Q & A

What are the different methods to create a circle in this tutorial?

The tutorial covers various methods to create a circle, including center radius, center diameter, two-point, three-point, tangent-tangent radius, and tangent-tangent-tangent methods.

How do you create a circle using the center diameter method?

To create a circle using the center diameter method, you need to specify the center point, then move your cursor to set the diameter and input the desired value, such as 400.

How can you create a circle passing through two points?

You can create a circle passing through two points by selecting the two-point option, clicking the first point (e.g., the endpoint of a line), and then the second point.

What is the difference between a 'two-point' circle and a 'three-point' circle?

A two-point circle passes through two specified points, while a three-point circle passes through three points, often used for creating circles within polygons like triangles.

How does the 'tangent-tangent radius' method work?

The tangent-tangent radius method allows you to create a circle tangent to two objects, which can be either lines or circles, by specifying the tangent points and inputting the desired radius.

What is the purpose of the mirror command?

The mirror command allows you to create a mirror image of selected objects across a specified mirror line, and you can choose to either keep or erase the original object.

How can you adjust the scale and angle of hatch patterns?

You can adjust the scale of hatch patterns by changing the hatch pattern scale value. To change the angle, specify the desired angle (e.g., 45 degrees for vertical lines).

What are the different hatch patterns available in the tutorial?

The tutorial mentions ANSI hatch patterns, architectural hatch patterns (like brick and concrete), and other patterns such as sand and gravel.

How do you create a gradient hatch and customize its colors?

To create a gradient hatch, select the gradient option, choose the desired colors and patterns, and apply them to the object.

What is object snap tracking and how does it help in drawing?

Object snap tracking allows you to locate points based on the alignment of other reference points without creating additional reference objects, useful for creating centered or aligned objects.

Keywords

💡Circle Command

The Circle Command is a tool used to create circles in design software by defining different parameters such as center point and radius. In the video, multiple methods of creating circles are demonstrated, including center-radius, center-diameter, and passing through two or three points, showing the versatility of this command in different design contexts.

💡Center-Radius Method

The Center-Radius Method is a way to create a circle by first specifying the center point and then defining the radius. This is one of the basic methods shown in the video to generate a circle. The tutorial demonstrates how a user can input the radius value, such as '400,' to create a circle of that dimension.

💡Two-Point Circle

A Two-Point Circle is a method where a circle is created by selecting two points through which the circle passes. In the video, this technique is illustrated by creating a circle that passes through two specific points on different lines, demonstrating how designers can use this method to position circles precisely in relation to other objects.

💡Tan-Tan Radius

The Tan-Tan Radius method creates a circle that is tangent to two objects and has a specific radius. This command is highlighted in the tutorial as a way to create a circle tangent to both a line and a circle, or two circles, and users are shown how to define the radius, such as '400,' to complete the circle.

💡Mirror Command

The Mirror Command is a tool used to create a mirrored copy of an object across a specified axis. The video explains how this command can be used to replicate objects symmetrically on the opposite side of a line, and the option to either keep or delete the original object after mirroring is also covered.

💡Hatch Command

The Hatch Command fills areas with patterns or solid colors, useful for distinguishing sections in designs. In the video, the Hatch Command is used to create patterns like 'ANSI34' inside defined objects. The user is shown how to modify properties like scale, angle, and transparency of the hatch to customize the look of the design.

💡Associative Hatch

Associative Hatch refers to the property where the hatch pattern adjusts automatically when the boundary object changes shape. The video demonstrates how this feature updates the hatch pattern dynamically as the object’s geometry is altered, ensuring consistency in the design.

💡Object Snap Tracking

Object Snap Tracking helps designers locate precise points based on the alignment of other objects without the need for reference lines. The tutorial shows how to use snap tracking to locate the center of a rectangle and create a circle at that point without drawing additional guidelines, emphasizing efficiency in the design process.

💡Gradient Hatch

Gradient Hatch allows designers to fill objects with color gradients rather than solid fills or patterns. In the video, this is demonstrated by selecting color combinations and gradient styles for filling selected areas, showcasing how gradients can be used to add depth and visual appeal to designs.

💡Match Properties

Match Properties is a feature used to apply the same attributes from one object to another. The video explains how this tool can transfer hatch patterns, colors, and other properties between different objects, making it easier for users to maintain consistent styles throughout a project.

