Keywords

πŸ’‘Polyline

A polyline is a sequence of straight line segments connected end-to-end to form a single object. In the context of the video, the polyline tool is used to create a connected curve by clicking at different points, which is different from the line tool where each segment is separate. The script illustrates this by showing how a polyline is created by clicking at points and pressing 'enter' to exit, resulting in a single selectable object.

πŸ’‘Dynamic Input

Dynamic Input is a feature in CAD software that allows users to input commands and data directly in the drawing area rather than using the command line. The video script mentions deactivating dynamic input by pressing the F12 function key, which suggests that the user prefers a more traditional approach to CAD commands. This feature is important for users who want to see visual cues and input values directly on the screen while drawing.

πŸ’‘Circle

The circle tool is used to create circular shapes in a drawing. The script explains how to make a circle by specifying a radius or diameter. For instance, the video demonstrates creating a circle with a radius of 100 units and another with a diameter of 100 units, resulting in a radius of 50 units. This tool is fundamental in CAD for creating symmetrical shapes and is used in various contexts within the video's drawing tutorial.

πŸ’‘Arc

An arc is a portion of the circumference of a circle. The video script describes using the arc tool to create three-point arcs, which are defined by specifying the first, second, and third points. Arcs are essential in CAD for creating curved elements in a drawing and can be used to form parts of circles or other circular segments. The video emphasizes the versatility of the arc tool, depending on the workflow and the specific requirements of the drawing.

πŸ’‘Rectangle

A rectangle is a quadrilateral with all angles equal to 90 degrees. In the video, the rectangle tool is used to create rectangles by clicking at two points or by specifying the length and width. The script provides an example of making a rectangle with a length of 100 units and a width of 50 units using dynamic input for precision. Rectangles are commonly used in CAD for laying out architectural plans and structural elements.

πŸ’‘Pan

The pan tool allows users to move the view within the drawing area without affecting the objects in the drawing. The script mentions using the pan tool by pressing and holding the mouse wheel to navigate around the drawing. This tool is crucial for navigating large drawings or for repositioning the view to focus on specific areas of the design.

πŸ’‘Move

The move command is used to relocate objects within a drawing. The video script illustrates how to use the move tool to select an object, specify a base point, and then move it to a new location. This is demonstrated with the circle and rectangle objects, showing how they can be moved to different positions in the drawing. The move command is essential for adjusting the layout and position of elements in a CAD drawing.

πŸ’‘Copy

The copy command is used to duplicate objects in a drawing. The script explains how to use the copy tool to create multiple copies of an object by selecting the object, specifying a base point, and then clicking at points to place the copies. This is shown with the circle object, where the user creates multiple copies by clicking at different points. The copy command is vital for creating repetitive elements in a design without redrawing them.

πŸ’‘Rotate

The rotate command is used to change the orientation of an object by a specified angle around a base point. In the video, the rotate tool is used to rotate a rectangle by 30 degrees. The script describes selecting the rotate tool, choosing the object, specifying the base point, and then entering the rotation angle. This command is essential for aligning objects or creating variations in a design.

πŸ’‘Mirror

The mirror command is used to create a symmetrical copy of an object across a specified line. The video script demonstrates using the mirror tool to create a mirror image of a rectangle and a circle across a line. The user selects the objects, presses enter, and then clicks two points to define the mirroring line. This tool is crucial for creating symmetrical elements in a drawing, which is common in architectural and engineering designs.

πŸ’‘Trim

The trim command is used to remove unwanted parts of objects that extend beyond other objects. The script explains how to use the trim tool to trim a line up to the next boundary by selecting the trim command, pressing enter, and then clicking on the part of the line to be trimmed. This is shown with intersecting lines and a circle, where the user trims the lines to create a clean intersection. The trim command is essential for refining drawings by removing excess lines and shapes.

