- [Instructor] We're staying in
our ground floor plan revision five .dwg file.
And what we're going to take a look at now
is our line type scale.
Also known as the LTSCALE
in your AutoCAD drawings.
Now if the drawing zoomed in where it was
in the previous video,
and I just want you to take a look
your grid lines over here,
can you see they're using like a dash double dot kind of
line type there.
Now that particular line type as you can see
it's not really standing out that much at the moment
and what you'll also notice if you hover over a grid line
can you see the line type is not set
ByLayer either?
So what we do,
is go and find that particular layer
which is Z-030-M GRID.
So I'm going to go to my Layer Properties
in my layers panel here,
and I'm going to find that grid
it's down near the bottom of the list.
There we go,
Z-030-M GRID.
It's that one there.
And what you can see there is
that it should be using a continuous line type
which I don't really want it doing.
So I'm going to change this
to the Grid Line 1-2 line type.
So when I OK that now
all my grid lines are following
that Grid Line 1-2.
So what that means is
I can set all of my grid lines to ByLayer
instead of this Grid Line 1-2.
So I'll close the Layer Properties manager.
And can you see there,
it's using the Grid Line 1-2
but I want that to say
basically line type ByLayer.
So what I'm going to do now
I'm going to just double click on the wheel to zoom extents.
Now there's not that many grid lines to select
in the drawing.
So if I do a little crossing selection here
click here,
and just drag upwards kind of
sort of left to right ish like that.
You can see they're selected there.
Like so,
so what I'll do is I'll change
that in the properties there.
Like so,
and I want that to be ByLayer like so
there's all the horizontal grid lines done
hit Escape to deselect,
and then I'll do the same.
It's a little crossing selection going across this way.
Like so
you noticed that I've selected a doorway as well.
Just hold down Shift,
click on the doorway to remove that from the selection set.
So there's our grid lines there
again in the properties panel
I'm going to set to ByLayer.
So when I hit Escape now,
and I zoom in on these grids
let's go to this top right corner
if I hover there now,
can you see that grid line is ByLayer for color
ByLayer for line type
and it's on the grid layer.
So,
here's what I need to check
that LTSCALE those
sort of grid dashes aren't showing up very well are they?
So here's where I can work with that LTSCALE
double click now on the wheel to zoom extent.
And when you zoom out,
can you see that LTSCALE
looks like a continuous line type.
So we need to globally change the LTSCALE
very quick and easy to do.
So if I type LTSCALE as one word
and press Enter
I can now do a global line type scale factor change.
Now at the moment,
it's set to one
which is in essence, a hundred percent.
So it's set to a scale of one.
Now what that means is that scale of one means
that those grid line types
aren't really doing their job properly.
So if I do a global change,
that's going to change every dashed
and dotted line type in the drawing.
So let's do that.
Let's change that to say 25
and press Enter.
So we're making it all 25 times bigger
notice the grid lines change
but the problem I've got is everything else
that uses a dashed or dotted line type
has also changed.
You'll notice this doorway over here.
Can you see, it's all gone dashed on me there.
These lines here are all dashed where I've set
out the desks in the hot desking area.
So that means that basically
everything that uses a dashed or dotted line type
is now 25 times bigger.
Now you might not want that to happen.
So what we might want to do here is cheat
and use basically a selection set
that only selects the grid lines.
So we need to select those grid lines
kind of individually but as a group, if you get my meaning.
So we'll go over to the undo here
on the quick access toolbar
and undo that.
Now you remember when we set the grids
and we change their line type to ByLayer.
So we need to do a little sort of crossing selection here.
So just drag across like that
until you get all those grids selected
hold down Shift to deselect that door again
we don't want to mess up the door
and then I'm going to do another
little crossing selection here.
So it's a click
release the mouse button
and just drag upwards until you get that little green dash
selection window and click again.
So I've now only got the grid lines selected.
So it's now a right click
and I can go to Properties on the shortcut menu
and on the properties pallet
I can change the line type scale
of just these 12 lines that form the grid lines.
So now going there,
delete the one put in 25, press Enter.
You can see the grid lines update
close the properties pallet
by clicking on the cross,
hit Escape to deselect.
Can you see now the doorway
still is using the appropriate setup
for its line type there
and also the hot desking areas can you see
are also using their appropriate line type as well.
It's only the grid line that have changed
because we've done an individual
line type scale change in that particular case.
