This set of tutorials will start with Sketcher environment.

So first click on Start Mechanical Design Sketcher.

Then he is showing you the message, select a plane, a planner face or a sketch.

So we will select this horizontal plane, x-pipelene, click on that.

So we are now in Sketcher environment.

So at first we will see this line command, single line command.

So click on line, give the first point and go away from the first point.

So there are two indications are there.

If your line is horizontal, it will show in blue color.

And if it is in line, it will show in white color.

And it is horizontal, it is blue, otherwise it is white.

So directly you can click on the second point.

So your single line is created.

And if you want to give dimension to this line, then you can use the constraint.

Click on constraint.

And line was already selected.

So there is no need to select line again.

Give the location for the dimension.

And if you want to change the dimension, double click on it.

And give the desired value.

And click on OK or press Enter.

So your line of that length will be created.

So this is the one method.

And if your line is not already selected, then you have to select it.

Click on the constraint and click on the line and give the position where you want

the dimension.

So this is the one method.

Suppose we will delete it.

The other method is click on the line, give the first point.

Here you can see length and angle is shown.

So to give this parameter, just press tab on your keyboard.

So here is the length.

Suppose I want it 100 tab.

Suppose I want some angle.

So you can from here, you can give the angle, press Enter.

So your line will be created of that length in that angle.

So here the dimensions are added automatically.

So you don't have to add them using constraint.

You can reposition this dimension by clicking on the dimension and dragging your mouse.

You can place them as you want.

So just drag the arrow and you can place them properly.

So in this way, you can create by taking the dimensions automatically also.

So I will just click it and delete it to remove it.

So in this way, in this two way, you can create the any object in fact.

So using line, you can create single line.

If you want to create a continuous line, you can use the profile.

So click on profile, click on the start point and draw your sketch.

Whatever may be your sketch, you have to draw it.

Continuously you can draw it using profile.

And in profile and you have to adjust the position.

If you want a straight line, it should be blue.

And if it is in the end, it should be white.

So in that way, you can adjust your cursor and click.

And if you want arc, then from here, you can directly create arc inside profile.

You can also create a tangent arc and three point arc.

So click on tangent arc and give the second point.

So once the profile start point, or mate, then it will stop the profile command.

So in this way, you can create the profile.

Then you can give the desired dimensions using constraint option.

Click on the constraint, click on the line and give the position and double click and

give the dimension, whatever you want.

So in this way, you can give the dimension, you can also give the radius to the circle

also.

Constantly click on the circle, go outside, double click and change it.

And again, suppose I give some dimension to this.

And here you can observe that actually, there are two colors right now there.

Green color and white color.

So green color are fully constant objects and white color are under constant object.

So to convert the white into green, you have to give parameters to it.

Suppose I give some parameter to this also.

So this is 35.

So now this has become green.

Because with respect to this 0, we are given its position.

And if we give length to this line, suppose it is 40, then this is also completely constant.

So green means fully constant.

If I add extra dimension to the green profile, then it will become over constant.

If I try to give length of this line, using constraint, then it will become pink.

That means it has been over constant, you are given more parameters than required.

As we have already given the radius to this circle and this length, that means this length

is automatically work out.

So there is no need to give this dimension.

So you can just, and if you want this dimension, then you have to click it.

Then you have to remove one of these two dimensions.

Suppose I don't want this 40.

So just delete it.

It will again become fully constant properly.

So in this way, you have to take care that your sketch should be fully constant.

When you come out of the sketch, suppose we will again select and delete it.

So in this way, you can use the profile.

Then next is circle.

So from here, you can draw circle directly.

Circle, give the center point.

Again, you can give the parameter by pressing the tab directly from the keyboard.

Or you can give it by, you just drag the mouse by clicking on the arrow.

So you can reposition it.

So in this way, you can create the circle.

Suppose I want to create one triangle.

If you want to pan it, just press the scroll button and drag the mouse.

So it will, suppose I want to create a equilateral triangle.

So you can directly use the profile.

Give the start point, second point, then third point and fourth point.

So it will close automatically.

Then give the parameters using constant.

Suppose I want it to be 150.

Then for equilateral triangle, I will need this tool, the angle between these two lines

to be 60.

So to give the angle, you can again use constant.

Constraint, click on the first line, second line and give the position and make it 60

degree.

Same way, here also, I have to give the angle again constraint.

First line, click on first line, click on second line, then click for the position.

Change the angle, 60.

Suppose, so you can by dragging, by clicking on the object, holding the first click and

dragging the mouse, you can position the dimensions, wherever you want it.

Suppose I want a circle touching to these three lines.

