Hello all today, it's going to be a continuation of the previous session that is two dimensional sketching. All right, I welcome you on to the tutorial. So I'm just going to click on new. I'm just going to create my SketchUp. I'm just going to select my randomly. I just have a random plane.

So the sketch that we're going to do today, this is an arbitrary space and it has all the dimensions here. So just for a quick view, we just look at the dimensions and everything that you see the values here, right, so these are the dimension constraints, and whatever you see here, the symbol So these symbols are nothing but the geometric constraints. So let's go ahead and try to draw the sketch. So whenever you draw a sketch focus on the major outline, so the basic outline of the sketch. So first let's try to create this, how to sketch. So let me start over the Bs 110.5 the circular distro line.

Let me switch off the continuous auto dimensioning so that we can learn it a little more better. So, I first have this line here, and I'm going to draw another line and store off Figure about this, okay? And you see this display is lines for this reason basically shows like, where exactly this point meets up with the other point, okay? So that's a really good option and just click here. So now we have the base, the basic profile. So here we need, this particular baseline got this article is covered.

And let's try to make this the middle of this particular y axis, the vertical axis, okay, so for that I'm going to use geometric constraint and the sharp geometric constraint and see. I'm going to click on the midpoint constraint, and always ensure who's checked on click on this line, select the vertical constraint Okay, so now this is constrained. Let me do the same thing even with this. So even that is in the center, okay? So my point is click on the line, just select line, that's all there, okay. So now what is the dimension you 110.5 and 77.5.

So just hit on D four dimensional constraint. Select our input in just select this point and select this point and just drag it up. Just do model. So this is fine. This is so just double click on this Then you can change the value 105 awesome. This one will be 7.5 and you can use Ctrl F for fit or you have the option here.

Okay, so now if you see here it looks a little shorter you so let's check why exactly it is so we need to check the other dimensions. So let's give this length the overall them 130.8 okay select this just going to zoom out a little place Good point. Okay. That sounds good. So looks like it's still moving because we are not given to the meaning dimensions. So, first we need to align this with give a dimension with respect to the horizontal and the vertical around.

So this vertical thing is covered. If you notice, I will not be able to move this particular thing even more this line, okay? This is because this dimension is only given the horizontal dimension, okay. And, um, cuz I've only given a midpoint constraint to this. So now what I need to do is I'm going to give this particular dimension So with respect to the sketch horizontal axis item, I need to give this dimension or this time anyone would do because you already defined the length length, you So open dimension constraint again rep dimension, and I just select infer and to select this on this one. Okay, so let me just give this something like 20.

Okay, in case I want a geometrical constraint, okay, I just hit Ctrl C Ctrl Z. Alright. And what I'm going to do is I'm just going to choose geometric constraint, and I'm going to use can use collinear. And I just select this line, I just place it on the sketch horizontal axis, okay. And so here and it's always better when you do it with respect to keeping it on the origin line, or at least at the midpoint, exactly. So, so when you do the sketches that it will be really easy for you. Okay.

So now putties catch needs to constraints. Let's Located. So like I mentioned in my previous class, the easiest way to find out is practice, okay? So you'll be able to practice that's the reason it says to constraint because its length is not defined as you can define by the length, or you can define it with an angle. Okay? So let's see if there is a length in the diagram who is curative at 77?

Okay, so it's mentioned as equal and that equal equally simple. So I'm just going to define one here again, so that is 77. And now what I'm going to do is I'm going to check for the geometric constraint, okay, so I'm just going to use the equality Lesson. I want Finland testers. Okay? So I'm just gonna select both of them.

Okay, so now we have equality concern. And so sketches for the constraint, okay, so let's add the remaining feature. So we have a base profile now. Okay. And now let's try to add the other features. So we have one profile here and this one profile you Okay, so let's do this profile first this rectangle that you see, okay, so it says 28.5 and these both are like equal length.

And they also given us the height that is 35. So rectangle 20.5 across 35. Okay, just zoomed out. Let me select a rectangle. So choose the first method it's by two points. So just a random rectangle.

Okay. First thing what I'm going to do is I'm going to geometrically constrain it. Keep the midpoint selectors and select the vertical axis. Okay, so now it's at the midpoint. And now what I'm going to do is I'm just going to define the height and the length. How old are you smile and double click and change the values 28.5 Okay.

