Blueprint, reading views and projections.
00:06
After completing this video, you'll be able to
00:08
review a blueprint, identify areas of a blueprint,
00:12
identify drawing views and recall 1st and 3rd angle projections.
00:17
In this video,
00:18
we'll get started by referencing two supplied pdfs and then
00:21
we're going to open up a fusion 360 design.
00:24
Let's begin by taking a look at projections,
00:27
drawing first angle and third angle PDF S.
00:30
When we think about detailed drawings,
00:32
we have to understand that these drawings
00:34
are conveying information from the person who designed
00:37
the part to the person who's going to manufacture the part or assemble the part.
00:42
In this case,
00:43
the basics that we want to understand are going to
00:45
come down to different projections and different drawing views.
00:50
These detailed drawings are intentionally simplified removing
00:53
extra information such as the dimensions,
00:55
tolerances and additional views to make sure that
00:58
we understand the foundational concepts of a detailed drawing
01:02
to get started. We're going to begin looking at our first angle projection.
01:07
First angle projection information can often be found in the title
01:10
block area in the bottom right hand corner of a drawing.
01:14
We can see this by the symbol that we see in the title block.
01:18
First angle projection will show the side view on the left hand side
01:22
and it will show the front view on the right hand side.
01:25
In this case,
01:26
you'll note that there's a lot of different areas of
01:28
this title block which have intentionally been left empty.
01:31
And we're going to review those areas later.
01:33
As we look at this detailed drawing.
01:35
It's important to note that in Fusion 3
01:40
the I O or I S O standard and the A sme
01:44
when you're creating a first angle projection drawing,
01:46
you need to use the ISO standard as this will set it as a first angle projection.
01:51
But what does first angle projection actually mean?
01:54
Well, in this case, our front view is gonna be located in the upper right
01:59
hand section.
01:60
Our top view will be located below the front view
02:03
and our right view will be located to the left of the front view.
02:07
Also note in the bottom left hand corner, we're going to see the isometric
02:11
view
02:12
while not all drawings will have these exact views.
02:15
It's important that we represent our 3D models in these two D views as needed.
02:21
In this case, these are going to be our standard views.
02:24
Let's go ahead and take a look at the third angle projection drawing
02:28
while this is a different standard.
02:30
And it's also on a different sheet size it still contains the same information
02:34
again in the title block area which now takes
02:37
up the entire bottom of our drawing sheet.
02:39
We can see a different symbol.
02:40
This is going to be the symbol for third angle projection.
02:44
Again in fusion 360 the A SME standard is
02:47
going to be our third angle projection drawing type.
02:50
When we have a third angle projection,
02:52
our front view is gonna be located in the bottom left
02:56
just above. That will be our top view to the right of it will be our right view.
02:59
And in the upper right hand corner, we can see our isometric
03:02
view.
03:03
Now,
03:03
it's important to note again that this
03:05
detailed drawing contains very little information.
03:08
And it's also important to note that the edges are all shown with full tang agency.
03:14
This is typically not the case for detailed drawings, but for right now,
03:17
it's important that we identify the types of drawing views and
03:21
we don't focus on the specifics of a detailed drawing.
03:24
Now that we've seen two samples, let's go ahead and hop into Fusion 3 60.
03:29
If you've never used Fusion 3 60 before, once you get the program loaded and opened,
03:34
you'll see an untitled document.
03:36
This is default. Every time you open Fusion 3 60
03:39
you want to make sure that you go to the
03:41
upper left hand corner and expand what's called your data panel
03:44
inside of here.
03:45
At the very top level,
03:46
you'll want to create yourself a new project to store all your data.
03:50
In this case, I'm gonna be using a project called 22 Precision Machining Caliper.
03:55
Inside of here,
03:56
I like to create sub folders for different areas of
03:59
the courses that way I can help organize my designs.
04:02
So I created a new folder called S one.
04:04
This is going to be the first section that we're working on
04:07
inside of here.
04:08
I've already uploaded some PDF drawings which can be
04:11
placed inside of the Fusion 3 60 data panel.
04:13
And I also have a design called Caliper Piston programmed.
04:17
There are a couple of different ways that we can get our designs into Fusion 3 60.
04:21
You can use the upload button and then you can either drag and
04:24
drop it in this area or select it from your local machine.
04:28
In this case, what I'm going to do is go to my file menu and select open
04:33
again.
04:33
We can navigate to any of our projects on
04:35
the cloud or we can select open from computer.
04:39
I want to select the drawing projections file.
