00:00:00.416 --> 00:00:04.826 A:middle
>> This tutorial is for Lab
14b. Hopefully Lab 14a is fine with just the instructions.

00:00:04.826 --> 00:00:05.256 A:middle
We' re given 

00:00:05.256 --> 00:00:07.286 A:middle
the isometric for
this] object.

00:00:07.756 --> 00:00:15.356 A:middle
We start by creating, under
new file, open template metric.

00:00:16.496 --> 00:00:18.736 A:middle
Note template metric
in millimeters,

00:00:19.516 --> 00:00:21.866 A:middle
and then let's start
at the bottom first.

00:00:22.416 --> 00:00:25.606 A:middle
The base of the figure,
starting with a line

00:00:25.736 --> 00:00:30.986 A:middle
at 00, and then 102, 0.

00:00:32.126 --> 00:00:35.166 A:middle
I'm creating the base
at the bottom, then 102,

00:00:37.236 --> 00:00:49.676 A:middle
129 and then 0, 129 and
just close this rectangle.

00:00:51.036 --> 00:00:55.416 A:middle
And then we're going to select.

00:00:55.776 --> 00:00:58.536 A:middle
Click on R or type R if you want

00:00:58.806 --> 00:01:02.656 A:middle
to change the radius
to the fillets - that's the corners

00:01:02.716 --> 00:01:04.816 A:middle
that are rounded,
20, the radius.

00:01:05.316 --> 00:01:10.646 A:middle
And then click on these two to fillet and then this line

00:01:10.646 --> 00:01:12.886 A:middle
and this line, to the left.

00:01:13.886 --> 00:01:16.086 A:middle
Okay, let's start on the bottom.

00:01:16.956 --> 00:01:21.956 A:middle
Next thing you want to do
is, offset, I'm going to look

00:01:21.956 --> 00:01:25.586 A:middle
at the centers of the
circle, offset by 20.

00:01:26.486 --> 00:01:30.316 A:middle
This line here, also this line
and also this line on this side.

00:01:30.316 --> 00:01:33.226 A:middle
So all those objects are
20 based on the drawing.

00:01:33.756 --> 00:01:39.736 A:middle
And then I'll offset again,
this time a distance of 69.

00:01:40.506 --> 00:01:45.306 A:middle
The distance between the two
sets of circles, 69 on this side

00:01:46.086 --> 00:01:47.876 A:middle
and then I'm going
to create the circle,

00:01:49.386 --> 00:01:53.086 A:middle
center here, of radius 20.

00:01:53.726 --> 00:01:56.296 A:middle
Radius 10, because the
diameter given is 10.

00:01:56.576 --> 00:01:59.436 A:middle
And then instead of
creating the other 3 circles,

00:01:59.436 --> 00:02:03.476 A:middle
I'll just copy the circle here
from this current location

00:02:03.476 --> 00:02:07.136 A:middle
to this, to this and to this.

00:02:07.886 --> 00:02:12.256 A:middle
And, then I'm going to erase
those construction lines

00:02:12.256 --> 00:02:15.876 A:middle
that I offset to
find the location

00:02:15.876 --> 00:02:17.166 A:middle
to the centers of the circle.

00:02:17.426 --> 00:02:20.866 A:middle
So erase, erase, this
one, press enter.

00:02:22.506 --> 00:02:25.156 A:middle
Next thing I'm going to do is
I'm going to change this out,

00:02:25.646 --> 00:02:28.716 A:middle
this isometric views
so I can see the model

00:02:28.716 --> 00:02:30.456 A:middle
as it develops in 3D.

00:02:31.086 --> 00:02:35.786 A:middle
And then I'm going to copy all
of these here, in the bottom.

00:02:35.896 --> 00:02:38.266 A:middle
I'm going to move it up, so copy

00:02:38.266 --> 00:02:41.236 A:middle
from the current location
here, at the base point.

00:02:41.896 --> 00:02:47.376 A:middle
The second base point
is at 0, 0, 26,

00:02:47.856 --> 00:02:50.856 A:middle
I moved it in the z
direction by 26 when copying.

00:02:51.046 --> 00:02:54.436 A:middle
Oh this line here,
is not needed,

00:02:54.436 --> 00:02:57.626 A:middle
in the copy so let's erase that.

00:03:00.666 --> 00:03:03.746 A:middle
And then I'm going to,

00:03:04.116 --> 00:03:07.336 A:middle
create the lines connecting
the quadrants of the circle,

00:03:07.936 --> 00:03:09.226 A:middle
the circles and the arcs.

