Welcome back in this tutorial we will create one sketcher object based on what we learn

in previous lecture.

So we will be creating this object click on start mechanical design sketcher, okay click

on the plane.

So at first we will create these three circles, circle center point, give the radius.

Just double click to repeat the circle command multiple times.

Then give the places skip, give the parameters in constraint.

So first is 23, 31, 40, give it 23, constraint 31 and then last is 40.

Back there oh.

So these three circles are created.

So one is reference circle, so you will convert it into reference object, click the circle

and click on this construction standard element.

So it will convert it into reference object.

Then suppose I want to create this area of circle, so at first I will have to create

a circle of diya 10.

So again circle, take the point.

Now this circle is coming as a reference object, so click here.

So it will be created as a regular object, standard object and give the radius.

So diya 10, fire radius.

Then we want to create a polar array, so select this object then click on this arrow from

here select rotate.

Then give the, click on rotate.

Then give the number of instance as a six.

Then give the best point and give the angle, angle is 60 degree, 360 divided by 6, 60

degree.

So in this way this polar array is created.

Then next we will be the circle at 60 degree.

So we will create one axis and one horizontal axis.

Again one more above.

And then we will give the constraint from this axis to h, it is 60, double click and change

the dimension.

Click on constraint from this axis to this axis is 60, double click.

Then next is circle, circle of radius 18, outside circle is radius 18, inside circle is

diya 22, so create the circle.

Then both lines color changes to orange, click on the point, so it will exactly catch

the intersection point.

Create first circle, give the radius, so internal circle it is 22 diya, that is elia

radius.

Then again circle, take care that it don't take any other constraint.

Otherwise it will not, we will not able to dimension it properly.

Then outside circle is 18, give the 18.

So these two circles are created, so I want these two circles to be here.

So just press control and say it both the circle, then click here, click on last layer.

Then if duplicate mode is not selected, select it, give the number of instances to be

1, give the best point, or you can give the best point and give the second point.

So in this way you can copy it, then next is to create this circle, of radius 100, again

create the circle, give constraint radius 100, then just drag it and place it here.

Then press control and select this two object, click on constant, define in dialogue box and

make it tangency.

Again here, control and select both the object, constraint defined in dialogue box, tangency.

Okay now the center point is not properly aligned with this line, the parameters are not

properly defined, therefore it got shifted.

So what we can do, we can select this center and this vertical axis, again click on constraint

defined in dialogue box and click on this coincidence, so it will get attached to it

and also give the parameter to the circle.

So this is outside circle is of 18 radius and inside is of 11 radius, constraint, inside

is 11 is correct.

And again this point should coincide with this line, so again select the center, control

select this horizontal line, again constraint defined in dialogue box, coincidence.

So it is now fully defined.

Then I don't want it external circle, so just click on this arrow and select quick

trim or just double click it, so you don't have to click again and again on that toolbar,

double click and remove the unwanted objects.

So again click it to cancel it.

Then this portion is ready, and next is these two circles, 8 radius.

So again take the circle, give the center point and touch it, so it will automatically

become tangent and on other side we will create it manually tangent, constraint, tangency.

And parameter radius is 8.

Then I don't want this external half selected, then I want it to be below also, so we can mirror

it, select that arc, then click on this arrow mirror, then I will have to create one

horizontal axis for that, so just create one horizontal axis, then select the object mirror,

click on the horizontal axis, so it has been mirror there.

Then next is these two circles, so for that again we will create one vertical axis, then

we will give the parameter between this vertical and this vertical axis, so it is 46, so we will

give it 46, then we want a circle of 8 and 15, so we will create two circles, and it becomes

orange, click there, so this is the first, this is the, don't take any constraint otherwise

it will not, we will not able to add parameters to it, so click on constraint, so outside

is 15, outside is 15 inside is 8, so just give it 15 and inside is 8, so this is created,

then next is this 8 radius circle again, so circle tangent it to this circle while drawing

it, then hold control and select this two object and make them tangent using constraint

different in dialog box, give the parameter of 8, then just trim it, zoom, you have to press

scroll right click and drag the mouse to screw, to zoom using mouse, then mirror it below,

so again click on mirror, select the object, select the axis, so it will be mirror around

that axis, then we can just double click on the quick trim and remove the unwanted object,

so again we don't want this circle also, and just

ok, so we will trim it also, so trim is already running, zoom it,

so in this way now it is ready, so we will stop here, thank you,
