- We're starting another video in this chapter now.
And we've got a different drawing for you.
It's called "Units-METRIC.dwg",
and the whole drawing is set up to use metric millimeters.
What we'll do in the next video is I'll talk you through
how we use Imperial units: feet and inches.
And it's actually the same floor plan,
but just scaled to suit the particular unit settings.
So, in units metric,
like I said, we're using metric millimeters.
Now, what you would normally do in the "Model" tab
in a drawing is draw everything real-life, full size.
So the way to check the units
of a drawing are to measure distances.
Now, obviously we've got distances,
we've got grid lines there with dimensions,
and it's pretty obvious that they are in millimeters.
There's no way they'd be meters, or feet, or inches.
Otherwise we'd have some very big buildings going on.
So, the way to just quickly put everything
into context is to use something sensible,
like a doorway or a known distance.
So, if I zoom in on this doorway on the right here,
come right in, close on the doorway, like that.
I can utilize the "Measure" tool in AutoCAD to check this.
So, if I go to the "Home Tab" on the "Ribbon",
"Utilities" panel there.
And just click on the "Measure" flyout
and select "Distance".
Now I'm going to utilize my "Object snaps",
and again, we're going to cover all of these
as we go through the course,
things like: "Objects snaps" and "Measuring distances".
But if I measure from that end point there,
left click to that endpoint there, left click.
You can see that that doorway is 1,155.70
So that's eleven fifty five millimeters, dot seven zero.
So it's roughly 1.15 meters.
So, if you think about that in context,
you know what size that doorway is.
If you think about it,
it's not going to be 1,155 meters, is it?
It's going to be 1,155 millimeters.
I'll just hit "Escape" there to come out
of the measure tool.
And I'll just double-click on the wheel
to "zoom extents" again, like so.
So we can clarify what units
the drawing is using because we've measured
a real-life distance in the "Model" tab,
where everything should be drawn full size.
So if I now type units, like we did previously,
and press "Enter".
You can see that all of our "Settings" for our units there,
set up accordingly.
There's only one that isn't, and that's this one,
"inserted content".
So we'll change that to millimeters
because we know it's a millimeters drawing.
Everything else is set to what we discussed
in the previous units video,
where we've got a decimal length to 2 decimal places,
decimal degrees to 4 decimal places.
"Clockwise" is unticked.
"Direction" again, like I said previously,
set to "East" with the 0.
So we can "OK" there,
and we can "OK" there.
Now obviously, when you're using things
like "Dimensioning" for annotation, like up here,
you can see that these dimensions are obviously
showing us exactly what our design intent is,
and how big the building is going to be
based on the distances between the grid lines.
So that's how you would work
with a drawing in units that are metric.
Now, obviously, I'm using only one instance
of a particular unit and measurement.
I'm only using millimeters.
Now it may be that you have a different drawing
for example, that's in feet and inches.
So you would measure distances differently.
And that's what we're going to look at in the next video,
so that you have a comparison between the two.
