- [Instructor] Sometimes it could be advantageous
to use the pattern features inside of your sketch
instead of using the feature pattern
after the fact to create cuts in something
or if you're trying to make a mesh- for example
- like material or any other kind of pattern.
Let's run through the two patterns
that are available to us in Sketch.
So, here we've got Linear Sketch Pattern.
If I click on the dropdown we've
also got Circular Sketch Pattern.
If we hover over this for a moment,
I'm just going to dropdown and come back,
we can see that it says it adds a linear pattern
of a sketch entity, pretty simple.
I'm going to click on that, and you can see here
in our property manager that we've got a bunch of options.
Basically, what it wants is your x and y changes,
so what distance and how many times you want to pattern
your object, and if you want to do it at an angle.
Same in the y direction, it prompts you
to select your entities, so I'm going to select
on this window so it highlights red.
Select this sketch entity and this sketch entity,
you see the two arcs show up, and now I'm going to
go up here and adjust how they pattern,
so I'm going to give them each a one-inch pattern,
and I have to increase this to two to active it.
I'm going to give this a one-inch pattern,
and I can see that's not enough, so let's go by 100.
Too much, how about 15, there we go.
We can see that now, we'll go a little bigger than that.
All right, and we'll do the same with this one.
Now, you could see it gives you a preview of your pattern.
Now, I'm doing a two by two right now,
so it's patterning each of these twice
in the x and then twice in the y.
I can grow these by simply clicking up
the number of units here, and you can see
the pattern trickles out in both directions.
(clicks)
Now, if there's any instances in this pattern
that I want to skip I can go down here,
click on here, the dropdown, click on Instances to Skip,
and then if you hover over the purple points
you can click on them to begin skipping
instances that you don't want to pattern
and it collects them down here,
and then if you want to add them back in
you just simply delete them or you can clear the selection.
I hit Okay and my pattern is created.
Now, if you want to edit the pattern
this is kind of a funny thing.
You see this seven and two right here?
That's indicating that you're going
two pattern this way and seven patterns up.
If I click on any of the items in the pattern
you'll see this pattern feature
here in the Existing Relations.
If you right click on that you
can go in and edit the pattern.
There's not going to be anything in your Feature Tree
that says "pattern" or anything like that,
so that's the only way that you're going to be able to edit it,
and also, something to consider, too,
is once you make the pattern it doesn't necessarily
maintain that pattern that you originally set.
You can click and drag the items that you've patterned,
and depending on how you did it, they'll adjust.
So, these aren't, you know, fixed in space.
You know, I can click and drag the items,
and because of the specific relations that it has
it's moving in this kind of way,
but sometimes it won't, you know, move like that at all.
I can just grab a single point and move it out,
rotate it, do all kinds of stuff.
So, that's doing a linear pattern.
Now, let's take a look at a circular pattern real quick.
I'm going to delete all these points
because I don't need them now.
(clicks)
Let's delete this one as well.
I'm going to make a circle off to the side,
go up here and select Circular Pattern.
Now, you can see I had that arc already selected.
It naturally selected the origin as my center point,
but you can select any point or arc
as the center point for the pattern.
Here I can adjust the number of times
that it's patterned, if it's equal spacing or not.
I can also do it by degrees, so let's say
I want five degrees of rotation,
I can up that to 10 if maybe I want 10,
and you can see the effect that it has here.
So, each position is going to be 20 degrees
along this, and it's going to do it eight times.
Eight instances spacing 20 degrees.
Now, I can go back and click Equal Spacing,
(clicks)
and you see that it made the range over 140 degrees.
Change this back to 360 and I've got
an equal-patterned arc around that circle.
Same thing applies to the instances that we want to skip.
By clicking on this window we can go in here
and skip a couple of them if we like.
Hit green to accept, and we've got a circular pattern.
Also, when you click on this you have to go
to the Existing Relations and right click Edit Pattern
to get back into the window and edit it.
If you want, you can also do things
(clicks)
like adjust the degrees, adjust the radius,
other things like that.
Because I have this in a locked position
it's not allowing me to do that,
but it gives you a lot of parameters
in here that you can adjust.
So, that's using Linear Sketch Pattern
and Circular Sketch Pattern to pattern your sketch entities.
