Dialogue: 0,0:01:44.41,0:01:47.32,Default,,0000,0000,0000,,the example used in this visual guide
Dialogue: 0,0:01:47.61,0:01:48.82,Default,,0000,0000,0000,,is the clamp shown here,
Dialogue: 0,0:01:48.85,0:01:50.74,Default,,0000,0000,0000,,which is a Bessey 6-inch clamp.
Dialogue: 0,0:01:51.61,0:01:51.85,Default,,0000,0000,0000,,We
Dialogue: 0,0:01:51.89,0:01:53.04,Default,,0000,0000,0000,,modeled this

Dialogue: 0,0:02:01.76,0:02:02.28,Default,,0000,0000,0000,,OK?
Dialogue: 0,0:02:02.49,0:02:03.64,Default,,0000,0000,0000,,Before we talk about the standards though,
Dialogue: 0,0:02:03.84,0:02:06.31,Default,,0000,0000,0000,,super valuable for you to know that, "Above all,
Dialogue: 0,0:02:06.72,0:02:07.99,Default,,0000,0000,0000,,drawings should be clear,
Dialogue: 0,0:02:08.48,0:02:08.87,Default,,0000,0000,0000,,complete,
Dialogue: 0,0:02:09.00,0:02:10.43,Default,,0000,0000,0000,,and unambiguous."
Dialogue: 0,0:02:10.80,0:02:13.94,Default,,0000,0000,0000,,Now it's valuable to create drawings that are also pleasing to look at
Dialogue: 0,0:02:14.20,0:02:17.12,Default,,0000,0000,0000,,and require the least amount of energy to be correctly understood,

Dialogue: 0,0:02:19.72,0:02:19.96,Default,,0000,0000,0000,,OK?
Dialogue: 0,0:02:20.04,0:02:21.35,Default,,0000,0000,0000,,But to understand the standard,
Dialogue: 0,0:02:21.42,0:02:22.58,Default,,0000,0000,0000,,you're gonna need to know
Dialogue: 0,0:02:22.76,0:02:24.40,Default,,0000,0000,0000,,the following words.
Dialogue: 0,0:02:24.59,0:02:26.47,Default,,0000,0000,0000,,First of words you're gonna need to know are.

Dialogue: 0,0:02:30.98,0:02:33.59,Default,,0000,0000,0000,,basically the overall sheet size
Dialogue: 0,0:02:34.77,0:02:35.87,Default,,0000,0000,0000,,and its format,
Dialogue: 0,0:02:35.95,0:02:37.51,Default,,0000,0000,0000,,which is like these lines around the side,
Dialogue: 0,0:02:37.67,0:02:37.87,Default,,0000,0000,0000,,OK?
Dialogue: 0,0:02:37.88,0:02:38.87,Default,,0000,0000,0000,,And then the Title Block,
Dialogue: 0,0:02:38.95,0:02:42.26,Default,,0000,0000,0000,,which is this thing down in the bottom right-hand corner.
Dialogue: 0,0:02:43.71,0:02:43.98,Default,,0000,0000,0000,,All right,
Dialogue: 0,0:02:44.06,0:02:45.53,Default,,0000,0000,0000,,what else are you gonna need to know?
Dialogue: 0,0:02:45.78,0:02:46.98,Default,,0000,0000,0000,,You're gonna need to know that
Dialogue: 0,0:02:47.83,0:02:51.19,Default,,0000,0000,0000,,these things in this area are called isometric,
Dialogue: 0,0:02:51.51,0:02:51.94,Default,,0000,0000,0000,,excuse me,
Dialogue: 0,0:02:51.99,0:02:53.65,Default,,0000,0000,0000,,called orthographic views.
Dialogue: 0,0:02:53.66,0:02:55.46,Default,,0000,0000,0000,,These are orthographic projections.
Dialogue: 0,0:02:55.79,0:02:57.31,Default,,0000,0000,0000,,In this area right up here,
Dialogue: 0,0:02:57.55,0:03:00.06,Default,,0000,0000,0000,,these are our isometric views,

