AutoCAD Ellipse Command Tutorial Complete - Center; Elliptical Arc; Isometric

welcome back in this tutorial we will
learn ellipse command in detail if you
want to give ellipse from keyboard you
have to type e l the keyboard shortcut
is e l press enter and if you want to
you from ribbon bar so here is the
ellipse command center is the first
option click on that give the center
point then make the earth on if it is
not on so right now it is on so no need
to make it on then specify the direction
in which direction you want to specify
the radius suppose i want to specify the
design of azure horizontal direction
then give the radius enter then specify
the vertical radius suppose 10 so in
this way we have created this ellipse
with Holy's horizontal radius of 20 and
vertical radius of 10 so this is the
first method then if we click on the
arrow the second method is axis and that
means at first you will have to give to
end point of the axis and then the
radius of the third axis so we will take
this axis int then specify the first
endpoint of the axis then specify the
second endpoint that means you you will
have to give diameter of the first axis
you can give it vertical also horizontal
also so suppose I want to give it
horizontal and I want diameter to be 30
enter then give the vertical the radius
suppose I want 10 radius so in this way
in this option we are given at first
horizontal diameter first diameter of
the ellipse then radius of the it is
from the center so this is the second
method then in both of these methods
there are one more option is there that
is a rotation option if you give the
first point second point here is the
rotation option is there
that we will see in the in the end
because it needs a great explanation so
before that we will complete this
elliptical arc suppose if you want to
create a arc elliptical art then you can
use this command elliptical arc then for
this command both options are available
that is access end and center if you
want to create the ellipse by specifying
the excess end you can directly click it
and if you want to go for center option
you can click here click here then give
the center point then give the radius
then give the vertical radius then here
to specify make suppose I will make or
thoughts then you will have to specify
start start angle from where you want
so horizontally 0 90 180 270 and 360
suppose I want to start from here
suppose in 120 degree and I want to go
suppose up to 360 degree this 60 now I
want to create a half arc so for that I
will give lip tickle arc then Center
option give the center point then make
ortho on then horizontal it is suppose I
want 15 vertical radius I want 10 then
again I will make orth off then suppose
I want to create half like this from
here to here so here angle will be 90
degree and I want to give I will have to
go up to 270 degree so in this way you
can create a half R then if you want to
ellipse command can also be used for
creating isometric circle actually so
for that actually to create that
isometric circle you will have to make I
so dropped or isometric ducting on by
clicking on this button make the grades
off so when you are after making the
isometric drafting
if we take the ellipse excess and so you
will find that there one more option is
added that is ISO circle so click on
that
give the center point of the circle and
if you want to change the direction in
which direction it should come you will
have to press the f4 button on the
keyboard
so using fi you can change the direction
for the isometric circle and then
specify the radius or you can also
change the direction from here also by
clicking and suppose I want isometric
circle in right direction so click on it
again give the ellipse axis and then
give the specify then select the ISO
circle option then give the center point
and then specify the radius so of their
trade is in there that direction ISO
circle will be created so this is about
ellipse then about the rotation option
so suppose I will again take the center
give the center I will make this off
isometric wrapping off so for that at
first cancel the current come on this
escape then click on it so it it what it
became off then select the center then
give the center point then horizontal
direction make ortho on then radius of
suppose 40 and now I want to specify
second radius by rotation option so
click on rotation now actually it will
create the circle by rotating the circle
around the horizontal axis so suppose if
I want to create a full circle then I
will have to if I give the zero degree
then it will create the full circle and
actually and if I give some other angle
suppose
again I will create Center suppose I
will start it in new terrain nuta
suppose I create one circle ellipse
Center give the center of the ellipse
they are on suppose here is 15 is the
radius and rotation option then suppose
I give rotation angle I will make out
ortho so as I increase the rotation
angle they is interest eccentricity of
the ellipse increases that means higher
the value higher they centricity the
ratio to the minor to major axis will
increase suppose here if I give 45
degree so he Leafs will be created like
this
now what happens exactly exactly in this
rotation that you can understand in 3d
modelling actually so suppose I will
create start one more time and I will
change the workspace to 3d modelling
then now here I will create one circle
so this circle was up and rotate so this
circle was up actually a 15 radius so
what we will do in 3d modelling we will
create one circle of 15 radius then
while creating DC lives we have given 45
degree so here what we will do we will
go to AC isometric then we will rotate
this circle by 45 degree suppose we will
use 3d rotate select the object enter
then I want to do a rotate like grid so
click on this red circle and give the
angle of 45 degree 45 degree so if I
give the top view of this it will look
like as I live so if we see this both
ellipse they will
like the same they will be same or we
can give it in here also tile vertically
if we see that both the ellipse are same
but but one is actually circle rotated
in 3d and one is the ellipse with
rotation option if we further see it if
we see it in suppose other of you
suppose we take it in right view
so here you can view that circle is
rotated at 45 degree and if we view from
the top it it will show like ellipse so
the same concept is used here when we
use the rotation option in ellipse so
that's all so one more thing actually in
ellipse if figure in ninety in the case
of ninety degree what will happen this
circle will get horizontal and ellipse
will not be created so when you try to
create a ellipse by rotation given 90
degree so it will give the error
actually it will suppose we will create
in Ramah suppose here is ellipse Center
center point then radius and here
rotation and if I give the axis rotation
of 90 degree then it will not create the
ellipse because in 90 degree rotation
when you will rotate the circle in 90
degree it will not be visible or it will
be visible as a line therefore in 90
degree it gives the error so in this way
you can use the different options in
reliefs so thanks for giving we will
stop