Transcripts

At first I would like to thank you all for 200k plus subscribers. This is your

encouragement that made it possible. Let's start with this tutorial. In this

tutorial we are going to learn all the options from the circle command then we

will learn about hatch then mirror and object snap tracking

if you are interested in previous tutorials from this series the link to

complete playlist is given in the description

click on the arrow below the circle command we have already seen how to

create circle using center radius method then next is Center diameter click on it

in this at first we will have to give the center point for the circle click

Center Point then take your cursor away then you will have to specify diameter

of your circle suppose diameter is 400 enter so it will create circle of 400

diameter then next is

two point circle suppose I will create one object suppose I have this line and one

more line

suppose I want to create one circle passing through these two points then

click here and click one two point option then click first point first

point will be end point of this line click there then click on this end point

same way suppose I want to create circle passing through these two points

again click here select two point click on this end point and this end point so

in this way you can create circle passing through two points

and next is three point suppose I will create one triangle

using polygon command I will give number of sides as 3 enter then I will use this

edge method then specify first end point take your cursor away and click suppose

I want to create a circle passing through three midpoints of this triangle

for that click here and click on three point then first point will be the

midpoint of this line click there and click here and click here so in this way

it has created a circle passing through these three points same way you can

create a circle passing through these three points the command you have used

comes automatically on the top if you want to use that command again then

there is no need to click on this arrow we can directly select that command from

here click on three point and select these three end points so in this way

you can use 3-point circle and next is tan-tan radius using tan tan radius you

can create circle tangent to two objects those two objects can be either two

lines two circle or one line and one circle click on it then suppose I want

to create circle tangent to this circle click on the circle and tangent to this

line click on it then you will have to

specify the radius suppose radius is 400 enter so here it has created a circle

tangent to this circle and this line same way you can create circle tangent

to two circles also click on tan tan radius then click on this circle and this

circle then give the radius I will keep 400 as it is press Enter so in this way

it has created circle tangent to these circles now it has

created circle tangent in this way suppose I want tangent circle from

outside like this then for that you will have to specify tangent point in that

particular areas again click on tan tan radius then if we create circle from

outside then that circle will roughly touch in this area so click one point in

this area and other point in this area then specify the radius suppose radius

is 1200 enter so here it has created circle from outside so in this way you

can use tan tan radius command then next is tan tan tan

this will create circle touching three objects those can be three lines three

circles or mix of them click on tan tan tan then suppose I want to create one

circle tangent to this circle click on it this line and this line so it has

created a circle touching these three objects same way suppose I want to

create circle tangent to these three circles click on tan tan tan then click

on this circle this circle and this circle so in this way you can use different

options from circle command then next is mirror command

suppose I want to mirror this object on the opposite side on this side and for

that click on mirror keyboard shortcut for mirror is MI Enter click on mirror

then select object you want to mirror I want to Mirror all these objects and

press ENTER then specify first point of mirror line so I want to mirror it

around this line

therefore take first point of this line so I will take this intersection point

and this intersection point then specify whether you want to erase source object

so here I don't want to erase the source object if you click on yes the

previously selected objects will be erased I don't want to do that therefore

I will click on No so in this way this object has been mirrored around this line

we will try one more time click on mirror then select object you want to

mirror enter then suppose I want to mirror around this line so I will give

here first point then take your cursor below then if you want mirror

line to be straight then you will have to keep this Ortho mode ON then give the

second point and again I don't want to erase source object I will click on

No we will also see what happens if we erase source object suppose again I

will click on mirror then I will select this circle and this circle enter and I

will give this end point as a first point of mirror line I will take my

cursor up to specify second point and for erase source objects I will click

on yes so it has erased the original object and it has kept mirrored objects so

in this way you can use mirror command next command is hatch keyboard shortcut

for hatch is H enter Hatch is useful to create hatching lines if you create any

section click here then at first click here and select your desire hatch

pattern they have provided these ANSI hatch patterns then hatch patterns

starting with AR are the architectural hatch patterns in

architectural there are bricks patterns then concrete

then sand if you scroll down there are different patterns has been given then

there is a gravel so at first I will choose this ANSI34 then take your cursor

inside the object where you want to place the hatch click there

Now here it has created this hatch pattern if you want to increase the gap between

these lines then for that you will have to increase this scale hatch pattern scale

click there and increase it I will make it 5 then press Enter

so here the gap between lines is increase so hatch command is still

running you can click inside as many objects as

you want only ensure that all the objects are visible if some object is not visible

then it will not create the hatch if I try to click here now it is not showing

the preview so in that case you will have to zoom minus and ensure that complete

object is visible then click there then only it will create the hatch and if you

want to reduce the gap then you will have to reduce scale

suppose if I make it 2 so gap will reduce suppose I will keep the 5 value

enter then if you want to change the angle of

the lines here you can specify the desire angle now this angle is

considered as 0 suppose I want to make it vertical then here you will have to

specify angle of 45 and enter so after specifying 45 degree it will make it

vertical and if you want to make it opposite then here you will have to give

the angle of 90 enter then it will create opposite hatch then if you want to

change the color then click here and from here you can choose your desire

color and if you apply some background color then from here you can choose the

background color if you are not happy with the layout of the lines you can set

origin also click on it and suppose I will give origin here so here you can

view that the lines are shifted so just click on set origin and give the origin

so in that way you can shift the pattern also once all your settings are done

then click on close hatch creation so that hatch will be created and if you want to

