experiment with different options and explore how this feature can enhance your modeling capabilities in SolidWorks!