πŸ’‘Offset

The offset command is used to create a parallel copy of an object at a specified distance. In the video, the offset tool is used to create offsets of a rectangle and a line at distances of 2 units and 10 units, respectively. The script describes typing the offset distance and selecting the object to create the offset. This command is crucial for creating parallel lines or shapes in a drawing, which is common in drafting practices.

πŸ’‘Object Snap

Object Snap (OSNAP) is a feature that allows users to snap the cursor to precise points on objects, such as endpoints, midpoints, or intersections. The script mentions activating object snap for precise drawings and provides examples of snapping to endpoints and midpoints. The video emphasizes the importance of object snap for accurate drafting, as it ensures that objects are positioned correctly relative to each other.

Transcripts

play00:00

so now you are familiar with the basic

play00:03

workflow of making a line using

play00:06

different tools we'll move on to learn

play00:08

about different draw and modify tools

play00:10

and then we'll make a simple drawing

play00:12

using those tools so you already know

play00:15

about line let's talk about polyline so

play00:18

I'll go to polyline and as you can see I

play00:20

have the dynamic input active which I

play00:22

prefer to keep deactivated so I'll press

play00:25

f12 function key and it will be

play00:27

deactivated like this and now I'll click

play00:30

at a point the next next next and so on

play00:32

and enter to exit this command so this

play00:37

one is polyline let's go to line again

play00:39

and once again I'll do the same and we

play00:42

have the line here so the basic

play00:44

difference between these two tools is if

play00:46

you select polyline the complete set of

play00:48

lines will be selected as this one is a

play00:51

connected curve but not in case of line

play00:53

if you select line only that particular

play00:56

segment will be selected and all of

play00:58

these are separate so that's the first

play01:01

and the basic difference between line

play01:02

and polyline tool so I'll select them

play01:05

and I'll delete both the drawings now to

play01:08

make the circle you can select the

play01:10

circle tool then click at a point and

play01:13

now type in the radius value so I'll

play01:16

type 100 as the radius and I'll press

play01:19

Enter and here we have it so we have the

play01:21

circle of radius 100 unit you can also

play01:24

type in the diameter so I'll go to

play01:26

circle again I'll click at a point and

play01:28

now instead of radius I will go to the

play01:31

command line and I'll click on this

play01:33

diameter and now AutoCAD will prompt for

play01:36

the diameter value so if I type hundred

play01:38

now it will make a circle of radius 50

play01:41

or die a hundred and here we'll have the

play01:45

circle of die a hundred now similarly we

play01:48

have the arc tool now using arc tool you

play01:51

can make three point arts using first

play01:54

second and third point and also there

play01:56

are other features which you can use to

play01:58

make different kind of arcs and it just

play02:01

depends on the kind of workflow and the

play02:03

drawing that you have and depending upon

play02:06

that you can select from any of these

play02:07

are tools similarly for the circle we

play02:10

have six different ways of making circle

play02:12

and it will just depend on your

play02:14

workflow and depending on that you can

play02:17

select the type of circle that you need

play02:18

now let's move to the rectangle tool so

play02:22

using rectangle tool you can obviously

play02:24

make a rectangle in this case click at a

play02:26

point and then click at second point and

play02:29

you'll have your rectangle the first

play02:31

point and second point now this one is

play02:33

obviously not a precise way of making

play02:35

rectangle so if you want to make it

play02:37

precise then activate the dynamic input

play02:40

by pressing f12 and go to rectangle so

play02:44

that we have this tooltip now and click

play02:47

at a point and now type in the length

play02:50

and width so I'll type 100 for the

play02:52

length and then I'll press tab key and

play02:55

I'll type 50 for the width and I'll

play02:58

press Enter

play02:59

and here we have it so the length is 100

play03:01

and the width is 50 and that's the

play03:04

