The second paragraph concludes the annotation process by showing the final view of the object in paper space. It emphasizes the visibility of the added text annotations in the layout, confirming that all elements of the drawing are now complete and viewable. The paragraph ends with the user remaining in paper space, indicating the end of the annotation process.

Keywords

💡Annotation

Annotation in the context of the video refers to the process of adding descriptive information to a drawing, such as dimensions, text, and symbols, to make it more informative and useful for manufacturing or construction purposes. It is a critical step in completing an AutoCAD drawing, ensuring that all necessary details are clearly communicated. For instance, the script mentions adding linear, angular, radial, and diameter dimensions to a drawing.

💡AutoCAD

AutoCAD is a commercial computer-aided design (CAD) and drafting software application used for creating two-dimensional (2D) and three-dimensional (3D) designs and technical drawings. The video script revolves around using AutoCAD for annotating technical drawings, highlighting its features for dimensioning and adding text to drawings.

💡Dimension Style

Dimension style in AutoCAD is a set of properties that define the appearance and behavior of dimensions in a drawing. It includes settings for text appearance, line styles, and numerical formatting. The script discusses modifying dimension style to adjust the precision of dimension values, such as changing the number of decimal places displayed.

💡Linear Dimension

A linear dimension is a type of dimension used to indicate the length of a straight line or the distance between two points in a drawing. The script provides an example of adding a linear dimension to a vertical line on the right-hand side of an object, specifying the endpoints to place the dimension.

💡Precision

Precision in the context of the video refers to the level of detail or exactness in the numerical values of dimensions. The script describes adjusting the precision of dimension values, such as setting the number of decimal places to two, to ensure that the dimensions are presented with the desired level of accuracy.

💡Angular Dimension

An angular dimension is used to measure and display the angle between two lines or objects in a drawing. The script mentions placing an angular dimension as part of the annotation process, which helps in specifying the geometric relationships within the design.

💡Radial Dimension

A radial dimension is used to indicate the radius of a circle or arc. The script describes adding a radial dimension by selecting the radius and the arc, noting that a center mark is added by default, which is crucial for clarity in the drawing.

💡Center Mark

A center mark is a small cross or dot used in technical drawings to indicate the center point of a circle or an arc. The script discusses the default behavior of adding center marks when placing radial dimensions and the option to manually add center marks to other circles in the drawing.

💡Continuous Dimension

Continuous dimension is a type of dimension that extends across multiple points or objects, showing the cumulative length. The script illustrates the process of adding continuous dimensions to a part, starting from the endpoint of a center mark, which is useful for indicating overall lengths or distances.

💡Multi-line Text

Multi-line text in AutoCAD allows users to add multiple lines of text to a drawing. The script describes the process of adding three lines of text to the drawing, specifying instructions and material properties, which is essential for providing additional information and context to the drawing.

💡Paper Space

Paper space in AutoCAD is a virtual sheet of paper where drawings are plotted or printed. The script mentions moving from model space to paper space to prepare the drawing for printing, highlighting the importance of layout and presentation in the final output.

Highlights

Annotation in AutoCAD includes dimensions and text styles.

Access annotation styles via the annotation drop-down list.

Text styles include font name, style, and height, while dimension styles have standard options.

You can create and modify dimension styles for custom precision.

Added a linear dimension by selecting two endpoints and modifying precision to two decimal places.

A faster method is to select the object directly when placing a linear dimension.

Angular and radial dimensions can be added, with center marks for circular features.

Center marks can be customized through the dimension style settings.

Continuous dimensions can be added without selecting each individual line.

Transcripts

annotation is required to complete an

autocad drawing

two examples of that are dimensions and

text

to access these styles for these you can

go to the annotation drop down list

for example under text style we can see

the font name

the style and the height

under dimension we can see that a

standard

style is provided and you can create new

styles

and or modify them

let's start by adding a linear dimension

i'm going to mention the vertical line

on the right hand side of the object

select the two endpoints and place the

dimension

i can see that it has four decimal

places i don't really want that

so i'm going to adjust the precision of

the output

i'm going to go to the dimension style

modify it

and on the primary units tab from the

precision list

select two decimal places

a little tip instead of selecting the

two end points i can go to linear

right click and just select the object

now i can place the dimension with two

decimal places

on the home tab we have a number of

options

i'm going to go to angular

place the angular dimension

the next dimension i'm going to place is

a radial dimension

select radius select the arc and we'll

notice that a center mark is added as

part of the default behavior

i want to add center marks to the two

other circles but they're not available

on this list so i'm going to go to the

annotate tab

go to the drop down list and select

center mark

the default behavior is a small cross

you can change how that looks

in the dimension style

now i can continue on with the

dimensioning

in this case i'm going to select

diameter and add the diameter dimension

to the

circle

the first linear dimension i'm going to

add is going to be at the top

selecting the endpoint of the center

mark a dimension of 1.5

i'm looking at the overall shape of this

particular part and i know that i need

to add some continuous dimensions so i'm

going to start by adding

a linear dimension

again selecting the end point of the

center mark

instead of adding another linear

dimension i can go to

the continuous dimension

i'm going to use a similar workflow for

the bottom of the part

select the endpoint the end of the

center mark

that gives me my first dimension

now i can add the second dimension

and just as i did before i want to add

the overall length but this time i'm

going to right click

and select the object

and that completes the dimensioning

to print or plot the drawing i need to

move from model space

to paper space so i'm going to select

layout 1

and we can see that there is the drawing

now by going down to the

status bar and clicking on paper

i can access the drawing itself you can

see i'm zooming in and zooming out

i'm going to go to zoom extents to see

all of the drawing

back to paper i'm going to return to

model space

to complete the annotation i'm going to

add some text

multi-line text is available on the

annotate tab it's also available on the

home tab

pan over a little bit select my starting

point

and the other corner of the rectangle

i'm going to add three lines of text

the first one is remove all sharp edges

next one is telling people what the

material is in this case the material is

mild steel

and the third line will be telling

people what the thickness of the

material is

so thickness equals 0.25 inches

click on the closed text editor now

because i've added some more information

i need to go back to my layout 1.

because currently what's viewable in

layout one is only the drawing

so again click on paper zoom extents

and the text is now available

i'm not going to return to model space

and that completes the annotation of

this object
