How to Draw a Circle in Fusion 360

Tinkercad is great when y'all first get-go out in 3D printing but is limited in what information technology tin can do. We bear witness yous how to get started with Fusion 360 instead, and it's also free to use!

3D printing can exist an extremely fun and rewarding hobby. Information technology can teach you a huge amount about manufacturing processes, CNC robotics, fabric sciences, and general engineering. For the nearly part, we all start out merely exclusively trawling Thingiverse for something cool and unique to print. Shortly after, nosotros learn to make small modifications to the things we find on Thingiverse and then offset to brand our own small designs using Tinkercad every bit a starting point.

Before long, nosotros chop-chop acquire the limitations of Tinkercad. Whilst incredible things tin be fabricated with this free online tool, it's a lot more clunky than a particularly designed piece of CAD software.

Over the next few issues, we are going to show you how you can easily brand some of your own designs using Fusion 360.

There are many 3D CAD programs bachelor, nevertheless, we picked Fusion 360 because it is powerful parametric modelling software, which students and hobbyists can become free of charge. This is a very important point because most parametric modelling software are prohibitively expensive, costing several thousands of dollars for a yearly license.

INSTALLING THE SOFTWARE

The kickoff thing we need to do is download the software. Go to https://www.autodesk.com/campaigns/fusion-360-for-hobbyists which will bring yous to the following welcome screen.

Select the 'Get started now' button. This will scroll the folio down showing the post-obit options.

Follow the steps shown ensuring you lot accept your time and read through the folio titled "check your eligibility". If you're eligible to use the software, which we imagine y'all will exist, go along to step 2 and choose the "create business relationship" link.

Fill in the details using a correct electronic mail address and y'all will be bought to the next screen. Alternatively, if y'all already have an Autodesk account from TinkerCad or Eagle, you can employ that business relationship to log in. Only employ the sign in push at the lesser of the folio.

Now information technology's just a matter of installing the software onto your computer, which is done by pressing the become started button.

After installing and running for the starting time time, you will be prompted to verify your electronic mail address. Go to your e-mail client and find the verification email sent from Autodesk. Only press the "Verify Email" link in that email and follow the prompts to login to your new Autodesk business relationship.

You then want to open up the Fusion 360 software on your computer and sign in using the same details.

Later on a modest wait to finalise the install, yous volition be greeted with the following screen showing yous how to admission you preferences, including privacy settings, etc.

That's information technology, you now take a Fusion 360 business relationship and the software installed on your system.

GETTING STARTED

If you await to the right of the main piece of work area, you will see a small dialog box. This box allows y'all to select navigation and view settings based on what you're used to. For instance, if you are familiar with Tinkercad, y'all tin can select information technology from the navigate and view dropdown menu. This will change all of your mouse controls to friction match the controls in Tinkercad. This makes it much easier to navigate. Take note of the settings and familiarise yourself by navigating around the empty work plane in front of you.

Now that y'all have grasped the work plane manipulation, let's move on and start learning how to draw in Fusion 360.

Press the 'Start hither' push if you want to follow some tutorials provided by Fusion 360, or select the shut push button to get drawing.

Note: Nosotros highly recommend you go through the provided tutorials every bit they will undoubtedly teach you some tips and tricks specific to Fusion 360 that nosotros may not comprehend over the next few issues.

Get Cartoon

For our very first project, we are going to offset with something nice and simple, only to get ourselves comfy with the Fusion 360 interface.

A useful tool for newcomers to 3D CAD blueprint is a circular gauge (also known as a Radius Gauge). This is a basic tool a 3D modeller can use to easily measure the curvature of an item you are modelling. Allow'south say, for example, you desire to make a comprehend for your mobile phone.

There are a number of rounded corners and rounded edges on modernistic phones. It would be very time consuming and difficult to physically calculate the geometry for each of these rounded edges, so for quick jobs, it'south often much more convenient to have a circular gauge. You but put the judge against a rounded object to decide the radius.

Y'all volition certainly observe this gauge useful as you kickoff to model real-earth objects. It'due south elementary all the same detailed design makes information technology the perfect candidate for our first ever Fusion 360 project.

To become started, take a look at the drawing on the opposite folio to requite you the basic idea of what we are going to draw in Fusion 360.

The first matter we demand to do in Fusion 360 is set the perspective. Since we volition starting time by drawing a simple 2D shape and extruding it from a single plane, we observe it best to work from the top-down perspective.

To alter to this top-down perspective, mouse over to the perspective box in the height correct corner of the work plane. Left click the word 'peak' on this cube and your perspective will change to this plane.

From hither, we want to start drawing the features of the round gauge.

Select the 'Sketch' button in the top left carte du jour and then select the blue foursquare that appears on the work plane. This square sets the origin to the plane, which means in what infinite we are drawing X, Y or Z.

To start cartoon, press the 'C' key on your keyboard. This will select the circle drawing tool. Left-click once anywhere in the work plane and you volition brainstorm to draw a circle. From this point, you can only enter the required diameter of the circle.

