Using the Extrude Tool in Fusion 360
Introduction
The Extrude tool in Fusion 360 is a fundamental feature used in 3D modeling. It allows you to convert 2D sketches into 3D objects by extending them along a specified path. This technique is essential for creating solid parts, modifying existing geometry, and building complex designs.Understanding the Extrude Tool
Extrusion involves taking a 2D profile and pulling it in a direction to create a three-dimensional shape. The Extrude tool can be used in various ways, such as: - Adding Material: Create solid objects by pulling material outwards. - Removing Material: Cut into existing solids to create holes or complex shapes. - Creating New Bodies: Form new 3D bodies from sketches.How to Use the Extrude Tool
Step-by-Step Instructions
1. Create a Sketch: Start by creating a 2D sketch on a plane. Use the Sketch tools to draw the desired shape. For example, draw a rectangle.
2. Activate the Extrude Tool: After completing your sketch, go to the Solid tab and click on Create > Extrude.
3. Select the Profile: Click on the profile you want to extrude. If you have multiple profiles, hold down the Ctrl key (or Cmd on macOS) to select multiple profiles.
4. Set the Direction: Choose the direction of the extrusion: - One Side: Extrude in one direction. - Two Sides: Extrude symmetrically in both directions. - Symmetric: Extrude equally in both directions from the center.
5. Specify the Distance: Enter the distance you wish to extrude the shape. For instance, extruding a rectangle by 20 mm. 6. Choose the Operation: Select the operation you want to perform: - Join: Combines the new shape with existing bodies. - Cut: Removes material from an existing body. - New Body: Creates a separate body from the extrusion.
7. Complete the Extrusion: Click OK to finalize the extrusion.
Practical Example
Imagine you want to design a simple bracket. Start by sketching the top view of the bracket and then use the Extrude tool to pull it into a 3D shape.1. Sketch a rectangle (20 mm x 10 mm). 2. Select the rectangle and extrude it by 5 mm. 3. Create two holes in the bracket by sketching smaller circles on the rectangle's surface and using the Cut operation to extrude them downwards.