rectangle which we need now you can move

play03:08

your complete drawing area using pan

play03:10

tool as you know that just press and

play03:12

hold your mouse wheel and pan it around

play03:14

but what if you want to move only

play03:16

selected drawings for example if you

play03:20

only want to move this circle then you

play03:22

can use the tool right here on the

play03:24

modify panel called move select move

play03:27

tool now select the object that you want

play03:30

to move and press Enter now select the

play03:33

center or any other point if you want

play03:36

and then move it to your desired point

play03:39

so click let go then again click and it

play03:43

will move it I'll do it again so I'll go

play03:45

to move then I'll select this circle or

play03:48

maybe let's select multiple objects so

play03:50

I'll select this rectangle and the

play03:52

circle I'll press ENTER and now you need

play03:55

to start from a point so I'll click at a

play03:57

point maybe here randomly and it will

play04:00

pick your objects from that point now

play04:02

click at the next point where you want

play04:04

to drop it there we have it now the copy

play04:08

command works in a similar way but in

play04:09

this case instead of moving the object

play04:12

it will create copies so I'll go to copy

play04:14

I'll select the circle and I'll press

play04:17

Enter

play04:18

now I'll select the center of this

play04:20

circle for picking this and now look at

play04:23

this we still have the original object

play04:25

but now a new copy is also made

play04:28

now click at this next point next point

play04:31

and you'll have multiple copies of the

play04:33

same object now to exit this command

play04:36

press Escape key so I'm gonna now select

play04:40

all of these things that we don't need

play04:42

and I'll delete them all so I'll

play04:45

deactivate this dynamic input using this

play04:48

status bar you can also deactivate it

play04:50

using f12 function key we will now work

play04:54

with simple drawing here now let's talk

play04:57

about rotate command so here we have the

play05:00

rotate tool now select the rotate tool

play05:03

and select the object that you want to

play05:05

rotate now I'll press ENTER and the

play05:08

command line will prompt you to specify

play05:09

the base point whenever you are in doubt

play05:12

remember you don't know the next set of

play05:13

steps look at the command line it will

play05:15

always prompt you with the next set of

play05:17

steps so in this case you need to

play05:19

specify the base point so I'll select

play05:22

this one is the base point and now your

play05:25

object will start rotating along that

play05:28

base point now look at the command line

play05:30

it is prompting you to specify the

play05:33

rotation angle so let's type 30 and

play05:36

enter and look at this so now the

play05:38

rectangle is rotated to an angle of 30

play05:41

degrees with respect to the original

play05:43

rectangle it was horizontal it's now 30

play05:46

degrees with respect to that now let's

play05:48

add a circle inside this rectangle

play05:51

somewhere here and also I'll make a

play05:55

straight line here like this all right

play05:58

and I will talk about the mirror tool

play06:00

which is right here

play06:02

so using mirror tool you can make a

play06:05

mirror image of any object in this case

play06:07

I'll select this rectangle and the

play06:09

circle I'll press Enter and now you need

play06:12

to specify a mirroring line so mirroring

play06:15

line in this case is this one this line

play06:17

so I'll click on this point and then

play06:20

this point and we'll have this kind of

play06:23

mirror image so using mirror tool you

play06:27

can make mirror images like this so

play06:29

press ENTER to finish the command and

play06:30

you'll end up with mirror image of this

play06:32

original object where this was the

play06:35

mirroring line so mirroring line is not

play06:38

always necessary you can even make

play06:41

mirrors

play06:41

without the mirroring line so I'll go to

play06:43

mirror I'll select these two objects

play06:45

press ENTER and now I'll randomly click

play06:48

at two points maybe you can make it

play06:50

aligned if you want like this but I'll

play06:53

just make a straight lines and I'll

play06:55

press ENTER and we'll still have the

play06:58

mirrored copies now let's talk about

play07:00

fill its so we have a tool here called

