Use the coil tool.
00:05
In this video, we’ll create a coil feature and we’ll use a coil to drive a sweep cut.
00:11
In Fusion 360, we want to get started with a new untitled document.
00:16
I'm going to be using a metric document so all of my values will be in millimeters.
00:21
To get started, we want to create a new sketch and I'm going to be using the XY plane.
00:26
Center diameter circle placed at the origin with a diameter of 50 mm and then we'll finish the sketch.
00:34
From here we want to use create extrude and extrude this up a distance of 100 mm.
00:41
We've now created a solid cylinder.
00:44
We're going to explore the coil tool as a use to create physical threads.
00:48
So under the Create drop-down, we're going to navigate down to the area where we have our primitives and select Coil.
00:55
When we create a coil, we first need to select a plane and then we need to draw a center diameter circle.
01:02
Once again, I'm going to draw center diameter circle set to 50 mm.
01:06
Once we do that, you can see a preview on the screen of what's going to be created.
01:11
At this point, we need to begin defining what our coil is going to look like.
01:15
First, we can define it by a specific type.
01:19
By revolutions and height, revolutions and pitch, height and pitch or set it as a spiral.
01:25
We're going to be using revolutions and height.
01:27
The diameter is going to stay 50 mm based on our sketch but we could also modify that.
01:33
We're going to set the number of revolutions at 6.
01:36
Keeping in mind that we don't want to hit the Enter key before we're done entering the values in this dialogue.
01:42
We're going to set the overall height at 95 mm.
01:46
The angle is going to stay zero and we want to change the section from circular to triangular internal.
01:53
From here, we also want to affect the section size.
01:56
Right now it's set to 12.5 mm but we're going to reset this to 5.
02:01
Note that this also can be created as a cut, join, an intersect or a new body or new component.
02:10
We're going to create this as a new body.
02:13
But note that it can be used directly to simply cut or remove material from another solid body.
02:19
We're going to say OK and expand our Bodies folder and rename Body2 to be our Coil Body.
02:27
From here you might be wondering why we're even bothering to create a coil and a cylinder if we simply want to create a thread.
02:35
If we flip the triangular profile around to the external side, we could simply use that as a thread.
02:41
But there are some differences that we want to make sure that we are aware of.
02:45
When we're creating a thread, we need to be mindful of the starting position and its relationship to the solid we're removing it from or adding it to.
02:54
In this case, the coil is going to start if we view this from the right hand side.
02:60
At this position, that's directly centered on our object.
03:04
We might need to create a profile that is not completely in line with our XZ plane.
03:11
We want to make sure that we're aware of this when we begin creating our new part.
03:16
So for now I'm going to hide Body1 and focus my attention just on the coil.
03:21
The first thing that I want to do is go to Construct and create a plane along a path.
03:26
I'm going to select the internal section and I'm going to bring this all the way back down to zero.
03:32
This plane if we view it from the right hand side is different from the external face of our coil.
03:38
This is going to be normal to the direction that we're going to be cutting or removing material.
03:44
So we're going to say, OK, on that new plane.
03:47
The next thing that we want to do is determine what the shape we're going to be removing from our geometry is.
03:54
At this point, we're going to be using our plane to create our profile.
03:57
We're going to be using this inside edge to drive the profile on a sweep and the outside edge as a reference.
04:04
But for now we can hide the coil body and bring back our original body.
04:09
We're going to start a new sketch and notice that the origin point is based on that center point that we use to define the plane.
04:18
So we have this reference and we can determine whether or not we want to simply use a polygon or some other geometry to remove.
04:26
In this case, we're going to use a polygon.
04:29
We're going to start and begin drawing this out.
04:33
And notice that this is creating a polygon with multiple sides.
04:37
In order to create the polygon that we want, let's start the tool again.
04:43
And we're going to go over to this edge number and set it to 3.
04:49
Once we create that edge number, we can begin defining it.
04:53
In this case, we can define it however it needs to be based on our requirements.
04:59
I'm going to use D on the keyboard to set the value.
05:02
And I'm going to begin by setting this to 20 mm.
05:07
I'm going to hit Escape and then I'm going to use horizontal vertical to set this as vertical.
05:13
From here we now have our profile, we have our solid geometry and we have our coil body that will help us drive this cut.
05:21
So from here we can go into our Create menu and select Sweep.
05:25
First we need to determine the specific type of sweep that we want.
05:30
Ours is going to be a path and a guide surface.
05:33
First we select our triangular profile.
05:36
The path is going to be the inside edge of our coil and our guide surface is going to be the outside.
05:42
This is going to allow us to create the sweep that goes along the entire profile.
05:48
Note how it's going around and there are some areas where it's overlapping.
05:51
But because we are removing it, we don't have any problems with the geometry.
05:56
If we were trying to make a solid that had an exact fit here, this might become problematic.
06:02
There are other options that we might want to consider as well.
06:05
There is an analysis section that allows us to analyze the bodies.
06:09
In this case, none can be turned on.
06:11
But we can also use things like zebra stripes or curvature maps or even Iso curves to view what the cut is going to be.
06:18
In our case, I'm going to set this to none and say OK, and allow it to remove that geometry.
06:26
Once we've removed the geometry, we have to be mindful of the fact that what we've actually done is we've removed it from the original body,
06:35
and if we didn't select it, we've also removed it from the coil body and any remnants will be shown.
06:42
This is a very simple example to show you how to use a coil tool and how that can be used to drive custom threads.
06:50
In most cases, a custom thread might have more of a square profile,
06:53
or maybe it's just not a standard pitch that you can find by using the standard tools like hole or thread.
06:59
But if you come across that you can always use coil to create those custom geometries.
07:05
There are some limitations and drawbacks to this tool,
07:08
but often times it will allow you to create that geometry when the hole or the thread tool just doesn't have exactly what you need.
07:15
At this point, let's save this design.
07:18
I'm simply going to call it Coil Thread and then we can move on to the next step.
00:02
Use the coil tool.
00:05
In this video, we’ll create a coil feature and we’ll use a coil to drive a sweep cut.

03:47
The next thing that we want to do is determine what the shape we're going to be removing from our geometry is.
03:54
At this point, we're going to be using our plane to create our profile.
03:57
We're going to be using this inside edge to drive the profile on a sweep and the outside edge as a reference.
04:04
But for now we can hide the coil body and bring back our original body.
04:09
We're going to start a new sketch and notice that the origin point is based on that center point that we use to define the plane.
04:18
So we have this reference and we can determine whether or not we want to simply use a polygon or some other geometry to remove.
04:26
