Speaker 1: In this video, we'll
explain how to navigate around
the drawings. We will look at
the various zoom options
available. Layers are also a key
part in drawing creation. They
can be used to separate out
different entities or to show
different options or types of
service or equipment. This is a
brief introduction for previous
users of 2D CAD so that they can
see the options in the new
interface and as an initial
guide for new users so they can
practice before attending a
course. The most direct way of
navigating a drawing is with the
middle mouse wheel pressing down
and dragging with the mouse will
allow you to pan around the
drawing, scrolling with a wheel
we'll zoom in and out. The last
option with the middle mouse
button is to double click it and
draft site will zoom to fit,
which means the entire drawing
is visible on the screen. This
may well be all that you need to
get your work completed, but it
is not the only way. If we go to
the view tab of the ribbon, we
can see more options. The main
command is zoom. We can use zoom
window to focus quickly on a
specific area. Simply click the
command and click on either side
of the area that you are
interested in. Take time to
familiarize yourself with the
other options that you see. You
can also type in the command.
And if you do so, you'll see the
various
options listed in the command
window. Here, I will use the
selected option or S E and then
select an entity and it will
make it, so that sells my
screen. Beside the zoom tools,
we can see the rebuild function,
which allows us to rebuild or
redraw or regenerate the data on
the screen. After some editing
work has taken place. The view
section that is next is really
only meant for three dimensional
data, although it can be used to
point out where maybe certain
items are not drawn on that flat
zero plane of a system,
something I've seen in the past
on some factory layouts. But
here everything looks fine.
Simply switched back to the top
view and we're good to go. View
tiles allow us to separate the
working space into multiple
sections. So this can be used if
you're trying to navigate
between different areas or
trying to do some work on
different areas. Maybe you're
trying to sort of copy what's
going on. We can then manipulate
between the two to get our work
done. So we can simply switch
back to a single tile when we're
finished here. The other options
for coordinates on this tab are
described in detail on the draft
site essentials training course,
for those that want to know more
for previous uses of 2D CAD you
should be familiar with this
sort of thing, moving the
coordinate system around to aid
with your drafting and
sketch and so on. So having
looked at the navigation of our
drawing, we're now going to turn
to look at layers. Layers are a
critical part of drawings. They
allows us to separate objects in
the design by assigning them to
specific layers. So with this
architectural drawing, you can
see there are a number of layers
involved and we can turn layers
on and off just by clicking on
the green circle. It will then
turn great and objects in that
layer will be hidden. We can
also, if we wish, instead of
hiding layers, you can freeze
layers, doing that the little
blue droplets will turn into a
little ice crystal so we can
tell whether we have frozen that
layer off or allowed it to
remain on. If we're concerned
about amending a layer that we
don't want to amend, then we can
lock it using the padlock. Now I
cannot, I will not be able to
manipulate anything on those
layers of that little padlock as
I try and hover over as if to
select anything. Okay. So let's
have a look at this other little
example, a little bit of a it's
a mold tool. And, uh, we want to
make use of some layers there to
see we've got some for
dimensions, some for hidden
detail. Okay. Maybe we want
another one here. So I want the
hatching to appear on a
different layer. Okay. So we go
into layer
manager there. We can go and add
a new layer. So we simply have
to give it a name. Hopefully
something useful. Okay. We can
then decide, what color are we
going to have that layer, I'm
going to make it blue. If you
want to choose a specific line
style or line weight and so on.
So once we're happy with our
selections, we can hit, okay.
And then if I go and select one
of those objects, so that bit of
hatching there, I can choose to
move it to a different layer
just by using the drop down list
there. So it's now on the hatch
layer and see it's now turned
blue. If I want to move all my
hatching onto that layer, I
could use the properties panel
here. So let's go into the
properties. I can find all my
hatching and assign it all to
the same hatch. You can see us
all turn blue. So this concludes
this section, looking at layers
and the navigation tools to get
a range of drawings. So take
time to familiarize yourself
with these tools.
