Discover the process of adding rings on either end of a neck tube in a detailed project using Fusion 360. The walkthrough includes steps for constructing the rings, setting dimensions, and adjusting operations to ensure accurate assembly.
Key Insights
- The construction of rings on a neck tube in Fusion 360 starts with sketch creation, specifically selecting the construction plane called Neck Center, and initiating the line command from the center of the wheel hub.
- Dimensions and degrees are set for each line and point within the project, with the process including switching lines from "Normal" to "Centerline", zooming in to specific areas, creating small rectangles for the rings, and utilizing the perpendicular constraint to maintain alignment.
- After constructing the rings, the Revolve command in the Create menu is used to select profiles and axises, with adjustments being made to the operation of the rings from "Join" to "New Body". Each ring is then named and filleted to add the finishing touches.

Now let's add a couple of rings on either end of our neck tube. To do that, we're going to go back to our Create Sketch, and we're going to select the construction plane that we already created called Neck Center. Next, we'll begin our line command, and we'll start right in the center of our wheel hub.
We'll click one time, and we'll move straight up, and we'll type in our dimension, 110, and we'll click Tab and do 106 for our degrees, and Enter. Now this time, we will select our line, right-click, and switch it from Normal to Centerline. We've got a centerline going up.
Now we'll zoom in to the space between the top of the fork and the bottom of this neck tube, and click the Line tool again. We'll click right here where we left off, and move up and to the right. We're looking for that little perpendicular constraint that looks like a blue square, and we'll type in our dimension.
We're going to go up and to the right, 18, and we'll click Enter. Now we can go and fill in a small rectangle to create our ring. We'll click where we left off, use that perpendicular constraint, and go up, and we'll type in exactly five.
Click the Line command again, click where we left off, go to the left, we'll go exactly six, and click Enter. Now we need one more line. We'll click where we left off, and go straight down with the perpendicular constraint, and we'll type in five.

Now with that, we have this small rectangle here. It is still connected with this full 18 millimeter line, so we will use the Trim command to trim out the extra. And once we have that, we can click Finish Sketch.
Our result is a little rectangle and a center line. We'll go to the Create menu and look for Revolve. We will select our profile, click Select.
It's that small rectangle. Then our axis, we'll click Select, and click on our axis line. The other adjustment we need to make here is our operation.
Right now, Fusion wants to join it to that tube, but this is a separate ring, so we want to swap that from Join over to New Body, and click OK. So there is our ring. We'll look in our Bodies folder here in the Net Component.
We have this generic body now, and we'll call this Ring Lower. And if we have a lower ring, we definitely need an upper ring. So let's go ahead and repeat that process.
We'll zoom out a bit. We'll go to our Create Sketch. We want to select the neck center for our construction plane.
Then we can click our Line command. We'll start right in the center of that wheel hub, click one time, go straight up. This time, we're looking to type in, we've done 110 millimeters to here, and another 110, so it's going to take us to 220.
So 220, hit TAB to lock that in, and our degrees will again be 106,106, and Enter. That takes us to the very top of our tube. Now this line, again, we will select on it, right-click, and change it from a normal to a center line.
So it's a center line. Zoom in, and we're going to create that same little rectangle at the top. We'll use the Line tool, click where we left off, go to the right with the perpendicular constraint, and type in 18 for 18 millimeters.
Click where we left off. Using the perpendicular constraint, we're going to go up approximately or exactly five millimeters, Enter, and then click where we left off. Go to the left this time with a perpendicular constraint, six, Enter, click where we left off, go straight down, type in five, Enter.
And again, use the Trim tool to trim out the extra portion of line. With that, we will click Finish Sketch and go back to the Revolve command. We will select our profile, which is that small rectangle at the top, click our axis selection, select our axis, and our operation will swap out to New Body, and click OK.
Now we have that other body. We'll give it a name, we'll call it Ring Upper. We've got our Ring Lower, Ring Upper, and now we'll add in some fillets to complete these rings.
Up in the Modify menu, we're looking for Fillet, and we'll start with our Ring Lower. We'll click the top line of that ring, click one time, and that edge will get a one millimeter fillet. Now we'll click the plus in our fillet window, there's a little plus to add a selection set, and now we'll click the bottom line, or the bottom edge of that ring, and that one will get a two millimeter fillet.
We have different fillets, top and bottom, and we'll click OK. Let's repeat that process for the top or upper ring. We'll go back to Modify, Fillet.
We will click that top edge, and that top edge this time will be opposite. We'll do two millimeters for the top edge, click Add Selection Set, the little plus icon, click the bottom edge, and that will get a one millimeter fillet, and click OK. Let's zoom out and see our results.
We have now the neck tube, a lower ring at the bottom, and an upper ring.
