FUSION - Modéliser une vis en 3D simplement

Introduction

In this tutorial, you will learn how to model a screw in 3D using Autodesk Fusion 360. The tutorial covers two different methodologies, making it suitable for both beginners and intermediate users. By the end of this guide, you will have a solid understanding of how to create a screw model and utilize basic features of Fusion 360.

Step 1: Setting Up Your Workspace

• Open Autodesk Fusion 360.
• Create a new design by selecting "File" and then "New Design."
• Familiarize yourself with the user interface, including the toolbar, browser, and canvas.
• Make sure your units are set correctly (millimeters or inches) by navigating to "Document Settings" in the browser.

Step 2: Creating the Screw Head

• Select the "Sketch" option from the toolbar.
• Choose the appropriate plane (top, front, or right) to sketch the head of the screw.
• Use the "Circle" tool to draw a circle that represents the diameter of the screw head.
• Dimension the circle using the "Dimension" tool to ensure accuracy.

Step 3: Extruding the Screw Head

• Finish the sketch by clicking "Finish Sketch."
• Select the circle you just created and click on the "Extrude" option in the toolbar.
• Enter the desired height for the screw head and confirm the operation.

Step 4: Sketching the Screw Shaft

• Start a new sketch on the top face of the screw head.
• Use the "Circle" tool again to create a circle for the shaft, ensuring it is concentric with the head.
• Dimension this circle to define the diameter of the screw shaft.

Step 5: Extruding the Screw Shaft

• Finish the sketch and select the new circle.
• Click "Extrude" and specify the length of the screw shaft.
• Confirm the operation to create the shaft.

Step 6: Adding Threads (Optional)

• If you want to add threads to the screw:
  • Select the shaft of the screw.
  • Use the "Coil" tool to create a helical thread.
  • Adjust the parameters such as diameter, pitch, and revolutions to achieve the desired thread profile.

Step 7: Final Adjustments

• Rotate and inspect your model to ensure everything looks correct.
• Use the "Fillet" or "Chamfer" tools to smooth any edges if necessary.
• Save your work regularly by selecting "File" and then "Save."
