- [Instructor] A sketch bend allows you
to take an existing part
and then just creating a couple of sketches,
create individual bends based upon where those lines
are added to your part.
This is great for imported geometry.
Or if you're starting from a part
that was originally not a sheet metal part
and you're converting it over to sheet metal
and you wanna add in these bends,
this is a great way to do it.
So all we need to do is start on the top face.
Start a sketch.
And let's go ahead and just use a regular line.
I'm gonna snap from that edge there
and just go across the part.
Now you have the ability to kinda just snap over here,
but it doesn't really actually matter how long the line is.
Click on Dimension.
Let's dimension that to the end of the part.
Let's type in .75.
And there is our sketch bend.
I'm gonna exit outta that.
And we have that sketch highlighted.
Now come over here to Sheet Metal
and click on Sketched Bend.
Alright?
My first question I'm asked here
is what is gonna be the flat face.
I'm gonna choose this one here.
And it gives you a nice preview
of what's gonna be happening.
I'm actually gonna flip that around
so it goes the other direction
by clicking on this little arrow here.
We do want a 90 degree bend,
and we can also choose where the bend position is.
Right now it's right at that line.
I could also push the material to the inside,
to the outside, or actually the entire bend to the outside,
just like we can on a regular edge flange.
But in this case let's go ahead
and just use that center line, or that bend center line.
There it is.
Click on Okay.
And there's my very first sketch bend.
Now I can continue on with my part.
In this case here I'm gonna choose one more sketch.
Start a sketch here.
And I'm gonna create a line starting at the end
of this radius here.
I'm gonna make it only go a short distance.
I'm not gonna go all the way across the part.
Ideally I'd probably snap it there
or I could actually make it go further,
it doesn't matter.
But in this case I'm gonna make it just
a very short little line,
showing that it works both ways.
Alright?
Exit outta that sketch.
So there's my line I wanna be using.
And here's my sketch bend.
I'm gonna choose this as my flat face.
Notice it gives me a nice preview of what's gonna happen.
It's gonna be bending that up,
doing it right at that center line is just fine with me.
90 degrees looks good.
If you wanted to, of course, you could change
your Custom Bend Allowance,
but in this case the standard is fine.
So click on Okay,
and there you have it.
So sketch bends are a great easy way to add bends
to a part defined by a sketch,
not by actually creating an edge flange.
Or if you already have some existing geometry,
you just wanna add a couple bend in here,
it's a great way to do it.
And it's, again, very easy.
All you need to do is start a sketch,
place a line where you'd like to place a bend,
and then create that bend.
