Hello, today we are going to discuss about two dimensional sketching. So for I have the next open already, so I'm going to click on new. I'm just going to select the model here and just have the directory set as well. And let me just name it as two dimensional sketching. Okay. And now we have the coordinate system here.

So I'm just going to select the sketch. I'm just going to select a plane here. And then I'm going to click on OK. And if you see here, you will have a lot of curves here. So this is what we're going to discuss today. So majorly are the point circle, the arc, the line, rectangle and the profile. Okay, so we'll go one by one and oh, Also, alongside I'll also show you how to constrain this.

Okay, so let's get started. So before we get started, you see, we'll see what are the things that are being checked here. So when you click on More here, right, so you would find all of these things. So it's basically the continuous auto dimensioning. So what is this continuous order dimensioning. It's currently checked on because you see it highlighted here.

So I'm going to click on point here, Let me place it anywhere in space. So if you see here, there are two dimensions, which is taking automatically. And in case I am going to switch over to continuous auto dimensioning, I'm just going to select a point. And we're going to place it in space. And you see there is no dimensioning here. Meaning that that's like needs to constraints.

Okay, it's not being constrained. So what I'm going to do right now is, I'm going to show all of these dimensions to you with continuous auto dimensioning so that you have a better understanding about it, and Okay, so I'm just going to keep it on. So, this particular points like the waste how to constrain this again. So, first of all, let me just delete this points there are different ways of placing this points. So, this is basically a filter which I selected. So this is basically just for selection purpose and UCCS wires go feature datums feature point, sketch, sketch constraint and view.

So this is to just make your selection procedure more easier. Okay. So, I will find this, the users of this mode as we advance for the sessions. Okay, so let me just select a point, what are the different ways of placing a point you can just place it in random space, then you can do dimension or I just click on this plus button to the point dialog, okay, and just select input point it's okay. And I'll give the x direction which is basically This direction, okay. So, let me just give it us 20 and the y direction will be along the positive y axis and that will be 20 in case you give negative one then it will be negative, okay.

So you can, you can change the direction if you want to. So minus 20. So the point would come down, and then this dead, it does not really matter in the 2d plane, because when in a 2d plane, the sketch point only has like two constraints would be more than enough, just two directions need to be arrested. Okay. So we'll just click on OK. So, if you see here, I have placed point and there are two dimensions is fully constrained with two or two dimensions.

So I have placed the point here by pressing on this point dialog, but however, it's still asking me to constrain this. So what I can do is so I just right click on this particular thing and Okay, looks like the filter is on here. So I'm just going to put on no selection filter. I'm just going to right click on this and there's an option called us convert to driving around. So just click on convert to driving, right click Convert to driving. Or you can just even right click Convert to reference, which which basically means the auto dimension or convert to reference.

Okay, so, the other ways of doing this, you can just right click and press and hold the right mouse button. So you will find couple of options here. When you just crawl moolah, you get the Delete option which deletes it. Let me do control that. Okay, and the reason that it's showing in brackets is because any reference dimension in CAD will be represented in these brackets. Okay.

So, the other options that I have is settings, which I'll discuss a little later and hide. So, you can just hide this dimension this press and hold hide this displace and hold hide this. Okay. So now this point, what are the different ways of constraining this? So let me just place it here. And let me first try to dimensionally constrain it.

So what is the shortcut for dimension constraint? So you can either go to happen dimension, which or just press D on your keyboard. So here you have the rapid dimension and the rapid dimension. If you see, there are different ways of constraining this. So, we get into each of those like one by one. So, the rapid dimension for this, so I'm just going to select this.

I'm just going to select here randomly, and you will see that I'll be able to see, do you see this I'll be able to drive along because it's the point right? I've selected the origin point and This point, so it's taking along a different direction. So I can drag it this way, or whichever side I'd rather it. So it just, I just press, it's just gonna take the dimension. Alright, so, how to make it easier. So let me say, I'm just going to delete this dimension, press and hold, drag and delete.

Okay, I'm just going to switch it off. Okay, and D again. So let me say I want Vertical, Vertical dimension, okay, so I'm just going to click on this particular thing, and pointer have a cure. So I'm just going to drag it and place it here, okay. And if I need a horizontal one, I will just select this particular axis or the origin point, and I will just select the point and drag it up. So here's my dimension, horizontal dimension.

And if you see it's fully constrained, but to order dimension Because there's another point, yes, there's one or one point here, and it's not a point here. So what I'm going to do is, let me try to, there are different ways of constraining this, the first one I can do is I can just select this. Again, I'm going to drop in a horizontal dimension. And I'm just going to select the vertical one as well. Okay, so now it will be fully constrained. Right?