play07:04

fill it and using fill it you can make

play07:06

the corners of any sharp drawing rounded

play07:10

so I go to fill it and now I'll go to

play07:15

radius and now I'll specify the radius

play07:19

as let's say 5 unit and enter now I'll

play07:24

click on this line and this line and

play07:28

look at this a small radius of 5 unit

play07:31

will be applied let's do it again so

play07:33

I'll go to fill it and now I'll click on

play07:36

this radius option and type in the

play07:38

radius value in this case I'll type a

play07:40

bigger value maybe 12 unit and enter and

play07:43

now select the first line and the second

play07:47

line and you'll have this kind of fill

play07:48

it now let's make a line that intersects

play07:52

these objects like this and now we'll

play07:58

talk about the trim tool so like this so

play08:04

we have a lot of intersecting curves

play08:05

here and now if you want to trim some

play08:08

unwanted geometries for example if you

play08:10

want to trim this part of the line or

play08:12

this part you can use the trim tool

play08:14

right here so I'll go to trim and now

play08:18

after selecting trim just press Enter

play08:21

key this is a step which you are most

play08:24

likely to forget so in this case select

play08:26

trim and then press Enter

play08:27

don't forget to press Enter key right

play08:30

after selecting the trim tool now click

play08:33

on the part of the drawing that you want

play08:35

to trim so in this case I'll click on

play08:37

this line and look at this it will trim

play08:38

it up to the next boundary if I click

play08:41

here it will trim it up to the next

play08:42

boundary the similar thing will happen

play08:45

for the circle as well if I click here

play08:47

it will trim it up to the next

play08:48

boundaries so using trim tool you can

play08:52

trim the objects up to

play08:55

next available boundaries like this

play08:58

that's a trim tool now finally let's

play09:02

talk about a tool called offset so I'll

play09:06

go to rectangle and I'll add a Filat of

play09:11

radius 10 on this corner and I'll press

play09:18

Enter

play09:18

pressing enter we'll just repeat your

play09:20

last command and I'll select this one

play09:23

okay there we have it now I'll go to

play09:25

offset and offset tool we'll make

play09:28

another copy of your object which is

play09:31

geometrically similar but at a certain

play09:34

distance so now I'll type in offset

play09:37

distance of let's say 2 unit I'll press

play09:39

ENTER now I'll select this boundary and

play09:42

I'll move it outwards so if I click

play09:45

inside it will make an offset copy just

play09:47

inside if I move outside it will make

play09:49

the offset copy outside just like this

play09:52

again I'll go to offset and this time

play09:55

I'll add a bigger value of let's say 10

play09:56

unit for the offset distance I'll select

play09:59

the same line I'll click outside and

play10:01

look at this we have this offset again

play10:03

so that's where officer tool now let's

play10:06

talk about the object snap status bar

play10:09

option which is a really important

play10:12

status bar option and without using

play10:14

object snap you won't be able to make

play10:16

precise drawings so whenever you select

play10:19

any command and move your cursor close

play10:21

to any point for example in this case

play10:24

I'm moving close to these intersection

play10:26

points also called the end point or a

play10:28

cat or a matically snap your cursor to

play10:31

those points and you'll also see this

play10:32

tooltip with end point and this green

play10:35

box so this is happening because we have

play10:39

object snap activated here and on the

play10:42

object snap if you click on this arrow

play10:44

you'll see list of points which Orica

play10:47

add recognizes and from this list we

play10:50

have endpoint midpoint Center

play10:52

intersection and insertion selected so

play10:55

currently only these points will show up

play10:57

when you bring your cursor close to any

play10:59

point in this case look at the midpoint

play11:02

it is now chaired I'll just uncheck this

play11:05

now I'll go to this point we

play11:08

have in point here and I'll just click

play11:11

here and now I'll move my cursor close

play11:13

to the midpoint of this line this line

play11:16

but look at this we don't have anything

play11:17