Our drawing shows the curved edge on the right side of the gauge has a radius of 8. We need to multiply that value by 2 to get the diameter. Enter 16 on your keyboard and press Enter.

You should now accept a perfect 2nd circumvolve, which you lot can place on the work plane. You tin click and concur the heart point of this circle and drag it effectually the piece of work plane to position it where you desire.

Looking at the drawing in a higher place, we know that the contrary side is as well constructed with a circle with a radius of 22.1, giving it a diameter of 44.2.

Repeat the previous steps and create a second circle with this diameter and identify it to the left of the first circle.

Your drawing should wait something like this. Annotation that at this point, we can move both circles around equally there is no relationship betwixt the ii objects. To fix this, we want to create a straight line between the height of the ii circles 126.35mm long. To do that, use the line tool by pressing 'L' on your keyboard, and depict a directly tangental line across the top with a distance of 126.35mm.

In the sketch palette on the right of the piece of work airplane, you will see some constraint options. These options allow you to ascertain the relationship betwixt features in your drawing. In this case, we want the line nosotros only drew to be a tangent to the two circles. Select 'Tangent' and then select each of the circles. This will force the circles to marshal tangental to the 126.35mm line joining them.

Select the 'Ancillary' button, select the circles, which volition brand them both tangent and coincident to the 126.35mm line, firmly locking them all together.

Notation: Afterwards doing this, the objects will turn blackness signifying they are fully constrained, and yous will exist unable to move them. This is ideal equally these tin can not be changed by later actions.

The final step to finishing the outline is to describe a line connecting the bottom of each circle. Only printing the 'L' key on your keyboard and draw a line betwixt the ii circles. Use the tangent and coincident constraints to lock this line to the existing features. When yous're washed, the sketch should become shaded and the lines should all be black indicating they are fully constrained.

Now we want to add together the 11mm radius on the left of the shape. To do this, practise the aforementioned equally previous and press 'C' on your keyboard, and then enter the dimensions. Nosotros desire the diameter now, so its diameter = 2 (radius) or ii x 11 = 22mm diameter.

Once the circle has been placed, press 'D' on your keyboard to bring upwardly the dimension tool. Select the centre point of the circumvolve we but added, and so the connecting point betwixt the top line and left circumvolve equally shown below.

We desire this altitude to be 13mm, every bit the diagram shows that the start of the R11 is 2mm from the tangent junction. We also desire this to only protrude ½ (radius) into the existing shape. Therefore, use the 'D' fundamental on your keyboard to select the dimensioning tool. Set the altitude from centre point of the circumvolve to the top line to one half of the radius as shown.

The cartoon should now look similar this.

You desire to repeat the same process for the remaining viii radius features on the top line. Keeping in mind, the radius is ½ diameter and the depth is ½ radius. Too, note that each feature is separated by 2mm.

TIP: In Fusion 360, while inbound the dimensions you lot tin enter mathematical operations.

To get the altitude betwixt the two circles we used the line tool '50' on the keyboard to measure the distance betwixt the two features. Yous then simply adapt the distance between the 2 centres until the distance = two.

For instance, if the distance betwixt the centres of the 2 features is 23, and the measured gap between them using the line tool was 4.5, yous would just make the distance between them (23 -ii.5). This would adjust the gap to 2mm.

When yous're done adding all of the height radii, it should expect like this.

We take added the dimensions here to brand the distance between circumvolve centres easier. In item, note that the results are an estimate and more than than good enough for the purpose of this exercise.

We now want to add the final radius to the bottom side. Follow the aforementioned steps equally the previous, noting that the radius starts at the tangent bespeak of the 44.2mm outer circle and the bottom line.

One time you take drawn this, y'all want to too add a 4mm circle in the 44.2mm end. This will form a pigsty to allow us to hang the gauge off or connect a key band. It isn't of import where we place this, just brand sure it's close to the edge if you want to attach a ring to it.

When y'all're happy with all of the dimensions, choose the 'Select' button from the bill of fare. While holding downward the CTRL key on your keyboard select the sections you desire to extrude. When done, it should look like this.

Press 'Q ' on your keyboard to enter the printing pull tool, which will bring up the following options.

Nosotros want to extrude this to 4mm to match the provided drawing. This will force all of the shaded blue areas to become a solid object with a thickness of 4mm. In the distance section, enter 4mm and select OK.

With the 2D model now a 3D model, nosotros are able to start adding some of the details such equally the chamfers and number indicators.

Allow'due south start by first placing the numbers. Nosotros didn't add together their positions to the drawing equally it isn't overly important where they are placed, provided of course, information technology hands shows which radius information technology is referring to.

To go started, select the top face up of the 3D model. In the menu, select the dropdown arrow on the sketch push button. Move your mouse over the Text pick and left click. Move your mouse to where y'all want to place your text and left click. This will bring upwardly the text placement card. Here you can enter the text you lot desire to display, set the size of the text and its angle.