So in case I want to a geometrical constraint a point, so I'm just gonna click on point, I just place it here in space. Let me select, let me click on C. So I'll go here and select geometric constraints or just hit C on the keyboard. So you will have the geometric constraints come up. So here you will see a different constraints here. So first, let me show you one by one. So what I'm going to do right now is that I'm going to try to constrain it geometrically.

So, this point let me make it are the data the origin here, so just press on See, you see this first one coincident so I'm just going to take this point and so make sure this automatic selection progression is checked on so it moves to the next and then I select the sketch origin, okay. So in case there are multiple points, so that's when you get this quick pick options very useful tool, last use sketch origin or the origin of the datum coordinate system. So, I did it you can select anything in this case, okay. So, if you see here, the point is here. So now this this constraint, this point, if you see the sketch is fully constrained because this origin is already at 00. So when we place a point at the origin, it just gets automatically constrained.

Okay? So let me just do control it. Okay, so, I have the point here. So let's Try to use a different geometrical constraint to constrain it. So I'm just going to press on C. And I'm going to use point on point on curve is nothing but this point against any curve. It can either be this axis, as well as sketch horizontal axis, this can also be cultures occur, or, if not, we can just click on line here.

I'm just going to place a random line. And let me use C. So point on curve, I just select this first point here. And firstly I'll select sketch horizontal axis. And you see this particular line here, the dotted line that indicates the relativity or the point on co constraint, okay, so I'm just going to select Ctrl Z, and just going to hit c again. So I'm just going to select this point with this curve. And you will see that this point is this curve is moving With respect to the point, right?

And if I, if I had not constrained this, let's say, I do control that here, okay? So what I'm going to do is I'm just going to dimension this particular line, let's say this. So click on geometrical to select this point. And when you use point on curve here, did you see this move, okay? And then I'm going to use this point. I want this point here along along this particular curve.

Okay, so now the vertical is constraint, the horizontal is constraint the line. So what I'm going to do is I'm just going to select this point and just select this line. So if you see here, it's come down, because whichever entity is like free in space, that entity will particularly move because we only locked this in two directions, so it's moving this point. All right, and Okay, now I'm just going to delete all of these points. Okay? Select point.

Okay, I'm just going to hit the delete button, or just press and hold the right button, right mouse button and just drag to delete, it will get deleted. And selection filter. I'm just going to delete this as well. Okay, and now, I'm going to show you support we discussed the basics of points. Now let me just show you line. So how many dimensions are required for a line?

So let me just show to you. I'm just going to place this line here. So before we place, so I just first click anywhere on space, and then I can type type in the length here. Okay, and then the angle, if I needed need to line at a particular angle, I will type in the angle here, or if not just leave it at zero. And, and here we have the placement of the line. Okay.

And it's automatically taken this as a driving dimension, because I'd already mentioned the value there. But in case I had not mentioned the value, then I would just go ahead and place it here. And I just place it here. So it would show me like, two continuous dimensions. Okay, risotto dimension. So how do you constrain a line?

So how many dimensions Do we need here, so we got the length. And so if you see, I'll be able to move this horizontally and vertically. And the same goes with this as well. But the difference is, so I'll just be the cyclic on this particular point. I drag it up, you see that it's moving Vertical itself alright. So, now we have these particular dimensions here and what else do we need to constrain this?

So, let me just click on press T which is rapid dimension alright. So, this particular point and this particular point with respect to the origin is what we need to constrain. So, we can do that either using a dimensional constraint or a geometric constraint can use the perpendicularity horizontal vertical. So, since I already showed you the horizontal vertical, let me just show you the perpendicularity this one with respect to the sketch horizontal axis. So, now I'm going to place this particular dimension here and the same goes But, so, now, what what else do we need to constrain? So, we have constrained the vertical aspect and now we need to constrain the horizontal aspect if you see here, this particular dimension, right, this is what we need to constrain.

So, I'm just going to click on dimension To the end, and perpendicularity and just going to select the sketch vertical axis. And I'm going to select this particular dimension dimension and I'm going to place it here to be we have dimensionally constrained this particular line. So let me try to geometrically constrain this particular line in here. So I can do it with respect to the origin or with respect to this line. Anything. Okay?

So firstly, let me just press on C. So you see the like, lot of other options that you see here. First of all, let me just give it a point on call constraint. Okay, so I'm just going to select this point is going to have I wanted to start exactly at this particular point or so. You co so both of it came on the same line. All right, but so I'm going to do just do controls it. And I'm just going to hit geometric constraint again.

So I'm just going to select this particular point and when use this so you see here the difference. So it's almost same I mean like just lying on the same line, that is what the point on co means, right? So it says with two or two dimensions, which basically means the start position is constraint. So I need to constrain the length and the vertical direction. Okay, so just going to select. I'm just going to select geometric constraints.