edit this hatch or if you want to edit existing hatch then take your cursor on

the hatch once it gets highlighted then click on

it so it will bring this hatch editor again then you can make any changes you

want suppose I want to change the hatch pattern to this one so as per that it

has been updated so as I want larger scale I will make it 20. Once you have

done all the changes just click on this tick so it will update your hatch then if

you want to give hatch of single color then for that again click on hatch

and click here scroll it up and click on this solid if you want to fill the

single color click on solid then click the area where you want to create the

hatch and from here you can change the color

suppose I want to create it inside all these objects

and if you want to create hatch by selecting object then for that you will

have to click on this select select boundary objects click on it and

select the object inside which you want to create the hatch now after selecting

this circle it has changed the hatch area now you can control your hatch area

by clicking on these options here right now here outer island detection is

selected therefore it has created hatch for the outer objects

same way if you click on this arrow if you select this normal Island detection

then in this case it will not make any changes but if you have inside loops then

it will give hatch to alternate loops and if you don't want to consider any

objects then click on this ignore Island detection so it will hatch all the

objects then click on okay so in this way here hatch is created and if you

want to bring hatch ahead of these objects then click on this hatch then

right click on it then click on this Draw Order and click on bring to front

so all the objects will go behind your hatch and if you want to make your hatch

transparent then click on this created hatch

and from here you can select your transparency as you make it transparent

the objects below the hatch are visible

click on okay so in this way you can make your hatch transparent also same way

if you want you can give gradient hatch also for a gradient hatch click on this

arrow and click on this gradient then right now our select object is ON so I

will select this object then from here you can select the layout for your

gradient and from here you can choose your desire colors

then from here different patterns are available for gradient you can

choose your desired pattern and click on OK

and if you want to match two hatches suppose here I want this hatch then you

can use match properties take your cursor to properties and click on match

properties then select source object I will select this hatch then for

destination objects I will select this hatch and press Enter so in this way you

can mash hatch using match properties and these hatches has been created as

associative if you click on this hatch you can see here associative option it

is on by default therefore whatever hatches you create those are associative

now what happens because of this associative press escape if you change

the shape as per that your hatch pattern will also change if I click on

this triangle click on this grip and take it up so as per that your hatch is

updated so that is associative press escape now here I have created this hatch

using single hatch command therefore this complete hatch is connected and

single suppose if I want to change this hatch and keep this hatch as it is then

I will have to separate hatches to separate this hatch click on options and

click on separate hatch so each hatch will be individual then click on OK

now here you can select this hatch and you can change its pattern suppose I

want here Honey now it is not visible I will have to increase the scale I will make

it 10 enter and you can change the background color or object color and

click on ok so in this way you can use Hatch command then next is object snap

tracking now object snap tracking is useful to locate points with reference

to other points suppose here I will create one rectangle

now in this rectangle I want to create circle at the center of this rectangle

then normally what I have to do I have to create one line from midpoint of

this line to this line and then at the midpoint of that line I have to create

the circle but using object snap tracking you can locate the center point

without creating any reference objects now for object snap tracking you will

have to keep this object snap tracking ON when it is ON it is visible in blue

color and you will also have to keep this object snap ON then click on this

arrow and you will have to tick the object snap which you want to use for

tracking so if you have all these settings perfetly done then it will work

properly if any one of them is turn off then it will not work

click on circle now the center point will be in the line of this midpoint and

this midpoint so take your cursor to this midpoint don't click there hold it

for some time and take it away you can see that there is green plus sign is

created so it is ready for tracking then take your cursor to this midpoint hold

it for some time take it away so both the points are marked for

tracking then take your cursor in the center so it will locate the center

point click there and give the radius so in this way we can locate the point

using other reference points so this object snap tracking is also very useful

to create projected views suppose this is a top view

and using this top view I want to create front view then how to create that click

on line then take your cursor to this endpoint and take it away and click now

length of this line will be same as length of this line take your cursor to

this endpoint take it above and click then take it above give the length enter

then again take your cursor to this endpoint take it above and click

click on this endpoint enter then press enter to repeat the last command then

this portion take your cursor to this quadrant

take it above click on this intersection point take it above give

the height then again take your cursor to this quadrant take it above click and

now if you click here it will connect it to midpoint so what you can do you can

take your cursor to this midpoint and take your cursor just zoom it take your

cursor to this midpoint and take your cursor on this side now it is tracking

that midpoint click there and press Enter

so in this way you can use object snap tracking for creating projected views so

that's all in the next lecture we will solve some exercises based on what we

learn in this tutorial and after that we will also continue tutorials for civil

interior and electrical engineers so thanks for watching we will stop here
