How to Cut Letters in Fusion 360

Creating letters with precise cuts in Autodesk Fusion 360 can enhance your design projects, whether for laser cutting or 3D printing. This guide will walk you through the steps to achieve cleanly cut letters using Fusion 360.

Setting Up Your Workspace

Start by launching Fusion 360 and creating a new design. It is important to set the workspace properly before beginning your lettering project.

1. Open Fusion 360 and select File > New Design.
2. In the browser, right-click on Components and choose to create a new component, naming it appropriately for your project.
3. Adjust the view by selecting Top View from the view cube in the upper left corner for better visibility while you work on the sketch.

Creating the Text

The first step to cutting letters is to create the text you wish to work with.

1. Click on the Sketch menu and then choose Create Sketch.
2. Select the plane where you want to create your text (typically the XY plane).
3. Find the Text tool in the Sketch menu. Click on it to open the text input window.
4. Type your desired letters into the text box. You can also adjust font style, size, and orientation.
5. Click to place the text on the sketch plane. Use the pink handles to adjust its size or move it into position if needed.

Finishing the Sketch

Before you can turn your text into a solid cut, it’s essential to finalize the sketch.

1. Once your text is positioned correctly, click on Finish Sketch in the toolbar.
2. With the sketch visible, go to your Solid tab and select Extrude to create a 3D shape from your 2D sketch.
3. Select the text you created, and choose the direction and distance for your extrusion. Ensure the end result is in line with what you’re aiming to achieve (typically a thin sheet or surface if cutting).
4. Hit OK to apply the extrusion.

Preparing to Cut

The next phase involves preparing your letters to be cut from your model.

1. You can create a new sketch on top of the extrusion or select Create Sketch again to work directly on the surface.
2. Use the Project/Include tool to project your text onto the new sketch. This action transfers the outline of the text as a series of lines and curves that can be used for cutting.
3. Verify the projection by finishing the sketch, ensuring everything looks correct.

Defining the Cut

Now that the lettering is prepared, it’s time to define how these letters will be cut.

1. With your projected sketch selected, go back to the Solid tab and choose Extrude again.
2. For the operation type, select Cut to denote that you are removing material.
3. Define the depth of the cut. You may either specify a distance or use To Object if you want the letters to cut through the entire thickness of your design.
4. Review the cut preview to ensure everything is positioned correctly, then confirm by clicking OK.

Saving and Exporting Your Design

After finalizing your cut letters, save and export your work for printing or cutting.

1. Click on File > Save to ensure all of your changes are saved in the Fusion 360 environment.
2. To export your design, select File > Export and choose the appropriate file format (such as DXF for laser cutting).
3. Follow the prompts to select your export options and designate where to save the file on your computer.

Frequently Asked Questions

What types of fonts can I use in Fusion 360?
Fusion 360 supports most standard fonts installed on your computer. However, font rendering may vary, so it’s best to test a few before finalizing your design.

Can I create more intricate designs beyond simple letters?
Yes, Fusion 360 allows for complex designs. Use additional sketching tools like lines, arcs, and circles to create detailed shapes and incorporate these into your cuts.

What if I want to change my text after creating the sketch?
If changes are needed, right-click on the sketch in the browser panel and select Edit Sketch. This allows you to modify the text directly without starting over.
