AutoCAD 2016 Tutorial for Beginners - 3 (Part 1 of 2) Video Lecture - A

in this tutorial we will learn draw
commands we have already seen line
command in the first lecture next
command is polyline polyline is same as
line only it is connected when we create
line
is part of the line is separate whereas
when we create polyline it is a
connected single object we select the
polyline complete object will get
selected it is the only difference
between line and polyline and method to
create polyline is same as line you can
convert simple line into polyline and
polyline into simple line to convert
polyline into simple line you will have
to use the Explorer come on select
Explorer and select the polyline and
press Enter it will be converted into a
simple line and if you want to convert
simple line into polyline then you will
have to use the join command click here
and select join and select all the
object that you want to join the Center
and it will be converted into polyline
or single object you can also assign
thickness to polyline using P edit
command click on modify p8 it-it-it
polyline then select the polyline and
select width here and give the desired
thickness suppose I want point to enter
and press escape in this way you can
give thickness also to polyline then if
object is polyline then it's area
calculation is also very easy if object
is not polyline during area calculation
here to click each and Urey corner to
defend the area but if it is a polyline
you can very easily calculate the area
select utilities' major area then click
on object and select the polyline object
it will show the area and perimeter of
that complete object that is also one of
the benefit of polyline if you want to
calculate area quickly then convert that
complete shape into polyline and you can
very easily calculate the area
then next is circle we are seen circle
by radius method to create circle by
diameter method select this arrow and
click on center diameter give the center
point and give the diameter it will
create the circle with that diameter say
next method is to point circle passing
through two points suppose I have one
object here suppose I want to create one
circle passing through this point and
this point then you can choose the
method of circle passing through two
point give the first point give the
second point it will create circle
passing through two points then passing
through three points suppose I have a
triangle here
and I want to create a circle passing
through these three midpoints and you
can use the three-point method give the
first point second point then third
point in this way you can create circle
passing through three points the NEX is
tan-tan radius that is circle touching
to two objects and up given radius those
two objects can be lined circle or two
circular two lines so as i will create
two circles
I want to create one circle touching to
these two circles of desired radius
click here and select 10 10 radius
select the first circle select second
circle and give the radius it will
create circle touching to those circle
with that much radius then last is tan
tan tan that is circle touching 2 3
objects it can be line or it can be a
circle click on tan tan-tan
then you the first circle second circle
and third circle it will create circle
touch into three objects
the next is arc three-point arc give the
first point make or thof give the second
point give the third point and if we
click on the arrow there are number of
options has been given as per the
available input we can choose the desire
option suppose we will try this one
start center end suppose I have one
shape here I want to create one arc here
for that I will choose this start center
gained now he's asking for the start
point of dark so you have to decide
first point considering that arc will be
created in anti-clockwise direction
therefore this will be my first point
then give the center point and give the
end point so as for it available with
you you can choose the desire option to
create dark or most of times you can
create dark by trimming the circles
and next is rectangle you the first
point gives the second point this is a
freehand rectangle and if you want to
create rectangle with dimensions give
the rectangle command then specify the
first point then you will have to choose
this dimension option click on dimension
and give the length give the width then
give the side and we said you want to
create the rectangle click there same
way you can create rectangle with
fileted corner also for that select the
rectangle command then choose this
filleted option then give the value for
a fill it is to enter then give the
first corner point and give the second
corner point this way you can create a
philately rectangle also but you can
create chamfer rectangle rectangle
choose this chamfer option then use the
chamfer value so was 2x2
to the first point give the second
after creating chamfer rod fileted
rectangle if you want to create normal
rectangle then choose the rectangle
option for that you will have to cancel
the chamfer option for that click on
chamfer and give the distance of zero
zero give the first point give the
second point otherwise it will always
create chamfer rectangle
then if you click on the arrow near the
rectangle command then there is polygon
option is there then you will have to
specify the number of sides for polygon
you can specify minimum three maximum
one zero two four number of sites
suppose I want six numbers enter you
will have to specify the center point of
polygon where you want to create the
center then you will have to choose
whether you want inscribe method or
circumscribed method we will understand
this what is this inscribed and
circumscribed polygon dimension can be
specified in three ways you can specify
its edge length you can specify gap
between two parallel lines that is
distance of face-to-face distance then
you can specify gap between two opposite
corners that is called as corner to
corner distance if you have face-to-face
distance then you will have to use the
circumscribe method and if you have
corner to corner distance then you will
have to use the inscribe method then if
you are is length then you will have to
use the edge map like in your polygon
command good number of side six enter
give the center of polygon a suppose
here we will choose the inscribe in
circle then you will have to specify
radius for circle make or athough
specify radius of circle suppose I will
give radius of four you enter now I have
choosen here inscribe method that means
this distance of four you will be from
the center to the one corner from
utilities we can check it click on
distance and drag the center point and
take to any corner so from center to any
corner will be distance of four you
that means corner to corner distance
will be double that is ten
say me again polygon number of side six
center of polygon lens circumscribed
about circle then again specify the
radius again if I give the radius of
four u then this distance of five you
will be from the center to meet up the
edge will be the distance of fire you
that means face to face distance will be
double that is ten and last method is H
u the polygon command give the number of
pages suppose for you enter then for a
age you don't need to click the centre
point if you want to choose the age
method then don't click Center point if
you click centre point it will go for
inscribed and circumscribed then for age
method you will have to directly click
on this edge option here then you will
have to specify the first end point of
the age then make ortho on then give the
direction where you want to go we can
choose the direction and give the
distance of the edge suppose I will give
for you then this Phi will be the length
of age and in fact this will be the
length of every age as it is a polygon
every age is same in this way you can
use the polygon command