now even if I click here which is very

play11:20

close to the midpoint look at my drawing

play11:23

it will snap the line to this point

play11:25

because this was highlighted it won't

play11:27

snap to midpoint now I'll press ctrl-z

play11:30

and I'll go to this object snap arrow

play11:33

and I'll activate midpoint also make

play11:37

sure that this tool is also active here

play11:39

on your status bar this should be

play11:42

checked now if I go to midpoint look at

play11:46

this it will be highlighted and if we

play11:47

show the midpoint so now we can clearly

play11:49

click like this so this is the object

play11:53

snap now other points in object snap

play11:57

include the center if I move close to

play11:59

the center of an arc or circle it will

play12:02

recognize that other points are the

play12:04

intersection point for example if I go

play12:06

here it will recognize the intersection

play12:08

of these two lines or any other curve

play12:10

and so on if you deactivate object snap

play12:14

you won't be able to snap to these

play12:16

points and look at this even if I move

play12:18

close to this point it won't recognize

play12:20

it no end points no mid points so it

play12:23

should be checked if you want these

play12:25

points so now we are fairly equipped

play12:28

with the basic draw and modify commands

play12:31

of ArchiCAD and using these tools will

play12:33

now make our 2d drawing so this is what

play12:38

we are going to make so this drawing

play12:40

here in our CAD so for this drawing I

play12:44

will start with the line tool so I'll go

play12:46

to line and I'll click at a point and

play12:49

now I'll make a line of length 18 unit

play12:51

which is this one 18 unit so 18 and

play12:55

enter and enter again now look at this

play12:58

line it's kind of very tiny so I'll zoom

play13:00

in to bring it here in the drawing area

play13:02

now we see it clearly so now I'll go to

play13:05

circle and I'll make all these circles

play13:09

so Dyer 8.2 daya 4.8 daya 3.6 let's

play13:14

start with the first one and AutoCAD is

play13:17

prompting you to specify radius but we

play13:19

need daya so I'll go to diameter and I

play13:22

type 8.2 obviously you can directly type

play13:24

4.1 if you know the radius you can just

play13:27

type in but in this case I'll do that

play13:28

I'll type the Daiya now again I'll press

play13:30

ENTER and this will repeat the last

play13:32

command so I'll go to Center once again

play13:36

I'll click on diameter and I'll type 4.8

play13:40

enter enter again the same center again

play13:45

diameter and 3.6 all right so we have

play13:49

the three circles now we'll also make

play13:52

this circle this circle of five point

play13:54

seven although this one is a small arc

play13:56

but just imagine that we have a complete

play13:59

circle we'll trim off everything that is

play14:01

not necessary so I'll go to circle the

play14:04

same Center and this time we need to

play14:07

type in radius so five point seven and

play14:10

enter okay we are done now look at this

play14:14

total gap it is twelve and half of this

play14:18

should be six so we have the central

play14:21

line we can make an offset on this side

play14:23

as well as on this side with a distance

play14:26

of six unit so I'll go to offset now

play14:28

I'll type in six and enter and now I'll

play14:32

make an offset here on this side to the

play14:36

left another one to the right all right

play14:39

now we need to make another offset as

play14:42

you can see this line is tangent on this

play14:44

circle so is this so that means this

play14:47

line is at a distance of the radius of

play14:49

this circle so it's radius is four point

play14:52

one as diameter is eight point two so

play14:55

distance between this line and this line

play14:56

should be four point one so let's go to

play14:59

another offset offset four point one

play15:02

enter this line to the left this line to

play15:07

the right we are done now let's go to

play15:11

line tool again I'll go to this point

play15:14

I'll make this line and I'll press

play15:19

Escape key now this gap is one unit as

play15:23

you can see here so again I'll go to

play15:24

offset one enter this line and I'll

play15:31

click upwards now this gap is full unit

play15:35

from this

play15:35

lines again we'll make another offset so

play15:39

offset for enter this line and to the

play15:46