And then next value that we have is 35. Okay. So now what we need to do is to check the drawing. So if you see this 35 begins from the top of the line, right? So what are you going to do to try to make that particular line collinear with this particular, okay? The baseline, so if the geometry constraint again, select the collinear line and select this line selectors.

Okay, so now it lies. All right. And so here's a new command that I'm going to teach you and that is nothing but trim, and the shortcut would be D. And if you want to look for the option if you go to fix pandas, and you will see this edit corruption. So under the Edit curve, you have like a lot of adoption of chamfer select quick trim, quick extend, make corner. So we'll discuss all these options one by one as in when we progress from scratch. So now I'm going to use quick trim which is a very easy to okay.

So you can either select this, just select this line, it will give you a quick pick option, okay? There are two lines because the previous line as well as the new rectangle, okay? So just select this and now we have this particular thing. Okay. So it says the sketch needs three constraints. So I hope you're able to guess like, which is that the correct doodle which one is got deleted?

Let me do the controls and show that to you. Do you see this, like two dimensions which are there? So 28.5 was a dimension of this particular thing. So when I deleted this line, this car deleted, okay. So that's why it's always advisable always do the geometrical constraint first and then do the dimension constraint. Okay, so the problem, so let's try to trim this again.

And, and we're trimming notches so you can click it. You can even drag this person drag it. So you just draw a line and the Lines deleted. Okay so now let's our dimension this high dimensional constraint D. So you will infer constraints select points or because you select input you can even click on the line and drag it you will get your dimensions okay. So this one will be 28 point fan and now your sketch says it still needs like two constraints. So let's see which constraint is that?

So, you see this so the top thing is gone. So basically the vertical constraints, okay, so what I'm going to do is first thing let me just give an equal equal constraint, okay, equivalent okay. So sketch needs one more constraint, all right, under one constraint is nothing but your What did you constrain? Okay, so The vertical constraint is this one, okay? So just select vertical, this click on any one and select this line. So, so for this one select vertical constraint, okay.

So you see allow people to move this to the side and not be able to do the same, okay? So sketch needs one constraint. So let's find out which constraint that is. So and if you notice this particular line has a midpoint constraint, but how if you remember, we had given a midpoint constraint for the top line, and when we trimmed out that line, that particular midpoint constraint also got deleted. Okay, so you need to be really watchful when you're working with the dimensions. And so what I'm going to do right now is that I don't need a midpoint here because there's no line here, okay?

And I'll be able to drag this tiny to fix this right. So I can fix this by giving you the same dimension to this one as this one. So for this one lines, they don't have to give a dimension constraint. So I'll just select the equal n, okay? And I'm just going to select both the lines. And that will make it fully constrained.

All right. And so are we close enough to this sketch? Let's check Okay, we achieved this, this profile is achieved, okay, coming to this profile. So what is this is a semicircle. So what we can do is we can just draw a circle and what will be the radius. So, if you see that this will be the diameter from here to here, this point, okay, so that is 64.4, that will be a diameter.

So let's draw that. And let's see from where it's starting, it's starting somewhere from the axis. So, I'm not going to do it from the axis. So if you want, we can still do it from the axis. So let me show you how to do that as well. So you would understand in case you go wrong as well, right?

So you would be able to correct Okay, so what I'm going to do is I'm just going to Delete this particular constraint, okay, right click select from list, this collinear constraint, okay, select and delete it. Okay, so now I have one constraint left so basically are given a dragon. So I'm just going to define the height first and the height is 28. Okay. Select dimension constraint, just going to be a height Okay, and now it's fully constrained. Let's try to draw the circle of diameter 64.4 from the center of the circle by center point itself center diameter, this select the center and the diameter is 64.4.

Okay, Now this is a picture I have added. So we achieved it. So now what I'm going to do is I need this particular line. And I don't want this line, right. So first of all, before I trim this, I'll not be able to trim this up because I need a line. So if I have to show you the difference, so if I just click here, veteran, the line is gone completely.

Okay, but that's not what I need right now. So I need only this particular part of it to go. So either I can draw a line like this on the horizontal axis and then I can animate Okay, turn this below par, or else we can just complete the curve as it is given. Okay? And then we can go ahead and trim it. So I'm just going to select line.