Click on equal theists. So this almost looks similar or parallel. symbol has a slight angle in it, when the equality symbol, it's horizontal, basically a symbol, okay? Just click on this equal length, and I just need an equal length of this. So just select these two, if you notice, so these both are like equal, since I've given this as hundred odd bits also be hungry, they want to cross verify that I'm just going to click on D, which is going to select info horizontal, anything that's fine. So I'm just going to click and drag.

Okay. So if you see here, this particular dimension is shown in red color, it basically means it's over constraint, okay? And this kind of geometry or dimensions is not acceptable. So we need to always ensure it's fully constraint, okay. And so what I'm going to do is I'm just going to delete this, okay. So what are the one dimension that is missing?

If you see here since continuous or dimensioning is all we know that it's a vertical direction, but in case this is not there, then like I mentioned before, the easiest way to find out would be to try to move the point in different directions and see which direction is moving and we would be able to know which one to constrain. Okay, so I can either right click and convert to driving or I can just press and hold the right mouse button and convert to driving. Or I would just press on D, and I would dimension this. Okay. So I'm just going to select this. Just going to select this two points.

Just going to select these two points and I'm just going to place it here and now it's fully constrained. Alright, so we have like two lines. So I've shown you how to geometrically constrain it and how to dimensionally constrain, okay. So let me just delete all of these curves. Okay. Just select everything hit the delete button.

And so now we see in point and align economics is going to take a circle. And what are the dimensions that is required for a circle. So there are three dimensions basically, one is the diameter or the radius. And next thing would be the distance from the horizontal and the respect to the vertical. Okay, so I'm just going to place the circle here in space, and just close this. So if you see this, like I said, so the first one would be, I'll be able just press and hold on the center, center, so we'll be able to move this vertically, horizontally and in different directions.

Two dimensions are enough to arrestor. And what is the third constraint that we have? So it's basically the diameter, okay? So what I'm going to do is I'm going to constrain this dimensionally first. All right, so hit the D button. And it's pretty simple as Like how we discussed for the point and the curve, so this is a point we need to constrain.

So I'm just going to place it here, right and then the same thing. I'm going to do this, I'm going to select the sketch origin, select the circle, drag it up. So we see like, two different dimensions. So it's constrained with one auto dimension and one that one auto dimension is basically the diameter, and I can just right click and click on convert to driving, or I would just select D, and invert, I can just click on this arc here and just drag it out. So that would give me the diameter or we specifically want diameter then go ahead and select to diametrical type, okay, and then let me just delete this first, because it will get over constraint. Okay, so d diametrical, and just select this alright, So which was convenient for you?

So this is how we're going to constrain with respect to dimensions and how to be constrained with respect to the geometry. So, select geometrical constraints or let me create another circle here, okay? And it see the geometric constraint, we have different ones coincident point on curve and all of that right? So what I'm going to do is, since is already constrained, I'm going to constrain get the same dimension here as the circular. Okay, so firstly, what I'm going to do is use something called an equal radius. I'm going to use that.

So select the first one and the second one here. So that is that we've got it. Okay. I want this particular point to occur here. Okay, so I'm just gonna select point one, make sure this is checked down, select this point and select the horizontal axis and I've got this circle here. And what is If I want this particular dimension, if I want this particular circle to lie here, I will select c again, like coincident.

And you might have an old constraint geometry. So let's check that. So just select here, and I'm going to select the second sketch origin. Awesome. So it is fully constraint, okay. And basically this, another constraint wouldn't be required.

Okay, so we have the coincident and the point constraint, since it's at the origin, just one is more than enough. So I'll remove the point on constraint, okay, just select and delete. Okay, let's get is still fully constrained. And this how we constrain a circle, okay. I'm going to select the curve, this, select the close here, just hit the delete button. Okay.

And so in circle, we also see circled by three points, all right. So that is basically the gist. Show like two points on the curve. And you just drag it out you can just get the diametrical value and you just place it okay. So this is the use of this I'll just show you when we get into the sketches okay and the parameter mode. So parameter mode is nothing but you place up the diameter first itself.

So, let me just see the value the diameter diameter was placed. And I just click here, okay, I can just place it so that and let me just let me just select this. Let me just delete this. And how do we do a parametric mode for the line you see parameter, okay, just you can get the length and the angle, you will be able to take the line to learn. And let's say I want to get angle 45 degree. So you just drag it and place it wherever you need it.

Just Read this No. Okay, and let's discuss about a tangle. So in rectangle we have like three types of rectangle one is from by two points by three points and from the center, okay? So two points is displays the first click on the first point and the end wherever you click the end or from the second point, okay? And the next one is by three points. Okay, so I'm just going to zoom out a little by three points.