And for that, click on this arrow of the circle.

So here, by two methods, you can create it by three point circle method and by try tangent

circle method.

Suppose, if I create it by three point circle, then you have to hover your cursor over the

line.

And you can observe that when I am away from the center midpoint, the two circles are

shown.

When I am at the midpoint, internal circle is filled, circle is there.

That means I am at the midpoint.

If I am away from midpoint or any snap point, then it will show the two empty circles here.

And if I am at the snap point, it will show one circle filled.

That means I have got the midpoint exactly.

So here, to click there, again, here, I want the midpoint.

So internal circle is filled.

Again, I want here midpoint.

So in this way, you can create the object.

Now because of the circle, the object become over constant.

So you can remove this one angle.

So it will become again under or properly constrained.

In this way, you can create a circle or you can undo it.

If you want to cancel, you can undo using control z.

Or there is undo button must be inside here.

Okay, here is the undo.

From here also, you can make the undo selection.

So in this way, you can create a three point circle.

Same way, you can create tritangent circle.

Triangent to three objects.

Recount tritangent.

Click on the object to which the circle is tangent.

Click first object, second object, and third object.

So in this way, it will create tangent to three object.

So in this way, you can create circle using three point.

And you can use regular circle using this circle command.

Give the center point and give the point.

And using constant, give the radius or diameter is there.

Or from here, you can change what you want.

You want radius or diameter that you can indicate here.

Suppose I want 30 radius.

So in this way, it is created.

And suppose I will again remove it.

Just window select it and delete it.

Then suppose I want to create a bite tangent line.

Or suppose I want to create.

You can pan it by holding down the scroll button and dragging the mouse.

Using this axis, you can create axis line, reference lines.

So click on the axis.

Give the first point, give the second point.

Again, I want here one vertical axis.

And I want here one more vertical axis.

And you can give the dimension between these two axis using constraints.

Constraint, click on the constraint.

Click on first axis, second axis and give the position.

Key in the value, press enter.

So these are properly constrained now.

Suppose I want to create a circle.

So circle center point.

So using tab, you can give the value 50.

Here I want to create a circle.

So when you want to create on the intersection of two lines, then you have to take your cursor

at the center.

When both the lines become orange, after that you have to click it.

If you are slightly away from the center point, then only one line will become orange.

And when you will be at the, exactly at the intersection, both lines will become orange.

So click there.

Then using tab, give the parameter.

So in this way, it is properly constrained.

Suppose I want to create one line tangent to these both circles.

So for that, you have to click on this arrow of the line, arrow near to line and click

on this by tangent line.

By tangent line, click on the first circle, click on the second circle.

So in this way, you can create by tangent line tangent to two circles.

Suppose I don't want this object.

So you can remove it by trimming it.

So for that, so trim tool is not visible.

So it must be inside here.

So we will just drag it.

So here is the, the victim tool is there.

Just click there and click on the object to be removed.

So it will automatically remove it.

And if you, any of the tool, if you want to use it again and again.

So for that, you have to double click on that tool and use it.

So you can use it for as many time as you want.

If you double click on that tool.

If you want to zoom it from here also, you can zoom it.

Click on this plus.

And then I don't want this, remove it.

From here, you can fit all in.

So zoom fit.

Using mouse, if you want to zoom it, then you have to press scroll right click and drag

the mouse.

You can directly pan it.

Press scroll right click and drag the mouse.

So in this way, you can zoom using mouse.

So trim is still on.

Just click it.

Then zoom fit.

And if you want to come out of the selected command, just click on it or press escape.

So in that way, you can come out.

So if you want to use any of the command from here also, just double click it.

So you can use it multiple times.

So in this way, you can use the quick trim also.

So we will just delete it.

Suppose I want to create a ellipse.

So for that ellipse command is here, just click on ellipse.

Give the center point.

Then give the horizontal point and vertical point.

So using constant, you can give the parameter.

Click on the ellipse.

So this is horizontal diameter.

Suppose 3 and 2.

And to give the vertical diameter or radius, click on the constant.

Click on H and take this point.

Click here and give the vertical radius.

So in this way, you can create ellipse by giving the parameter.

And suppose if you want to upset some object, suppose I have one line here.

I will create one line here.

And I want to create a parallel line at some distance.

So for that, you can use the opposite command.

So click on this mirror arrow.

Arrow near mirror command.

And click on this offset.

Direct the line and take it to whatever side you want and click there.

And from here, you can give the gap.

What is the gap between these two objects?

So in this way, you can use the offset.

So that's all for today.

Thanks for joining.

In the next tutorial, we will create some exercises based on this learning.

So thank you.
