Sandy Ganz shared these photos of a custom clock he's building. This 42 inch wide custom faceplate was waterjet cut by Big Blue Saw from aluminum 6061. The plan is to install old-school incandescent bulbs in a classic 7 segment display.

Michael Backus of Lightning Rods wrote in to show us some of the parts he made for performance electric vehicles.

I design and build electric bike conversions. [...] Your web site is incredible. Whatever it cost, it was well worth it.

I'm attaching a few photos of electric drives I've done since I started using your services. I'm very, very happy with every aspect of working with you. You'll be seeing much more of me in the future!

UPDATE: there's another technique for creating parts with Big Blue Saw and Fusion 360 that you may find helpful. Check out Update For Fusion 360 Users: STEP File Compatibility first!

You may have seen our earlier article on turning your Fusion 360 design into a real part using Big Blue Saw. As soon as that article was published, all the Fusion 360 fans out there let us know that there is a much easier way to get the job done. 

Based on a recent informal survey, Fusion 360 is very popular among both our professional and hobbyist clients. Hobbyists love that it's  free for personal use, and pros dig the expansive power of its built in tools for PCB design, sculpting, and generative design. After you've created your design with Fusion 360, how do you turn those designs into real parts made from aluminum, polycarbonate plastic, or another material? That's what this tutorial is about.

(Note: as I was creating this tutorial, Autodesk changed the terms of use for Fusion 360 in the hobbyist edition. Fortunately the techniques described here should still work with the free hobbyist license.)

In this tutorial, we'll look at two different procedures for making a DXF file for use with Big Blue Saw's online ordering system. The simplest procedure applies if you already have a sketch in the part design with the complete outline of the part. If you don't have a sketch with the outline of the complete part, there's easy procedure you can follow to get a clean DXF file.

If You Already Have A Sketch

Below is a bracket design, the type of part we make every day here at Big Blue Saw.

Note that this part is an extrusion of a single sketch. You can click the sketch in the browser to see it highlighted in the main view of the part.

Right clicking on the sketch should give you a menu with the option to save the sketch as a DXF. Very conventiently, the DXFs that Fusion 360 makes are scaled 1:1 with no extraneous lines, formatting, or other marks. This is exactly what we need for Big Blue Saw's online quoting system. Thanks Fusion developers!


When you click Save as DXF,  the save dialog will appear. Choose a filename for the DXF export that you'll remember, and don't forget to note which folder you saved it in.

Now you can upload the design to Big Blue Saw's website for an instant quote and online ordering!


If You Don't Have a Sketch

Now let's take a look at a different part. This is also the type of thing we make every day here at Big Blue Saw.

But the way it's designed in Fusion 360 is a little different. In this case, the part is designed by combining several sketches as well as using the Hole and FIllet tools to make features on the finished part. We don't have a single sketch with just the outline of the piece. Another way you might find youself in this situation (not having a single sketch) is if you import a design from another CAD program.

We can verify that the sketch doesn't outline the entire part. By clicking on one of the sketches in the browser, you can see that it's just the design for the tab on the left.

We'll need to make a new sketch that can be exported as a DXF file.  Fusion 360 makes this easy. Right click on the top face of the part to show the context menu and click Create Sketch.

This will make a new sketch and put Fusion into sketch mode. The features of the part are automatically projected into the new sketch.

Click the Finish Sketch button on the toolbar to get out of sketch mode.

Your new sketch will appear in the browser.

Right click the new sketch and pick Save as DXF.

UPDATE: there's a much easier way to do this than is shown in this article. Check out Fusion 360 Custom Parts the Easier Way first!

Fusion 360 from Autodesk is one of the most popular 3D design and modeling packages available today. A recent poll of Big Blue Saw's customers showed us that it's the 2nd most used CAD package, just behind SolidWorks. It's free for personal use, which makes it very easy to get started.

But once you have created a design in Fusion 360, how can you turn that digital file into a real part from Big Blue Saw made of aluminum, stainless steel, or another material? Let's take a look.

For this tutorial, we're going to begin by assuming that you have some experience designing parts in Fusion 360. Below is a typical bracket created in Fusion 360, the type of part that we create every day here at Big Blue Saw.


With your design open, click the File icon and pick New Drawing | From Design in the drop down menu.


This will pop up the Create Drawing dialog. The default options shown below should work for your part. In particular you want the Template option to be "From Scratch". The Sheet Size should be large enough to fit the entire part. In this case, we know that the part is 12.475 x 6 inches, so size "B (17in x 11in)" should be plenty. Click OK to accept these options and close the dialog box.


Next, the Drawing View dialog will appear. You'll need to pick an orientation such that you can see the entire outline of the part. In this case, the "Top" orientation allows us to view the part's outline. If you choose the wrong orientation, you'll see the part edge-on, which won't give enough information to the online quoting system to make the part.


Choose the "Visible Edges" setting for the Style to create a drawing that only shows the top face of the part. Again, we don't need hidden lines or shading; the goal is to create a drawing with just the outline of the part to be cut.


Next, set the scale to 1:1 by entering "1:1" in the Scale field. This saves us from having to rescale the design after uploading to Big Blue Saw's online quoting and ordering system.


Now you should be able to click in the drawing area of the window to place the outline. As long as it's somewhere in the middle, you're OK.


Click the OK button on the Drawing View dialog.


Fusion 360 should show you a drawing like the one below.


Again, our goal here is to eliminate everything but the outline of the outline of the part. Click the drawing details to select them and press the Delete key to get rid of them.


There's still a drawing border left. Click anywhere on that and press Delete on your keyboard to get rid of that as well.


You should now have a drawing, scaled 1:1, containing just the outline of the part to cut.


Next, we should save the drawing for later access. If we update the part model, this drawing will update automatically. From the menu, choose File | Save or press Ctrl-S.


The Save dialog will prompt you for a name for the file. Choose a name wisely so that you can remember it later. Click the Save button when done.


We're in the home stretch here, and ready to save a DXF file for Big Blue Saw's online quoting system. From the toolbar, click on the Output button and choose Output Sheet as DXF from the drop down menu.


A save dialog will appear which lets you save the DXF file anywhere on your computer. Be sure to choose a memorable name for the file and remember what directory you saved it to.


The DXF drawing file can be uploaded to Big Blue Saw's online quoting system for an instant quote.