top now the center of these circles are

play15:49

at a distance of 2.5 and it's

play15:51

intersected by this line

play15:53

so this line and this line so that's the

play15:56

intersection point where the center is

play15:57

so again I'll go to offset and I'll make

play16:00

a line here which we don't see will

play16:03

later on delete this line but for now we

play16:05

need to make it so I'll just go to

play16:06

offset and this distance is 2.5 so 2.5

play16:10

and this line to the top alright so we

play16:16

have four of these lines and we have lot

play16:19

of lines here which are completely not

play16:21

necessary so we need to clean up our

play16:23

drawing a little bit so let's first

play16:27

delete this line the line in the center

play16:29

we don't need it and now I'll go to trim

play16:33

and I'll press ENTER so now we don't

play16:37

need this line we don't need this line

play16:39

all right it's cleaned also we don't

play16:42

need this part of the line and this part

play16:44

of the line we also don't need many of

play16:47

these things but we'll delete those

play16:48

drawings later on for now I'll press

play16:51

escape and now I'll add these circular

play16:53

portions using Filat as you can see the

play16:56

fill it radius is 1.6 so I'll use this

play16:59

and go to Follette now I'll select

play17:02

radius and I'll type in 1.6 for the

play17:06

radius now I'll select this line and

play17:09

I'll click right here and the fill it is

play17:12

added but unfortunately we don't have

play17:15

the line here anymore so I'll go to line

play17:17

and I'll just make one line like this

play17:20

I'll just touch it here that's enough so

play17:22

I'll go to fill it and once again radius

play17:26

it should be 1.6 and this line and this

play17:33

line all right so we have it now we need

play17:37

to make our circles so again for making

play17:41

circle we don't have the intersection

play17:43

point for that I'll go to line I'll

play17:46

click on this point here and Alex

play17:48

ended up to this point so that we have

play17:50

the intersection I'll go to circle I'll

play17:54

select this Center now the radius of

play17:57

circle is 1.5 - well that's the diameter

play18:00

and the second one is 2.4 let's use

play18:03

these values so I will go to diameter

play18:05

1.5 2 and press ENTER again the same

play18:10

Center and this time the diameter is 2.4

play18:13

so dire 2.4 and enter all right now we

play18:18

can delete this line and this line as

play18:20

well these two where the reference lines

play18:23

they are no longer needed now we need

play18:25

the same kind of circle here but instead

play18:27

of making it I'll make the mirror image

play18:30

so I'll go to mirror I'll select these

play18:34

two circles and enter and now I'll click

play18:38

on this midpoint and then on this

play18:40

midpoint for the mirroring line and I'll

play18:43

press Enter and we'll have the mirror

play18:45

image like this so as you can see we are

play18:48

approaching very close to the end result

play18:52

so before we do that let's trim this

play18:54

extra part I'll go to trim enter I'll

play18:58

trim this part so that we have a clean

play19:00

picture here of what we need to make and

play19:02

we just need to make this part of the

play19:04

drawing which we can easily make using

play19:07

offset so I'll go to offset again and

play19:10

now this offset is 1.6 as you can see

play19:13

here so let's type that 1.6 I'll select

play19:17

this line I'll click to the left I'll

play19:19

select this line click to the right now

play19:22

this is 4.8 so I'll go to offset again

play19:25

and distance is 4.8 enter now this line

play19:30

is offset at a distance of 4.8 now all

play19:34

we need to do is just trim that's it so

play19:39

I'll go to trim enter and I'll trim this

play19:44

this this part this part this part this

play19:49

tiny part right here and this tiny part

play19:54

right here and this part of the drawing

play19:56

and I'll delete all of these extra lines

play19:59

so I'll select these lines these lines

play20:02

and these two and I'll delete them and

play20:05

this is our end result so now you can

play20:08

clearly see how we use these tools in a

play20:11

practical situation like this to make

play20:13

our drawings in our CAD so in the last

play20:16

video we'll talk about managing our

play20:18

drawing adding symbols and plotting of a

play20:21

drawing
