- [Instructor] Once we've drawn out the general shape
of our new symbol,
we'll probably want to finish it off with
electrical connection points so we can actually
connect it within our project
and throw in some attributes.
Essentially some descriptions and some variables
that will come in with this symbol.
So let's start with the electrical connection points.
I'll want to jump into my edit symbol tab here
and I have a number of connection point insertion tools.
So I can insert individual connection points,
or if I choose multiple connection points
I can try to throw in a whole bunch of connection points
all at once.
So I'll try multiple connection points here.
And I'm going to hit add.
And here I just have one set of connection points
I'm going to use.
The first thing I'd like to do is define the circuit type,
so this is a fuse
so I'm going to check what
circuit types I have available to me.
There's a fuse right there.
If I don't see it I can go to more circuit types
and check the whole list,
see if I can find one of these that would be useful for me.
And what this is essentially is,
just a nice way to so you can search for these values
as well as these are the circuits.
So again remember my circuit states,
the green, blue, and red.
So these are important to get right so that they'll match up
with the actual manufacture parts and so on.
So in this case if it's a fuse
I'd probably like a fuse disconnector circuit type.
And in this case it's the three phase
so I probably want three circuits
and for each circuit or each phase
I'm going to have two terminals,
one on either side of the fuse.
And then as for information transmission,
in this case I do want disconnectable.
If I hit that drop-down I have a couple different
options here.
So what disconnectable means is that essentially
the potential on either side of this component
is disconnected,
so I have a equipotential of some value on this side
and then a different equipotential on the other side.
So for a fuse disconnectable would make sense.
If it was something like a terminal for example,
where it's going to be the same potential
on either side of the terminal,
you would want to use passing in that case.
But for a fuse we're going to use disconnectable
and then I think I'm okay with all of these options
so I can just hit OK.
And there you can see I have my three circuits.
Each of those circuits have two terminals.
And I want to place these in the correct location
so it aligns and connects nicely with the rest of my
electrical design.
Here are each of my connection points,
you can see on my mouse cursor here.
And the way you'd like to set these up
is you actually want to hit the right mouse button
and that will rotate this electrical connection point
as you can see.
And the way that it should be set up is that the
large black circle should be where your wire
is coming in from,
and the smaller white circle
should be where the wire is terminated.
So in this case we'd want to,
on the left hand side of our fuse,
throw something like right here.
That would be my electrical connection point.
And where it's going to connect in my
actual design schematic.
So this would be my very first terminal
so I'm going to place it here.
We have some automatic attributes coming in there.
So that's the terminal number and so on.
Then on the left hand side I can check out which terminal's
coming next,
so now it's again the same circuits or the same phase
but the different terminal numbers.
That would be this connection point here.
And again I want to make sure that the
connection point is coming in the right direction
so I'll need to hit the right mouse button click again
to rotate this,
and I want it coming in like this.
So again I always want the large black circle
to be where the wires would be coming in from.
If you do it the wrong direction you're going to
run into some wiring issues in your designs,
so you might just have to make those fixes
to your symbols if you make that mistake.
So I would want my second terminal placed here.
And then just the same for all the rest.
And now I'm circuit one, terminal two.
I want to place this one here.
And here.
And so on.
So now I have a number of attributes already place here.
These are all the terminal numbers.
Let's say I want to throw in some additional attributes,
say for example the component tag numbers
usually thrown in,
like the f one for example if it's a fuse.
Maybe even the manufacturer name or the part number.
You can really throw in any amount of information
you'd like and that's all going to come in automatically.
So to do this I can just go into insert attribute.
And this gives me my attribute management window
and this is a list of pretty much all of the information
that I've placed throughout my whole project,
is available to me.
So if I want the short tag for example,
so that would be my fuse if it's f one or f two or whatever,
or whatever fuse number it might be.
Maybe I want to throw that one in there.
And maybe I also want some manufacturing information
so if I throw in the manufacturer part reference
so that might throw in the manufacturer name or description
and so on.
And I just have a whole bunch of information
you can pick and choose.
This is essentially all of the attributes that you want
to come in with this symbol.
So maybe I also want let's say,
the current rating of this specific fuse
or whatever it may be.
Throw in a couple of other values.
And once I'm happy with all my choices I just say OK.
And I can place those wherever I'd like.
While placing I have a number of options as well.
What text size what I'd like it to be, what font,
left justified, right justified, and so forth.
And I have all these options here.
And I'm just going to throw these values below.
Let's just throw it around here just as an example.
So when I place my symbol,
the symbol should come in,
it should align correctly with the connection points
and a bunch of information related to this fuse
should come in with the attributes.