00:03:09.226 --> 00:03:14.606 A:middle
Remember these are, this
is a y plane so instead of,

00:03:14.606 --> 00:03:17.866 A:middle
repeating that, I'll just
copy one of these to all

00:03:17.866 --> 00:03:22.696 A:middle
of the other locations
for the arcs and also for,

00:03:22.956 --> 00:03:26.036 A:middle
the 4 quadrants of
this circle here

00:03:26.036 --> 00:03:28.406 A:middle
to turn into a wireframe of a cylinder.

00:03:28.536 --> 00:03:32.096 A:middle
4 quadrants here,
for this circle.

00:03:33.086 --> 00:03:35.876 A:middle
And then the 4 quadrants
here as well.

00:03:37.986 --> 00:03:46.536 A:middle
Just copying the line rather
than, here, here, here and here.

00:03:46.536 --> 00:03:48.956 A:middle
And that pretty much
takes care of the base.

00:03:48.956 --> 00:03:51.206 A:middle
Next thing I'm going to do is
I'm going to change my view,

00:03:51.826 --> 00:03:56.746 A:middle
and my UCS to new UCS 3 points.

00:03:57.146 --> 00:04:06.736 A:middle
I'm going to put my X, Y
plane origin X, Y, so that my,

00:04:08.506 --> 00:04:09.726 A:middle
I'm on the right plane now.

00:04:09.816 --> 00:04:12.256 A:middle
So I'm going to create a
line, starting at this point

00:04:12.436 --> 00:04:16.536 A:middle
and then I'm going to use
all the coordinates at 231,

00:04:16.996 --> 00:04:24.276 A:middle
or the incline part at the angle
60 which is 180 minus, 120.

00:04:24.506 --> 00:04:26.906 A:middle
Copy this line here
from this location here

00:04:27.376 --> 00:04:28.636 A:middle
to this other side here.

00:04:29.286 --> 00:04:33.596 A:middle
So that's the starting point
of my incline plane over there.

00:04:33.596 --> 00:04:36.526 A:middle
I'm going to zoom off so I
can see what's going on here.

00:04:37.246 --> 00:04:38.396 A:middle
And then I'm going to try

00:04:38.536 --> 00:04:41.116 A:middle
to locate the centers
of the circle.

00:04:41.116 --> 00:04:45.616 A:middle
Oh I'm going to change my
UCS first along the incline.

00:04:45.876 --> 00:04:47.386 A:middle
So this is my new origin.

00:04:48.266 --> 00:04:52.336 A:middle
This is my new X axis here
and this is my new Y axis,

00:04:52.406 --> 00:04:55.366 A:middle
take note that the
X, Y plane now is,

00:04:55.606 --> 00:04:57.536 A:middle
along that incline plane.

00:04:57.536 --> 00:05:01.176 A:middle
I'm going to create this line
here, okay and then I'm going

00:05:01.756 --> 00:05:05.976 A:middle
to offset that line to find
the center of my circle.

00:05:06.156 --> 00:05:09.956 A:middle
So it's offset by, a
distance equal to 51,

00:05:09.956 --> 00:05:11.376 A:middle
the radius of the semi-circle.

00:05:11.376 --> 00:05:14.316 A:middle
So, this side here,
this side here

00:05:14.316 --> 00:05:17.816 A:middle
and then create the circle
center at the midpoint here

00:05:18.346 --> 00:05:22.286 A:middle
of radius 51 and that should
be turned into the 3 lines.

00:05:23.126 --> 00:05:27.226 A:middle
And then, I'm going to
create another circle,

00:05:27.536 --> 00:05:29.166 A:middle
the same location of the center,

00:05:29.166 --> 00:05:31.416 A:middle
distance with a tiny
little circle.

00:05:32.876 --> 00:05:38.666 A:middle
Radius of 18.5 because
the diameter given is 37.

00:05:38.666 --> 00:05:43.136 A:middle
And then, I'm going to trim
using this as my boundary,

00:05:43.426 --> 00:05:45.256 A:middle
click on, trim this, trim this

00:05:45.256 --> 00:05:47.116 A:middle
and trim this part
of the circle.

00:05:47.776 --> 00:05:50.496 A:middle
And then, erase the
two construction lines

00:05:50.686 --> 00:05:51.906 A:middle
that I don't need now.

00:05:51.906 --> 00:05:55.216 A:middle
This one and this one,
so that takes care

00:05:55.346 --> 00:05:58.086 A:middle
of the back part of
my incline plane.

00:05:59.266 --> 00:06:04.716 A:middle
Now I'm going to copy that, this
one, this one and this one from,

00:06:05.976 --> 00:06:08.426 A:middle
and this one from its
current location,.

00:06:08.426 --> 00:06:14.686 A:middle
The first base point would be,
let's say this end point here,

00:06:14.686 --> 00:06:17.366 A:middle
and I'm going to copy
it in the Z direction.