Dialogue: 0,0:03:00.67,0:03:03.39,Default,,0000,0000,0000,,And then we have Auxiliary Views such as these,
Dialogue: 0,0:03:03.47,0:03:05.86,Default,,0000,0000,0000,,but there are many kinds of auxiliary views.
Dialogue: 0,0:03:06.19,0:03:07.87,Default,,0000,0000,0000,,This is called the Detail View.
Dialogue: 0,0:03:08.31,0:03:12.23,Default,,0000,0000,0000,,The Detail View is being pointed out right in this area
Dialogue: 0,0:03:12.65,0:03:13.58,Default,,0000,0000,0000,,with the A
Dialogue: 0,0:03:13.89,0:03:16.81,Default,,0000,0000,0000,,and then it is zoomed into that area right in here,
Dialogue: 0,0:03:16.89,0:03:17.88,Default,,0000,0000,0000,,and we can see what's going on.
Dialogue: 0,0:03:17.93,0:03:18.33,Default,,0000,0000,0000,,But
Dialogue: 0,0:03:18.57,0:03:19.60,Default,,0000,0000,0000,,there are also
Dialogue: 0,0:03:19.88,0:03:20.97,Default,,0000,0000,0000,,Section Views,
Dialogue: 0,0:03:21.27,0:03:22.41,Default,,0000,0000,0000,,Scales Views,

