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.

π Introduction to Tutorial and Circle Command Options
The speaker begins by expressing gratitude for reaching over 200k subscribers and introduces a tutorial focused on AutoCAD commands. The tutorial covers various options for creating circles using different methods: center-radius, center-diameter, two-point, three-point, and tangent to two objects (tan-tan radius). The speaker also demonstrates how to create a circle tangent to two circles and how to create a circle from the outside by specifying tangent points. The tutorial is part of a series, with a link to the complete playlist provided in the video description.
π Exploring Mirror Command and Hatch Patterns
The second paragraph delves into the use of the mirror command in AutoCAD, explaining how to mirror objects across a specified line. The speaker demonstrates the process, including the option to erase the source object after mirroring. Additionally, the tutorial covers the hatch command, which is used to create hatching lines within objects. Various hatch patterns are discussed, including ANSI and architectural patterns, and the speaker shows how to adjust the scale and angle of the hatch lines, as well as how to change the color and transparency of the hatch.
π¨ Customizing Hatch Patterns and Object Visibility
This section continues the discussion on hatching, focusing on customization options such as setting the origin for the hatch pattern, editing existing hatches, and creating solid or gradient hatches. The speaker also explains how to control the hatch area by selecting boundary objects and adjusting island detection settings. Techniques for making hatches transparent and bringing them to the front of other objects are also covered, ensuring that the hatches are visually distinct and properly layered in the drawing.
π Using Object Snap Tracking for Precise Point Location
The fourth paragraph introduces object snap tracking, a feature that helps in locating points relative to other points without creating additional reference objects. The speaker demonstrates how to use object snap tracking to find the center of a rectangle by snapping to midpoints and using the tracking feature to find the exact center point. The tutorial also touches on using object snap tracking for creating projected views from a top view, such as creating a front view by projecting lines and points from the top view.

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