00:06:17.366 --> 00:06:21.496 A:middle
So my second base point
is 0 on X, 0 on Y and,

00:06:22.036 --> 00:06:28.156 A:middle
the thickness is 26 along Z,
26 enter, so it just moves

00:06:28.156 --> 00:06:30.686 A:middle
in the positive Z direction
it makes a copy of that.

00:06:31.266 --> 00:06:36.326 A:middle
I didn't copy the small circle
because that goes, so I'm going

00:06:36.326 --> 00:06:38.616 A:middle
to make a copy of
it now, of that now.

00:06:38.676 --> 00:06:48.096 A:middle
From its current center, oh,
oh this current location,

00:06:48.096 --> 00:06:53.336 A:middle
the quadrant and
then, copy it at 0, 0,

00:06:53.656 --> 00:06:57.976 A:middle
60 along the Z, positive
Z direction.

00:06:58.086 --> 00:07:02.466 A:middle
So I copy that separately
because of the distance.

00:07:02.986 --> 00:07:06.066 A:middle
Now I'm going to connect
the quadrant lines,

00:07:06.516 --> 00:07:08.076 A:middle
to trim them into Y plane.

00:07:08.486 --> 00:07:12.506 A:middle
I'm going to copy
that, copy that to,

00:07:14.246 --> 00:07:16.326 A:middle
the other 3 from this location

00:07:16.326 --> 00:07:20.976 A:middle
to the other 3 quadrants
of, the circle.

00:07:21.276 --> 00:07:26.236 A:middle
And then I'm going to
connect, this quadrant line's,

00:07:26.326 --> 00:07:30.896 A:middle
connecting there, this one from
this quadrant to this quadrant,

00:07:31.766 --> 00:07:33.986 A:middle
and one from this, it
goes to the end point,

00:07:33.986 --> 00:07:36.306 A:middle
this point to the end
point here, or the arc.

00:07:40.126 --> 00:07:43.406 A:middle
Okay, next thing I'm
going to do is oh.

00:07:43.596 --> 00:07:47.116 A:middle
I'm going to construct this line
here, at, in the middle here.

00:07:49.856 --> 00:07:57.776 A:middle
Now, next thing I want to
do is to trim, now I'm going

00:07:57.776 --> 00:08:02.916 A:middle
to move my UCS to this new plane
here in order to construct the,

00:08:03.676 --> 00:08:07.496 A:middle
medium size circle for X, Y,

00:08:11.606 --> 00:08:15.546 A:middle
along that incline plane I
needed to turn on the center

00:08:15.546 --> 00:08:17.766 A:middle
so I can find the
location of the center.

00:08:18.116 --> 00:08:21.516 A:middle
So I'm creating a circle, with
centers the same as the center

00:08:21.516 --> 00:08:24.306 A:middle
of the arc, click on
the arc a little bit,

00:08:24.386 --> 00:08:27.796 A:middle
now that's the center
of the, the semi-circle

00:08:27.886 --> 00:08:30.976 A:middle
on the top incline
plane, that's my center.

00:08:31.366 --> 00:08:36.866 A:middle
And my radius would be, 32 which
is 64 given diameter divided

00:08:36.866 --> 00:08:38.866 A:middle
by 2, I'm going to copy that.

00:08:40.056 --> 00:08:42.816 A:middle
And that from its current
location which is the center

00:08:42.816 --> 00:08:47.966 A:middle
and then copy that in the Z
direction add, don't forget

00:08:48.066 --> 00:08:56.346 A:middle
to add 0, 0, 34 which is
60 minus 26, the thickness.

00:08:57.456 --> 00:09:02.626 A:middle
That looks fine and then I
will, connect the quadrant lines

00:09:02.836 --> 00:09:08.586 A:middle
from the, two medium size
circles, one here and then copy

00:09:08.586 --> 00:09:13.106 A:middle
that line to the other
3 quadrant locations.

00:09:13.386 --> 00:09:14.686 A:middle
Let me zoom in a little bit.

00:09:16.586 --> 00:09:24.416 A:middle
This quadrant here, to this
quadrant here, to this quadrant

00:09:24.506 --> 00:09:28.306 A:middle
down here and one more here.

00:09:32.146 --> 00:09:34.876 A:middle
Okay that takes care
of the incline part so,

00:09:35.676 --> 00:09:40.326 A:middle
we're just missing, oh we
need to trim those lines here.

00:09:40.376 --> 00:09:45.116 A:middle
So trim all your work when
the lines containing the,

00:09:46.156 --> 00:09:48.266 A:middle
the plane containing
the line are

00:09:48.266 --> 00:09:50.196 A:middle
in the same plane
as the X, Y planes.

