>> This tutorial is for Lab 14b. Hopefully Lab 14a is fine with just the instructions.
We' re given
the isometric for this] object.
We start by creating, under new file, open template metric.
Note template metric in millimeters,
and then let's start at the bottom first.
The base of the figure, starting with a line
at 00, and then 102, 0.
I'm creating the base at the bottom, then 102,
129 and then 0, 129 and just close this rectangle.
And then we're going to select.
Click on R or type R if you want
to change the radius to the fillets - that's the corners
that are rounded, 20, the radius.
And then click on these two to fillet and then this line
and this line, to the left.
Okay, let's start on the bottom.
Next thing you want to do is, offset, I'm going to look
at the centers of the circle, offset by 20.
This line here, also this line and also this line on this side.
So all those objects are 20 based on the drawing.
And then I'll offset again, this time a distance of 69.
The distance between the two sets of circles, 69 on this side
and then I'm going to create the circle,
center here, of radius 20.
Radius 10, because the diameter given is 10.
And then instead of creating the other 3 circles,
I'll just copy the circle here from this current location
to this, to this and to this.
And, then I'm going to erase those construction lines
that I offset to find the location
to the centers of the circle.
So erase, erase, this one, press enter.
Next thing I'm going to do is I'm going to change this out,
this isometric views so I can see the model
as it develops in 3D.
And then I'm going to copy all of these here, in the bottom.
I'm going to move it up, so copy
from the current location here, at the base point.
The second base point is at 0, 0, 26,
I moved it in the z direction by 26 when copying.
Oh this line here, is not needed,
in the copy so let's erase that.
And then I'm going to,
create the lines connecting the quadrants of the circle,
the circles and the arcs.
Remember these are, this is a y plane so instead of,
repeating that, I'll just copy one of these to all
of the other locations for the arcs and also for,
the 4 quadrants of this circle here
to turn into a wireframe of a cylinder.
4 quadrants here, for this circle.
And then the 4 quadrants here as well.
Just copying the line rather than, here, here, here and here.
And that pretty much takes care of the base.
Next thing I'm going to do is I'm going to change my view,
and my UCS to new UCS 3 points.
I'm going to put my X, Y plane origin X, Y, so that my,
I'm on the right plane now.
So I'm going to create a line, starting at this point
and then I'm going to use all the coordinates at 231,
or the incline part at the angle 60 which is 180 minus, 120.
Copy this line here from this location here
to this other side here.
So that's the starting point of my incline plane over there.
I'm going to zoom off so I can see what's going on here.
And then I'm going to try
to locate the centers of the circle.
Oh I'm going to change my UCS first along the incline.
So this is my new origin.
This is my new X axis here and this is my new Y axis,
take note that the X, Y plane now is,
along that incline plane.
I'm going to create this line here, okay and then I'm going
to offset that line to find the center of my circle.
So it's offset by, a distance equal to 51,
the radius of the semi-circle.
So, this side here, this side here
and then create the circle center at the midpoint here
of radius 51 and that should be turned into the 3 lines.
And then, I'm going to create another circle,
the same location of the center,
distance with a tiny little circle.
Radius of 18.5 because the diameter given is 37.
And then, I'm going to trim using this as my boundary,
click on, trim this, trim this
and trim this part of the circle.
And then, erase the two construction lines
that I don't need now.
This one and this one, so that takes care
of the back part of my incline plane.
Now I'm going to copy that, this one, this one and this one from,
and this one from its current location,.
The first base point would be, let's say this end point here,
and I'm going to copy it in the Z direction.
So my second base point is 0 on X, 0 on Y and,
the thickness is 26 along Z, 26 enter, so it just moves
in the positive Z direction it makes a copy of that.
I didn't copy the small circle because that goes, so I'm going
to make a copy of it now, of that now.
From its current center, oh, oh this current location,
the quadrant and then, copy it at 0, 0,
60 along the Z, positive Z direction.
So I copy that separately because of the distance.
Now I'm going to connect the quadrant lines,
to trim them into Y plane.
I'm going to copy that, copy that to,
the other 3 from this location
to the other 3 quadrants of, the circle.
And then I'm going to connect, this quadrant line's,
connecting there, this one from this quadrant to this quadrant,
and one from this, it goes to the end point,
this point to the end point here, or the arc.
Okay, next thing I'm going to do is oh.
I'm going to construct this line here, at, in the middle here.
Now, next thing I want to do is to trim, now I'm going
to move my UCS to this new plane here in order to construct the,
medium size circle for X, Y,
along that incline plane I needed to turn on the center
so I can find the location of the center.
So I'm creating a circle, with centers the same as the center
of the arc, click on the arc a little bit,
now that's the center of the, the semi-circle
on the top incline plane, that's my center.
And my radius would be, 32 which is 64 given diameter divided
by 2, I'm going to copy that.
And that from its current location which is the center
and then copy that in the Z direction add, don't forget
to add 0, 0, 34 which is 60 minus 26, the thickness.
That looks fine and then I will, connect the quadrant lines
from the, two medium size circles, one here and then copy
that line to the other 3 quadrant locations.
Let me zoom in a little bit.
This quadrant here, to this quadrant here, to this quadrant
down here and one more here.
Okay that takes care of the incline part so,
we're just missing, oh we need to trim those lines here.
So trim all your work when the lines containing the,
the plane containing the line are
in the same plane as the X, Y planes.
I'm changing, setting the, UCS named into, right side view
so that the X, Y is now parallel to this.
I can do the trim, these are all my, cutting edges.
All those lines are now parallel to the X, Y plane
and then hit enter, and then trim away the part of the line
that you want to get rid of.
Okay it was necessary for us to change the position of the X,
Y plane otherwise trim will not work.
So next thing we do is, we change the position of our,
UCS again to this time, the top view.
Okay so that the X, Y now is horizontal and the reason
for that is I'm going to,
draw the two horizontal lines corresponding
to the triangular wedge.
So I'll start from the midpoint of this to the midpoint of that
and then that's the middle of that platform.
I know that the thickness of the watch is 20
so I'll offset this, 10 on each side.
10 to the left, and offset it again.
10 to the right, so those will be,
the 2 and I'll erase this one in the middle.
So that takes care of the bottom part of the triangular wedge.
I'm going to change my UCS again
to the incline by using 3 points.
Origin here, X axis here,
and the Y axis along this line, midpoint to the line.
Because I'm going to make a line, from this end here,
and I want it to go along the current direction of Y. So at 0,
76 along Y gives me that line.
Copy that line, from its current location here, to here,
that's the other side of my wedge.
And now I just need to create that triangular wedge
with the line command, line from here to here.
Here to here, and down here to the bottom here
and then this line okay.
Let me end the line command, repeat it again, line this time
from this, all the way to the top of that triangular wedge.
I'm almost done except at the bottom of that wedge,
I need to trim that line so trim using these two lines
as my, cutting edges.
Press enter and trim that away
because that whole thing is one solid line,
and I think I'm done now.
Just to make sure that it looks correct I'm going to use orbit
to view the object at different locations and I think I'm fine.
It looks correct now.
Done.