So just press the first point. And it's asking me where do you want the second point? Okay, so I'll just press it here, or I can press it here, okay, anything. So if I'm going to press it here, I'm just going to drag it down. And I'm going to press it here I'm just going to grab it was the same okay. So this is with respect to the second one by three point and third one is from the center and basically similar to a circle.

It will take the rectangle from The center. So can either do this, or just drag it this way too. And you can keep the values here itself, okay? If you want, if not, or you can also place the dimensions a little later. Okay? So just going to select all of this code and I'm going to delete this.

So I'm just going to show a constraining of just one rectangle for now. Okay, so let me just place this particular thing here. me so how many constraints as a rectangle need support? How many sides does a rectangle have? It has like four sides, okay? So all the full lengths need to be defined.

Alright. And next thing would be to basically, since it's like four dimensions, this would be parallel to this. By default, this would be same Okay, so for a rectangle, one side, the dimension will be equal to the other side. Alright, so the shorter edge would be equal to the side and the longer edge to be equal to, it's no longer. Okay? And what I'm going to do right now is that I'm going to try to constrain this.

So I can, so what I'm gonna do is I'm just going to right click go to driving, I'm just going to convert to driving, or in case you want to change the value of something, what you do is just double click on this. Okay, when you double click, you would have the value here, change it here, or you can change it here. Okay, so let's see, I want it to be 700. And this validate state and what I want to do is I just wanted like dimensionally constrain it for now. So what I'm going to do if I need to geometrically constrain Alright, so I'll show you the different kind of geometric constraints that can be applied on this. Firstly, select the sketch dimensions.

Hit delete, okay? And so I'm going to use geometric constraints and I'll use the midpoint constrain. So what I'm going to use this particular line, I want it exactly at this, this midpoint, okay, I'm just going to place this and select the sketch origin. And if you see that attract mood, Okay, the next one I'm going to do is I will do a midpoint constraint even for this, so I want this one at this point. Okay, and now, I just need to give the vertical distance and horizontal distance. Okay.

If you see this, and I just need to give this dimension for just 600 Good. Let's double click and so here's a rectangle which is fully constrained again and you can use similar principles which we discussed with a point in line that is for the coincident or point on or equal and again, you can just you can use those options as well. And next one which we have is the arc, okay, so you have like arbitrary points are present the point so i'll just show up by and just delete this close. that center point I can use the center any sent any random center from you is click center. I can just give the angle here. Just press and it shows you the Aqua center point, okay?

And how do we constrain this or what are the different dimensions we need? This point is, is mobile, right? And this point is mobile, and we need a radius here. So I'm just going to press on ch metric constraint, select point on, select this particular point, and I'm going to keep it on this vertical axis. Select this particular point, I'm going to keep it on this horizontal axis. So basically the same to study degree which I mentioned earlier at achieve thought, and now I have this particular radius, I can just double click and I'll just change this value.

This probably give like 150 or something, okay. So your Heaven's Gate, which is fully constrained, and then Same goes with my arc by three points. Okay, so I'm just going to select one arc. Okay? and proceed to equal radius, right. So what I'm going to do is I'm just going to be equal to this to both.

Okay? And I'm going to make it point one. And we'll make this point also point on. And the only dimension that we have left now is of two dimensions. One is for this point because it's just moving, right? So we need to constrain that.

And then we need to fix the distance for this. So I'm just going to use a dimension constraint for that. Always give with respect to the Art Center never give with respect to the point that's not a good business. And practice. So this particular dimension as to movie, and what I'm going to do is I'm just going to hit dimensional constraint. And I'm going to make this now it's fully constrained.

So the same goes with circle by three points as well. Okay? So just the creation method, but our the constraint procedure would remain the same. And the same goes with the line or the point or the rectangle. Okay? So I'm just going to delete this curves now.

Now talk about the profile. So now I'm going to just switch off this continuous auto dimensioning and just show you this profile. So you start off from here, okay. So if you see the difference between a profile and liners, the string breaks this continuation, which is there, so I can just like click, I can just click and go. So this particular thing is not there in a line. So if I go ahead and select a line, I just go ahead and place this there multiple lines which I can place if I'm going to place this particular line here.

So I can select from the particular point and I can take it take it forward, okay. But however, there is no continuty. So let me just delete this close. And let me just select this profile we'll place it here and the benefit of having a profilers, you can draw a curve, this arc, and this line combined together is the profile. Okay? So let's say I want a profile like this, okay?

So I'm just going to drag it up like this, and I just select the endpoint, I have arc. So I'm just going to do the same thing I want an arc down downwards okay. So I just drag it down, I just clip the second point. So as when you use it, you will get the hang of it okay. So and sometimes what happens is that if you not be able to move or to just move your mouse a little more up and you would be able to get it okay. So, this is the use of a profile and it is needs 14 constraints.

So similar to constraining Point and align, we can constrain this particular thing. Okay. Thank you
