- [Narrator] Often in SolidWorks,
we want to take existing geometry that we already have,
such as a sketch, and copy it over
to different regions inside the model
so that we can reuse it.
In this model right here, I've got a cutout
that's a particular shape on the side of this part.
And if I just click on the sketch,
hit Control + C, and then Control + V,
I can copy this sketch over to this other part of the part.
Now, let's say I want to modify this whole sketch.
I want to scale it up and move it a little bit.
That's where the Modify tool comes in.
We go to Sketch Tools and down to Modify.
But you have to make sure you're
in the sketch that you want to edit,
so I'm going to edit that sketch and go back
to Tools, Sketch Tools, and Modify,
and now you see we get this new window that shows up.
And it's pretty straightforward.
Basically what you do is you use
these indicators as your center point,
and that's where you're moving everything along,
so that's your origin for this sketch.
You can also have a movable origin
that you can drag and move to different points,
if you want to have it to that center, or to the top,
or over here, I'm simply using
my left mouse button, held down, to drag that around.
But otherwise, I can just use the sketch origin.
We can scale it by different factors,
so if I want to go twice as big, I can scale it up.
I'm going to it back down, 0.5.
We can translate it and move it in a different position,
so if I want to scooch it over just a little bit,
I can do that, move it up.
Now every time I add one of these values and hit Enter,
it's changing the value but if I go to the value
and hit it again, it'll repeat the move.
So you're not just moving it to that value,
you're moving it by that value.
And it's the same thing with the scaling factor
and the rotation, so if I rotate this by 90 degrees
and hit Enter, it's going to rotate.
If I then hit 30 and hit Enter, it's going to rotate
by another 30 degrees, not at 30 degrees.
So that's important to note, that once you make these moves,
you can't exactly go back inside of this,
you'll have to restart the Modify Sketch feature.
You can hit close, and just hit Control + Z
if you want to undo the move, but it's easier
if you know exactly what you want to do,
you can just go right back into Sketch Tools, Modify,
and move it over a little bit,
so I'm going to go that 1/4 inch in the X
and then a 1/4 inch in the Y, and I'm going to
scale it up just a little bit.
And then I'm going to hit close, and now I can use this
to make another cut in a different region of the part.
So that's how we use our Modify tool for sketches.
