so let's go back to our rectangle tool
and we're gonna draw a rectangle in the
top right quadrant of our screen and
then we're going to explore how we can
stay on axis when we're drawing in 3d so
I'm gonna click once in the top right
corner move my cursor to suggest a
direction and then type in 1 0 ' comma 5
' enter so we're gonna make that
rectangle at 10 feet by 5 feet next I'll
push down on my scroll wheel button and
orbit into a 3d view trying to get to a
view that kind of matches mine so you
have your red axes projecting to the
right and the green axis projecting to
the left now we have three techniques to
stay on axis when we're drawing in 3d so
we're gonna go back to our line tool and
the first one is kind of the easiest one
this is a fail-safe method so we're
gonna click once on that front right
corner and that starts our line and now
as I start moving around I can tap the
up arrow key when I tap that up arrow
key it automatically locks my blue axis
so now I don't have to fish around and
find the blue axis I'm locked on there
so either the up or the down arrow key
will lock that I can unlock it by
tapping the up arrow key again so it's a
toggle I'm gonna tap it one more time to
turn that on and lock my blue axis move
my cursor to suggest a direction and
then type 3 ' enter so now I've drawn
that line straight up on the blue axis
by 3 feet you can see here I'm still
locked on that blue axis so now I want
to draw on the green axis so I can tap
the left arrow key and now I'm drawing
on my green axis so I remember the the
arrow keys and the colors of the axes by
right is red so when I tap the right
arrow key that's the red axis left arrow
key is green and up or down is blue so
now as I come over here on my green axis
all I need to do is define a distance
because our active line is locked I can
touch that back point and click to
define my distance
then click again to finish so again now
that we have a closed loop of coplanar
edges we get a surface that fills it so
our first technique for locking our
first technique for staying on axis when
we're drafting in 3d is using those
arrow keys to lock an axis now let's
take a look at how we can manually lock
an axis so instead of that automated
process of just locking it this time
we're gonna find our axis and then hold
down shift and that's gonna lock it now
this is not a toggle so we're gonna
click on this back top corner and then
I'm gonna move my mouse around and find
my red axis and it tells me I'm on my
red axis and I can hold down the shift
key notice that the active line gets
bold and it's locked on that red axis as
long as I hold the shift key down now if
I was to let go that shift key I lose my
locked axis so I need to find my red
axis I get a cue that says on red axis
hold down shift and then just like we
did before I'm gonna come down here and
click to define my distance let go of
the shift key and then we'll click again
to fill in the blanks there so again we
have our closed loop of coplanar edges
and we've created a surface and you can
see that we're really staying on axis
when you start to orbit everything is
drawn perfectly at right angles in 3d
now let's orbit to a view that is
strategic for what we're working on what
if I was to try and draw in this surface
by looking at it like this I'm gonna
have a lot of inferences kind of
projecting on two different surfaces and
points that are that are on my screen
right now so if I was to kind of orbit
this way we have nothing beyond when
we're drawing this back wall so we're
gonna click once on that top back corner
to start and this time instead of
locking axes we're going to use the
inference engine in 3d so as I come over
here on the green axis paying very close
attention to which direction I'm drawing
it because I want to come forward on the
green you can see I'm already getting an
inference projecting from that front top
corner
now if I want to encourage an inference
I can always come down here and hover on
an endpoint and now I get my blue
inference projecting up so that dotted
blue line is an inference line my active
line is green and I can click where they
intersect and now connect the dots so
those are our three techniques for
staying on axis when we're drafting in
3d we use our arrow keys tap those as a
toggle to lock our axes we can find an
axis and hold down shift that'll lock an
axis or a more advanced technique is to
use the inference engine and pay very
close attention to which direction we're
drawing in and which inference line is
projecting forward so at this point we
can just connect our dots from corner to
corner and finish off that 3d shape now
to finish up this exercise let's go to
window and take a look at our instructor
so under window instructor now this is a
great exercise a five minute exercise to
do on your own open up the instructor
and explore all the different tools on
your large tool set or for that matter
any of the icons on any of the toolbars
so you could just go through and open up
all these toolbars and then start
clicking when I click on the Select tool
the instructor switches over and it
tells me how the Select tool works so
now you can see we have modifier keys
what I I need to hold down to make it do
different things and we also have a
couple of articles on advanced
operations so you can see as you click
through these guys the instructor will
continue to tell you different lessons
on each of these tools so this is a
great way to get started on learning any
software's to just go through and take a
look at all the tools that are available
to you
