- [Instructor] I'm going to talk about sweeps now.
I'm going to use the sheet metal bracket reference file
that you downloaded at the beginning of this tutorial.
I'm go ahead and hide the green sketch.
Select on my sweep function.
What I want you to notice within sweep,
is you have several profile types.
The sweep operator is genuinely massive
as far as its capabilities.
This is just a basic introduction into the surfacing.
The two types of sweeps I do want to talk about
are two of the most commonly used.
The first one is a line type sweep with draft direction.
The second is a circle type sweep with center and radius.
We'll go in with line sweep.
The way this works is you specify a guide curve.
Then, you specify a draft direction.
In this case, I'm just simply going to use my xy plane.
We'll specify xy plane out of the tree.
What this does is it sets up a vector direction
that an angle is going to be measured from
and also the direction that the sweep is going to travel
as far as the length of.
By default we have zero degrees
and we have a 20 milometer length.
I'm just going to increase that length for now.
Let me shrink the menu just a little bit.
I'm going to preview.
Currently, I'm going zero degrees, and it's 54 milometers.
You can see I have two arrows.
This is the direction that this sweep is going in.
As soon as I increase the angle,
you'll notice that the two become four.
There are basically four quadrants,
based off of the vector direction.
Do you want it to go this way,
this way, this way, or this way?
In this case, I'm going to select this up arrow, pointing away.
And preview.
Now, that line shape
is being swept around this guide curve.
With the profile type set to line,
basically you're drawing a line.
That line is measuring an angle of 17 degrees.
That 17 degrees is based off of my vector direction.
It is going to be 54 milometers long.
I can can go in both directions if I want to.
I can increase the length
going downwards as well.
And again, I can specify
any direction that I want this to go into.
That's a line sweep using a draft direction.
This is going to be very important for parts
that need to be released out of a tool,
like an injection molded part
or a part that's a casting, die casting,
whatever that may be.
Drafts are very important for manufacturing purposes.
There's my sweep.
I'm just going to hide that.
I'm going to go back into sweep.
This time I'm going to go into circle.
Again, under circle you have several subtypes.
I'm just going to do center and radius.
The way this works is you simply specify a center curve.
Enter in the radius value, and preview.
In this case,
I don't have to draw a circle to sweep along that profile.
This can make cable routings, tubing routings.
Whatever it is, specify the radius value,
pick the center curve,
and let the sweep do the rest of the work for you.
Again, very powerful.
Select OK.
I'm going to go ahead and hide that.
I'm going to go into--
Let me go ahead and hide this sketch,
and show the main body sketch.
I'm going to perform another sweep.
You'll notice that if I pick a sketch
that has corners in it,
put in my radius value, preview,
it actually puts in those corners into the sweep as well.
A lot of times if you're creating, let's say a chassis,
and you're going to be using cut and welded tube,
you can just basically draw the profile,
put in the tube size, done.
Creates the corners for you nice and clean.
Let me go ahead and hide that.
Go back into sweep.
Once again, I'm just going to go into line type
with draft direction, pick my guide curve,
draft direction, in this case.
If I look at my compass, you can yz.
Pick my yz plane.
Again, specify the angle, preview.
I can use guide curves that have corners.
They don't have to be perfectly smooth to create my sweeps.
