So we've had a look at trimming and extending.
The next thing really to move on to is the fillets and the chamfers, which can be found under this
Modify panel.
And if you pull down this arrow, you get fillet, chamfer and blend curves.
So let's just have a quick run through those and see what they actually do.
And we'll start with fill it so you can kind of see and get an idea based on just the icons here.
Affiliate will take two lines and put a curve radius curved between them.
A chamfer will put a 45 degree line.
It doesn't have to be 45 degrees, but it will put a line, a straight line between them like that.
And blend curve will take two curved lines and create a nice smooth curve between them.
Okay, so let's look at them all in action.
We'll start with affiliate command.
So first I'm just going to draw a couple of lines.
I'll make these.
Let's make them to 50.
Okay.
I'll put one there and I'll put one.
So let's say you've drawn this, okay?
And you've got two lines like that and you decide you want these to be you want a curved corner on here.
Okay.
Now we've drawn this line is 250 long, so probably you might want a 50 radius.
And again, we're working in units.
Now, this kind of these basic lessons, we don't necessarily need to be in millimeters or inches.
We're not creating anything real.
So I'm just going to I'm just going to say units and that covers everything.
Okay.
So if that's 250 units long, then let's try a 50 unit radius curve on there and see what it looks like.
So the way we would do that, we would go up to fill it.
Okay.
And it's going to ask you for two objects.
Okay.
If I was to just select one two, you'll see what it's actually done is it's created a right angle corner.
And we said we wanted a 50 radius.
Okay, well, you need to actually tell it the radius.
But if you don't, it defaults at zero or it actually defaults to the last radius you use.
So if it's something you've command you've done before in that drawing, it will just use the previous
radius.
If it's a new drawing such as this one, it will default to zero.
But sometimes you actually want that.
It's a good way to join two lines.
If you wanted these to be a corner rather than kind of trying to trim, extend, trim, extend, you
can just go fill it, okay.
And then set the radius to zero.
And the way you change the radius, you can see down here, as usual, we've got some options and we
have radius.
You can either left click radius or you can see it's got the highlighted R at the start.
You could type in R return.
Okay.
But the easiest thing these days is just to click and you'll see it says specify fillet radius and this
is the default that it's set at now.
So if we leave that, if we so if we left it at zero.
Okay, we can press return or right click because our mouse is set up that way.
Now we just need to select two lines and we can select our two lines and it will do that radius for
us there.
Okay.
Now, supposing we've done that and we decide we want this 50 unit radius.
We can select radius and now we'll type in 50.
Okay.
And either enter or right click.
Now, when we pick the lines again, it doesn't matter which two lines you pick which way round, but
you'll see it gives us this nice smooth radius.
And because we use Polylines, it's also turned it into one polyline.
Okay, so that's a good way of doing curved corners.
Now, supposing you wanted kind of a straight line chamfer.
We'll have a look at that and we'll go to Chamfer and you get some options again here.
Okay, So you need a few more.
You need more than just a radius on this one.
You're going to have a straight line between these two creating the corner.
But that line.
So you need to know what angle that line is.
Is it 45 degrees or is it going to be?
Start back here and be quite.
Kind of a shallow angle.
It's in the other way up there, so you need to tell it basically three things.
It wants to know the angle.
But even if it knows the angle, it doesn't know where to start.
A 45 degree angle could be here.
It could be here or it could be back here.
So you also need to tell it the distance back.
From the corner.
If it was a right angle corner, the distance back where it will start.
We'll have a look at those options.
So let's look at those and let's see what it asks for.
So we have a few options.
We can say distance, angle, trim.
Most of the time you'll be working with an angle, you'll know the angle.
Okay, So if we click on Angle, it's going to say, okay, well what's the length on the first line,
the chamfer length?
And that basically means the, the length.
If this is the first line, the distance back from if it were a right angle, corner will be.
So we'll say let's go with 100.
Okay.
And now it will say, what's the angle from the first line?
And we're going to put in 45.
Okay.
Now let's say select first line.
Select second line.
And that's given us a 45 degree angle.
That and this distance here will be 100 and that will be 100.
Now, I'm going to do that again.
And this time I'm going to say distance 100 again.
But now the chamfer angle from the first line, I'm going to say it's 25 degrees.
Okay.
So this time it now it does matter which line we pick first because.
If I.
If I put that line first, you'll see we get a greater angle here.
So when I said 25 degrees, it was from.
This first line, if that makes sense.
If I was to do exactly the same.
Go to angle distance 100.
Angle 25 degrees.
But this time I pick this as the first line.
You get the angle in the opposite sense because it's it's taking 100 and the 25 on this line.
Okay.
So hopefully that makes sense.
We're going to use these in practice.
So will become will make more sense but that's chamfer again have a play about with it.
Have a play with some of these you can you can set it just by distance.
Okay but the main way you would use that is by angle and then it will ask you the distance of a first
line.
So have a play about with that and get used to using it.
But next one, I'm going to do a polyline and I'm going to do an arc by pressing a let's just turn off
or off and what I'm going to do, I'm going to drag that there, okay?
And I'm going to copy it.
And rotate it.
So if you're following along with this, you don't need to be doing exactly the same as we just put
two arcs, which would be kind of difficult to just if you want to join that end.
To that end, it's not a simple case of just extending or anything or trimming.
It needs quite a complex curve to do that.
So we're going to use that as the example for this blend curves.
Okay, we're going to click that and now it's literally just select the first curve, the next one,
and you'll see it.
It works out some kind of curve.
If we undo that and have a look at our options, we get continuity.
Okay.
So do you want it tangential or smooth?
That was tangential.
That was the default.
Let's try a smooth one.
Pretty much the same thing.
Okay.
Now, if you click these, you get some options.
So you can you can set it to fit, which will be kind of an automated smooth fit.
Or you can have these control vertices.
Now, control vertices will let you pick these vertices and drag them about.
So it allows you to edit the way it's developed that curve.
Okay.
And it gives you a bit of control.
So it's for blend curves command.
Again, it's one of those hardly ever used.
But then when you do need it, it's very useful.
The fillet and chamfers I use a lot, especially fillet.
Yeah, I'll do fill it.
More of an chamfer.
Um, but it would depend what you're doing.
But fill.
It's definitely use a lot for doing rounded corners.
Yeah.
Fill.
So that's it.
That's fill its chamfers and blended curves.
And if you have a play about them maybe rewatch it.
If you didn't quite grasp some of the options once you get used to using these, it's just second nature.
The main thing you do is just fill it, select your radius and go ahead and do your rounded corner.
Okay, so let's fill it and chamfers.