00:09:50.196 --> 00:10:00.266 A:middle
I'm changing, setting the, UCS
named into, right side view

00:10:00.556 --> 00:10:02.606 A:middle
so that the X, Y is
now parallel to this.

00:10:02.606 --> 00:10:08.136 A:middle
I can do the trim, these
are all my, cutting edges.

00:10:09.416 --> 00:10:12.886 A:middle
All those lines are now
parallel to the X, Y plane

00:10:12.886 --> 00:10:16.776 A:middle
and then hit enter, and then
trim away the part of the line

00:10:16.776 --> 00:10:17.856 A:middle
that you want to get rid of.

00:10:18.176 --> 00:10:21.236 A:middle
Okay it was necessary for us to
change the position of the X,

00:10:21.236 --> 00:10:23.886 A:middle
Y plane otherwise
trim will not work.

00:10:23.886 --> 00:10:29.276 A:middle
So next thing we do is, we
change the position of our,

00:10:29.446 --> 00:10:34.116 A:middle
UCS again to this
time, the top view.

00:10:36.666 --> 00:10:39.536 A:middle
Okay so that the X, Y now
is horizontal and the reason

00:10:39.536 --> 00:10:41.896 A:middle
for that is I'm going to,

00:10:42.136 --> 00:10:45.186 A:middle
draw the two horizontal
lines corresponding

00:10:45.256 --> 00:10:47.456 A:middle
to the triangular wedge.

00:10:47.456 --> 00:10:52.156 A:middle
So I'll start from the midpoint
of this to the midpoint of that

00:10:52.156 --> 00:10:54.726 A:middle
and then that's the
middle of that platform.

00:10:54.836 --> 00:10:57.906 A:middle
I know that the thickness
of the watch is 20

00:10:57.906 --> 00:11:01.576 A:middle
so I'll offset this,
10 on each side.

00:11:01.616 --> 00:11:04.336 A:middle
10 to the left, and
offset it again.

00:11:08.996 --> 00:11:11.786 A:middle
10 to the right,
so those will be,

00:11:12.216 --> 00:11:16.836 A:middle
the 2 and I'll erase
this one in the middle.

00:11:17.396 --> 00:11:20.776 A:middle
So that takes care of the bottom
part of the triangular wedge.

00:11:20.776 --> 00:11:22.626 A:middle
I'm going to change my UCS again

00:11:22.936 --> 00:11:24.796 A:middle
to the incline by
using 3 points.

00:11:25.326 --> 00:11:28.726 A:middle
Origin here, X axis here,

00:11:28.976 --> 00:11:32.006 A:middle
and the Y axis along this
line, midpoint to the line.

00:11:33.026 --> 00:11:39.256 A:middle
Because I'm going to make
a line, from this end here,

00:11:39.256 --> 00:11:46.206 A:middle
and I want it to go along the
current direction of Y. So at 0,

00:11:47.546 --> 00:11:51.126 A:middle
76 along Y gives me that line.

00:11:52.216 --> 00:11:57.596 A:middle
Copy that line, from its
current location here, to here,

00:11:57.596 --> 00:11:59.316 A:middle
that's the other
side of my wedge.

00:12:00.196 --> 00:12:02.996 A:middle
And now I just need to
create that triangular wedge

00:12:03.136 --> 00:12:08.926 A:middle
with the line command,
line from here to here.

00:12:09.506 --> 00:12:13.906 A:middle
Here to here, and down
here to the bottom here

00:12:13.906 --> 00:12:15.666 A:middle
and then this line okay.

00:12:15.666 --> 00:12:21.556 A:middle
Let me end the line command,
repeat it again, line this time

00:12:21.556 --> 00:12:26.506 A:middle
from this, all the way to the
top of that triangular wedge.

00:12:26.636 --> 00:12:29.886 A:middle
I'm almost done except at
the bottom of that wedge,

00:12:30.296 --> 00:12:35.846 A:middle
I need to trim that line so
trim using these two lines

00:12:35.846 --> 00:12:38.996 A:middle
as my, cutting edges.

00:12:39.366 --> 00:12:41.366 A:middle
Press enter and trim that away

00:12:41.436 --> 00:12:43.796 A:middle
because that whole
thing is one solid line,

00:12:43.796 --> 00:12:45.146 A:middle
and I think I'm done now.

00:12:45.986 --> 00:12:51.326 A:middle
Just to make sure that it looks
correct I'm going to use orbit

00:12:51.486 --> 00:12:55.356 A:middle
to view the object at different
locations and I think I'm fine.

00:12:55.716 --> 00:12:56.676 A:middle
It looks correct now.

00:12:59.276 --> 00:12:59.496 A:middle
Done.
