How Do You Show Threads in SolidWorks Drawing?

When creating technical drawings in SolidWorks, it is essential to accurately represent threaded features. Threads provide vital information about the size and type of fasteners used in a design. In this tutorial, we will explore different methods to show threads in SolidWorks drawings, ensuring that your technical documentation is clear and informative.

Method 1: Cosmetic Threads

The easiest way to display threads in a SolidWorks drawing is by using cosmetic threads. Cosmetic threads are non-geometric representations of the actual thread form. They are simple to create and do not affect the model’s performance or file size.

To add cosmetic threads:

  1. Select the desired hole or cylindrical surface.
  2. Right-click and choose “Insert Cosmetic Thread” from the context menu.
  3. In the Cosmetic Thread PropertyManager, specify the thread parameters such as size, pitch, and display options.
  4. Click “OK” to apply the cosmetic thread representation.

Note: Cosmetic threads are solely for visual representation and do not provide any functional properties like interference detection or clearance checks.

Method 2: Model-Based Threads

If you require accurate representations of threads for manufacturing purposes or need functional properties associated with threaded features, model-based threads are the way to go. Model-based threads create an actual thread feature within your SolidWorks model, allowing for precise dimensional control and analysis.

To add model-based threads:

  1. Select the hole or cylindrical surface where you want to place the thread feature.
  2. Navigate to the “Insert” tab and click on “Thread.”
  3. In the Thread PropertyManager, specify the thread parameters such as size, pitch, and thread type.
  4. Choose whether you want to create an internal or external thread.
  5. Click “OK” to apply the model-based thread feature.

Note: Model-based threads provide accurate representations of threads with functional properties. However, they may increase file size and affect performance in large assemblies.

Method 3: Hole Callouts

Hole callouts are essential for providing detailed information about threaded holes in your technical drawings. SolidWorks enables you to automatically generate hole callouts that include thread information, such as size, pitch, and tolerance.

To add hole callouts:

  1. Select the threaded hole using the “Hole Wizard” or “Simple Hole” command.
  2. In the Hole Wizard or Simple Hole PropertyManager, specify the thread details like size and pitch.
  3. Click on the “Callout” tab and choose your preferred hole callout style.
  4. Place the hole callout on your drawing by clicking on the desired location.

Note: Hole callouts not only show threads but also provide additional information like depth, counterbore diameter, and more. They are crucial for manufacturing and assembly processes.

Tips for Displaying Threads in SolidWorks Drawings

  • Use consistent thread representations throughout your drawings to maintain clarity and avoid confusion.
  • Add dimensions to highlight critical thread features such as major diameter, minor diameter, or pitch diameter.
  • If working with large assemblies containing numerous threaded components, consider using simplified representations or configurations to improve performance.
  • Utilize annotations and notes to provide additional information about thread callouts, such as thread class or special tolerances.

By following these methods and tips, you can effectively show threads in SolidWorks drawings. Whether you opt for cosmetic threads, model-based threads, or hole callouts, ensure that your technical documentation accurately represents the threaded features of your design.