Dialogue: 0,0:03:25.61,0:03:27.49,Default,,0000,0000,0000,,These are all called Auxiliary Views.
Dialogue: 0,0:03:27.53,0:03:28.48,Default,,0000,0000,0000,,You need to know those
Dialogue: 0,0:03:28.73,0:03:29.70,Default,,0000,0000,0000,,words as well.
Dialogue: 0,0:03:31.44,0:03:32.03,Default,,0000,0000,0000,,All right,
Dialogue: 0,0:03:32.16,0:03:36.51,Default,,0000,0000,0000,,other thing that's going on here is that there is an Assembly Drawing,
Dialogue: 0,0:03:36.88,0:03:38.56,Default,,0000,0000,0000,,and there are Part Drawings.
Dialogue: 0,0:03:38.72,0:03:39.52,Default,,0000,0000,0000,,Assembly drawings,
Dialogue: 0,0:03:39.53,0:03:44.43,Default,,0000,0000,0000,,as shown on the left are a collection of a whole bunch of parts,
Dialogue: 0,0:03:44.80,0:03:47.53,Default,,0000,0000,0000,,and a really important part of the assembly drawing
Dialogue: 0,0:03:47.53,0:03:50.43,Default,,0000,0000,0000,,is the bill of materials or the parts list.
Dialogue: 0,0:03:50.44,0:03:51.47,Default,,0000,0000,0000,,It is sometimes called,
Dialogue: 0,0:03:51.48,0:03:52.96,Default,,0000,0000,0000,,and it's this thing that's right here.
Dialogue: 0,0:03:53.83,0:03:57.12,Default,,0000,0000,0000,,And each one of these parts in the Parts List
Dialogue: 0,0:03:57.47,0:03:59.21,Default,,0000,0000,0000,,refers to
Dialogue: 0,0:03:59.78,0:04:00.59,Default,,0000,0000,0000,,another
Dialogue: 0,0:04:00.76,0:04:01.55,Default,,0000,0000,0000,,CAD model.
Dialogue: 0,0:04:02.72,0:04:03.77,Default,,0000,0000,0000,,And it has
Dialogue: 0,0:04:03.91,0:04:06.65,Default,,0000,0000,0000,,its own drawing like what we see right over here.
Dialogue: 0,0:04:06.94,0:04:07.16,Default,,0000,0000,0000,,So,
Dialogue: 0,0:04:07.18,0:04:09.59,Default,,0000,0000,0000,,the Assembly Drawing is just the assembly
Dialogue: 0,0:04:09.98,0:04:11.51,Default,,0000,0000,0000,,of all the pieces,
Dialogue: 0,0:04:11.86,0:04:14.37,Default,,0000,0000,0000,,and then all the parts are separate
Dialogue: 0,0:04:14.74,0:04:15.90,Default,,0000,0000,0000,,drawings.
Dialogue: 0,0:04:15.94,0:04:16.18,Default,,0000,0000,0000,,OK,
Dialogue: 0,0:04:16.22,0:04:18.24,Default,,0000,0000,0000,,they're controlled differently and so on and so forth,
Dialogue: 0,0:04:18.30,0:04:19.18,Default,,0000,0000,0000,,they're separate drawings.
Dialogue: 0,0:04:19.26,0:04:19.69,Default,,0000,0000,0000,,OK,
Dialogue: 0,0:04:19.94,0:04:20.42,Default,,0000,0000,0000,,next piece.
Dialogue: 0,0:04:21.33,0:04:21.53,Default,,0000,0000,0000,,Alright,
Dialogue: 0,0:04:21.61,0:04:24.65,Default,,0000,0000,0000,,we just talked a second ago about the bill of materials or the parts list,
Dialogue: 0,0:04:24.69,0:04:27.50,Default,,0000,0000,0000,,which is a list of all the parts and the quantity
Dialogue: 0,0:04:27.77,0:04:29.72,Default,,0000,0000,0000,,of those parts in the assembly.
Dialogue: 0,0:04:30.13,0:04:30.92,Default,,0000,0000,0000,,And then
Dialogue: 0,0:04:31.45,0:04:33.82,Default,,0000,0000,0000,,in the Part Drawings and Assembly Drawings,
Dialogue: 0,0:04:33.83,0:04:34.72,Default,,0000,0000,0000,,we have notes.
Dialogue: 0,0:04:35.17,0:04:37.88,Default,,0000,0000,0000,,Those notes always appear directly above
Dialogue: 0,0:04:38.40,0:04:39.21,Default,,0000,0000,0000,,the title block.
Dialogue: 0,0:04:41.94,0:04:47.11,Default,,0000,0000,0000,,Another really important thing, in the title block is the title block tolerances.
Dialogue: 0,0:04:47.37,0:04:49.62,Default,,0000,0000,0000,,The title block tolerances specify
Dialogue: 0,0:04:49.93,0:04:52.24,Default,,0000,0000,0000,,how precise a part needs to be made,
Dialogue: 0,0:04:52.69,0:04:55.40,Default,,0000,0000,0000,,and in our title block that we use for the class,
Dialogue: 0,0:04:55.69,0:04:59.28,Default,,0000,0000,0000,,both inch and millimeter are specified in the same one,
Dialogue: 0,0:04:59.73,0:05:00.36,Default,,0000,0000,0000,,and
Dialogue: 0,0:05:00.89,0:05:04.20,Default,,0000,0000,0000,,this helps us to know the precision of the parts that need to be made.
Dialogue: 0,0:05:04.73,0:05:05.28,Default,,0000,0000,0000,,All right.
Dialogue: 0,0:05:05.69,0:05:05.81,Default,,0000,0000,0000,,Now,
Dialogue: 0,0:05:05.82,0:05:09.40,Default,,0000,0000,0000,,a few more things you need to know before we even get into the standards,
Dialogue: 0,0:05:09.81,0:05:11.21,Default,,0000,0000,0000,,some vocabulary,
Dialogue: 0,0:05:11.57,0:05:11.89,Default,,0000,0000,0000,,this

Dialogue: 0,0:05:14.29,0:05:16.93,Default,,0000,0000,0000,,The dimension line has an arrow on the end of it,
Dialogue: 0,0:05:18.26,0:05:20.79,Default,,0000,0000,0000,,and it always has a dimension in the middle of it.
Dialogue: 0,0:05:21.63,0:05:24.70,Default,,0000,0000,0000,,An Extension Line is the thing that the arrow is pointing to,
Dialogue: 0,0:05:24.71,0:05:25.70,Default,,0000,0000,0000,,and it always
Dialogue: 0,0:05:26.03,0:05:28.62,Default,,0000,0000,0000,,comes close to but does not touch the part.
Dialogue: 0,0:05:29.19,0:05:29.31,Default,,0000,0000,0000,,See,

Dialogue: 0,0:14:25.43,0:14:28.40,Default,,0000,0000,0000,,quick view of what it is. And having it in this area