Just click anywhere on the surface and if you're not able to pick so if you see this particular thing highlighted in blue, and red So, if you see here on the top you have all these selection filters, okay. So it has the endpoint, midpoint control point and there is something called as point on. Okay. So this point on if it is switched off, you will not be able to select anything if you see the red and blue is some is just highlighted here, it does not highlight it here, okay, in case you have a problem, just make sure the point on curve is checked on, okay? So you'll be able to drag it. Okay.

So now I'm just going to click here. Okay. I'm just going to click here and do you see the symbol now the symbol, which you see now is called a tangency symbol. So it's ultimately taking a geometric constraint, okay. And if it does not take it also we can add it later. No problem.

Okay. So from here, I'm just going to select keep it vertical, okay. It escaped. And we're going to do the same thing, even here. So just select the line and chocolate for line. LS Chima.

Okay. And now what I need to do is I need to ensure this, these both these both lines are tangent to each other, okay, let's see. And any to click on the tangency symbol, Okay, this one with this one. And we'll take constraint only exists because when we had actually placed that particular line, right, so it had already given us that option. So of the tangency sum, right? So that's what is contained on the axis.

So what I'm going to do is I'm just going to right click, select formulas just for you understand, okay tangency and I'm going to delete it. And I will do the same thing on the side, select tangent constraint, and I'm going to delete all right, so now tangency is deleted, and if you see I'll be able to drag it. Like whichever direction I want, I'll be able to drive it okay. See this. Alright, so what I'm going to do is geometrically constrain it first tangent constraint. So I'm just going to click on this line, select up, click on this line, select.

Okay, so now we've added the tangency again, okay? And now what I need to do is just needs to constrain as basically because length is not constrained, so that does not matter to us. Okay? So what I'm going to do is I'm just going to trim out the lines, okay. So how do I need to trim this? I need to trim this and this is this and this.

Okay? So this is it is a sketch needs three constraints. Okay. We'll figure that out. And for trimming options, like I said, are the easy ways to just drag it. Okay, so I'm just going to do Ctrl there.

Alright. I'm just going to drag it for you. So I'm just gonna hit trim T and what I'm doing Dewar's I'm just gonna do this. Alright, so you see the curves achieved. And now we need to see which one needs to constrain, okay, we already given the diameter for this, right? And if you see this particular length is not constrained.

So if you notice this, I'll be you see this. This particular length is not constrained. So now I'm going to hit the geometry constraint, and I'm just going to hit the equal length. Okay, so I'm going to try and make everything equal here. So this is a collinear symbol, okay, so don't get confused. This is an equal symbol.

So this one with this one, okay? I made it equal. So I'm not constrained to meaning these two equal Let's try to check which constraint is missing here. So I believe dimensionally everything is constrained here, right? The base profile is constrained and on fit. So let's check here.

So this profile is constrained to the coupon from 10.5. It's all done. Okay? And what I'm going to do right now is just, I'm just going to try to track the points again, to check with the constraint. If you see, I'm able to move it up right. So basically this length, like I said, before, this length is not constraint.

Okay? So those equal length, it just needs the value. Okay, so the value got deleted when I trim the line. So we had given this value before if you remember the 20, so that got deleted so I'm just added dimension this control can use vertical or infer anything to do just that. Like to point and select to be secure and the value would be 20. And what now we need is one more constraint and the best way to find it, like I said is always to drag.

And there's another way as well okay? So just hit C or D other dimensional constraint origin metric constraint, okay. So when you do that, you would notice that everything which is constraint is in green color, okay? This is nothing but ISO constraint, okay. And this one, this red line, that is right, it means it's under constraint, it will actually show you like, which line needs constraint, even if you open a dimension constraint with D, it will still show you that particular direction, okay, so equals. Now let's find out which side needs to be constraint.

Okay. So if you notice this midpoint constraint has gotten deleted, somehow so let's So that that is a reason which is moving, okay. So this can be constrained by using the midpoint constraint, okay? So make sure you select a line, okay and select a vertex. So now it's fully constrained. Alright, so here we have a sketch and this is a big no sketch.

Okay, so in the next session, I will discuss a little more intermediate sketch, okay, and post that we'll get into the modeling, right, and the other options of the sketch will be discussed along with it. Thank you.