04:41
In this case, it's a dot F 3D which is a fusion archive file.
04:45
We'll select open and this opens it in Fusion 3 60.
04:49
This design isn't saved yet. So it's important that we save it at this time.
04:54
We'll select save and make sure that the location
04:56
is the project and sub folder that you created.
04:58
In this case, mine is correct.
04:60
But if yours isn't,
05:01
you can use this drop down arrow to navigate to
05:03
your project or create a new project and sub folder.
05:07
I'm gonna select save and note that it's now inside of my data panel,
05:10
inside of my project and sub folder.
05:13
It also tells me the design is currently open
05:15
by myself and I'm gonna hide my data panel.
05:18
Typically, when you're designing in CAD,
05:21
you don't have multiple versions of the same part.
05:23
However, in this case,
05:24
we're going to be taking a look at multiple versions of the same part
05:28
so that we can identify the difference between 1st and 3rd angle projections.
05:32
If we expand our bodies folder,
05:34
note that we have a body for first projection and third projection,
05:38
we also have cubes that represent the bounding boxes for each of these objects.
05:43
These aren't going to be needed for right now.
05:45
So let's make sure that the I icons are deselected
05:48
inside of our sketches folder.
05:50
There's a handful of sketches that we want to take a look at
05:53
to get started. I want to show the right and top sketches.
05:57
When we think about 1st and 3rd angle projections,
05:60
we want to imagine that our objects are in a quadrant.
06:03
Now, in this case,
06:04
our first angle projection is in the first quadrant or the upper right hand.
06:09
If you think about this as starting from zero or 12 o'clock on a clock,
06:13
this 1st 90 degrees is going to represent the quadrant one
06:18
in the Cartesian coordinate system.
06:19
This is actually the opposite orientation than looking at a clock.
06:23
So as we move down into the next 90 degrees, this is gonna be quadrant four.
06:27
And finally over to quadrant three, you might be thinking, why is this important?
06:32
This is the basis for the difference between our view layout.
06:35
When we're in a first projection view.
06:38
This means that our object is to the right of our right plane.
06:41
It's above our top plane and it's in front of our front plane.
06:45
When we're in a third angle projection view,
06:48
it means our object is to the left of our right plane and it's below our top plane.
06:53
It also is going to be placed behind our front plane
06:57
to better represent this. Let's go ahead and hide our right and top sketches
07:01
and let's hide our third projection body and go
07:03
ahead and simply move this to the center.
07:06
We have three sketches, first, front, first, top and first, right.
07:10
And these are going to help us better understand the projections.
07:14
If we rotate our object just slightly using our middle mouse wheel and the shift key,
07:18
you can see that our object is in front of our front view,
07:21
it's to the right of our right view and it's above our top view.
07:25
This is exactly what we saw when we looked at our detailed drawing.
07:29
If you want to remind yourself, go ahead and reopen your first projection view.
07:34
You can see here that our front view is located in the upper right hand corner
07:38
and it's just to the right of our right plane.
07:40
So when we project our view onto that plane, it's shown on the left,
07:44
it's above our top plane. So when projected, it's shown above the top view,
07:49
when we take a look at our third angle projection,
07:51
let's go ahead and hide our first angle projection and bring back our third,
07:55
let's hide our first sketches and show our third sketches
07:58
and then move it into the middle of our screen.
08:00
As mentioned previously,
08:02
this puts our object below the top plane
08:05
to the left of our right plane and behind our front plane,
08:09
we see this. When we look at a drawing view that has third angle projection,
08:13
our top plane will be above the front view and our
08:16
right plane will be to the right of our front view.
08:19
Once again to remind ourselves,
08:21
let's go ahead and open our third angle projection drawing.
08:24
Our front is located in the bottom left.
08:27
Our right view is to the right and our top view is above.
08:30
You can think about this again in that third quadrant.
08:33
So our views are going to be above and to the right.
08:35
When we look at our first angle projection, we're in the first quadrant.
08:39
So our views are gonna be below and to the left.
08:43
Once you understand the basic concept of how our 1st
08:46
and 3rd angle projections are laid out on detailed drawings.
08:49
This will help you better understand 3d geometry.
08:52
If you don't have access to the 3D model,
08:55
understanding the orientation of the part and the drawing views
08:58
is going to be an important aspect of manufacturing the parts
09:02
at this point. Let's make sure that everything we've done is saved before moving on.

08:24
Our front is located in the bottom left.
08:27
Our right view is to the right and our top view is above.