We went with 4mm text. Any smaller and it would be hard to print clearly, and much higher will reduce our room to sketch in the logo or picture, etc. If y'all're going to do the DIYODE logo we recommend yous continue it at 4, yet, if you lot're putting anything else, it volition depend on the room yous have left.

You want to repeat the process for all 10 of the different radii.

With all ten numbers added and in place, printing 'Q' on your keyboard to enter the 'Push Pull' part. Hold downwards Ctrl and manually select each of the numbers. This will bring upward the following extrude carte du jour.

Prepare the distance to -0.v to extrude a void into the surface of the model one-half a millimetre and printing OK.

If you change the perspective, you will see the now indented numbers on the surface of the model, as shown below.

Next, we desire to add some chamfers to the edges. This will give the model a much more finished appearance.

We are going to requite every lesser surface a 1mm chamfer and repeat on the top with the exception of the radii edges. We want them as sharp as possible to help in gauging.

To add the chamfer select the modify dropdown arrow and select Chamfer. This will open the menu options shown to a higher place. Concur down Ctrl and select the border of each surface, excluding the top side radii. When you release Ctrl, the program volition automatically chamfer the edges equally per the value in the distance dropdown. When you have chamfered the desired edges by 1mm select OK.

The final stride is to add together the DIYODE logo or your ain. A suitable DIYODE logo is available in the Resource section below.

The easiest way to do this is to import an image and just trace around it. Naturally, the improve the quality of paradigm the easier this volition be. Of course, yous need to physically trace every edge so extrude it and then this shouldn't be washed with loftier particular images. There are ways to import .SVG files, which are vector files. Withal, this requires other software and is outside the scope of a bones introduction to Fusion 360.

To bring an paradigm into Fusion 360, but select the Insert icon, which will open the fastened canvas dialog box. Select the epitome y'all wish to import, then select the surface y'all want the image placed. We are going to go far on the superlative surface of the round estimate, so select that surface.

This will import the paradigm in full size. To drop the size down, in the calibration x and y boxes, we desire to enter 0.iv. Make sure you lot do the same value in both, otherwise the ratios will exist changed. As well, brand certain the Display Through box is left unchecked, otherwise you won't be able to see the image when we start tracing.

Once you have scaled information technology to the size you want click-and-drag the image to place in where you want information technology. When you're happy with its positioning but choose OK.

Select the top face of the model and press 'L' on your keyboard to select the line tool. The vast majority of our logo is straight lines so we can, for the well-nigh part, utilise the line tool. If your epitome is fully made of organic shapes, skip ahead to the spline tool section.

Yous want to trace around each of the straight lines of the letters in the logo using the line tool. Ignore the curved sections of the O and D's for now, we will use the spline tool for them.

We find it's a adept idea to first practise the top and bottom lines. These can be used to define the edges of each letter.

When all the straight lines are traced, select the sketch dropdown pointer in the carte du jour and select the control point spline tool. This tool will smoothen out the line your drawing and the more points of reference y'all give it the smoother the line. Select one of the line ends you made previously, and whilst zoomed in, advisedly select the border of the paradigm following the curvature until you encounter the adjacent line finish. Yous simply double-click the end of the meeting line and the spline tool volition create a smooth curvature for yous.

Precision is non overly of import for this logo, the slicing and printing operation will unremarkably remove any small inconsistencies, and as such, provided the spline tool follows the aforementioned full general shape you will be fine. Nevertheless, if you're printing fully organic shapes yous will want to accept your time with the spline tool.

After you have traced effectually the logo it should look like to this.

Simply similar with the text earlier, we want to extrude this logo as a hollow. Except, in this example, the logo is sitting apartment on the work airplane surface. As such, we want to include a 3.5mm offset to have it start at this signal and extrude out 0.6mm so it clears the model surface.

To exercise this, printing 'Q' on your keyboard to enter the Press-pull procedure. While holding Ctrl, select each letter of the logo you lot wish to extrude. Note you may need to change the view so you're looking at the logo from beneath.

Once you have done that, your starting time ever Fusion 360 3D object is complete!

All we need to do now is consign the file as an .stl and then we can print it. Select the 'Brand' push, which will bring up the 3D print bill of fare.

You lot want to select the model and uncheck the "Send to 3D Print Utility" box. The model volition turn blueish and show the triangulation wireframe. Y'all can change the refinement if you like, notwithstanding, nosotros find we just tend to gear up it to high for every print.

When you lot're happy, press OK and choose where to save the file and what proper name to requite it. You can now add together this file into your Slicer and impress it equally normal.

The skills shown in this tutorial are just the basic cartoon and extruding tools yous will need to get started with Fusion 360. Yet, the only mode to get confident with something is to keep at information technology.

Yous can keep the momentum going and modify the gauge, try making it in 0.5mm increments, for instance, 3.5mm radius to 12.5mm. The more you apply the software the more comfy yous will become with it.
