- What's useful with this, we'll take a look.
In this case I have kind of a circular board,
so it might be useful to set up a polar grid as well.
So let's say I want to create some more customized grids.
I can go into my Grids here, and I usually just choose
the Grids here to jump into my Grid Manager.
And here we're seeing all of the specified
or customized grids that we may want to set up.
So there's always going to be this one default here.
That's just my default grid that I'm always
going to be seeing coming in here.
And it's based off that snap that I just set up right now,
but I can change it through here as well,
so if I just double-click here, as an example, I can input
a bunch of information, whatever I may need here.
So my step size, again I set it to be 100 there.
I've set up fine and coarse lines
by a five-times multiplier.
What that means is that you can see my
two different lines here, and it's one, two,
three, four, five grid points here,
and then we have the larger grid on top of that.
I can change these multipliers to ten times, for example,
and see how that has made the change there.
Change the colors of the grids, whatever it may be
to suit your exact needs and preferences.
I'm gonna go back to five times here, hit Apply, and hit OK.
So that's just my default there.
I can also add and customize as many
custom grids as I may need as well.
So in this case I can just right-click anywhere here.
I have add a Cartesian grid.
Of course I can do that if I'd like
to show, I'll add one Cartesian grid here.
I'll leave it pretty much the same,
just change the color here, so like color change.
And then we can see that new custom Cartesian grid
there as well that I've just thrown in there.
So you have a bunch of information you can customize here.
Origin point, where do you want to start?
I started at zero-zero.
What quadrant I want to go in,
I'm going in the first quadrant here;
and what my step might be here, in this case 15 mil,
100 mil, whatever it may be; and width,
essentially how far I'm going to extend that grid.
Let's change that to 500, let's say,
and we can see now it's extended to 500,
or 1,000, or whatever it may be.
So you can customize your grids as needed there.
I'll just say OK to that.
But maybe more importantly in this case,
hang on to my default grid because I'm happy with that one,
then I probably also want to add maybe a polar grid,
so I can easily place components
on some polar or circular grid points.
Of course, you can delete any of these after the fact
if you figure, I don't need this grid anymore,
I can delete it, or I can just hide or turn it off here.
So I have comp and non-comp here.
You can turn these on or off.
Essentially just means, will the grids be shown
when I'm placing components or when I'm placing
any non-components as well.
Or you can turn them both off and then it's pretty much
gonna be hidden at all times until I turn those back on.
This is pretty much just hiding or showing your grids.
I'm gonna try to add a polar grid, so again right click,
and Cartesian grid, I've already done this,
and Add Polar Grid here.
I can change the names here,
everything like that, I can customize.
So I'm gonna add a polar grid here maybe again,
just change the colors so we can distinguish
a little bit easier between my various grids here.
Do something like this, some green colors.
And in this case, let's try to hit Apply here,
see how it looks.
So there's my polar grid coming in currently.
But I probably want to change
some of this information as well.
I'm going to say, I actually want it going
all the way around, so I'm gonna say 360 degrees.
Looks good.
And then I can change my radial range
and everything like that as well, angular step,
whatever it may be to suit my exact needs,
and see how these may change the size
and the spacing and my grid snapping as well.
Again, I'm starting at zero-zero here.
Let's see, my radial step is 50 mil or so,
all the way around 360 degrees, and again,
how far do I want to push; I think this was,
if I remember, about four inches.
So let's say that this may be
2,000 mil or so.
So now we can see we have a fairly customized
radial or polar grid here.
Let's say OK to that; I'll leave it on for now.
And so now I'll just be able to place components
in a more polar or circular manner much easier,
so I'll be able to use each of these polar grid points
to place my electrical components or whatever it may be.
We're gonna use this once we get into
actually placing some footprints and some components.
