How Do You Use an Intersection Curve in SolidWorks?

by

In SolidWorks, an intersection curve is a powerful tool that allows you to create a curve by intersecting two or more existing entities. This can be extremely useful when designing complex 3D models that require precise shapes and contours. In this tutorial, we will explore how to use the intersection curve feature in SolidWorks.

Step 1: Accessing the Intersection Curve Feature

To begin using the intersection curve feature, you must first activate it. To do this, follow these steps:

  1. Step 1.1: Open your SolidWorks model and navigate to the “Features” tab.
  2. Step 1.2: Click on the “Curves” dropdown menu and select “Intersection Curve.”

Step 2: Selecting Entities for Intersection

After activating the intersection curve feature, you will need to select the entities that you want to intersect. These entities can include planes, surfaces, edges, or curves. Here’s how to select entities:

  1. Step 2.1: Choose the first entity by clicking on it in your model.
  2. Step 2.2: Choose additional entities by holding down the Ctrl key and clicking on each one.

Note:

You can also use pre-selected sketches or edges as entities for the intersection curve feature.

Step 3: Modifying Intersection Settings

Once you have selected all the desired entities, you can modify various settings to control how SolidWorks creates the intersection curve. Here are some important options:

  • Compute Intersections: This option determines whether SolidWorks automatically computes the intersections as you select entities. If unchecked, you will need to click the “Compute” button manually.
  • Keep Intersection Points: Enabling this option will create sketch points at each intersection point.
  • Merge Tangent Curves: When enabled, SolidWorks merges tangent curves into a single curve instead of creating separate segments.

Step 4: Generating the Intersection Curve

After selecting entities and configuring the desired settings, you are ready to generate the intersection curve. Follow these steps to create the curve:

  1. Step 4.1: Review your selections and settings in the intersection curve dialog box.
  2. Step 4.2: Click on the “OK” button to generate the intersection curve.

Note:

The resulting intersection curve will appear as a sketch entity in your SolidWorks model. You can further edit and manipulate it using standard sketching tools.

Conclusion

The intersection curve feature in SolidWorks provides a powerful way to create complex curves by intersecting existing entities. By following the steps outlined in this tutorial, you can easily utilize this feature during your design process. Remember to experiment with different entity combinations and settings to achieve precise and accurate results.

Happy designing!
