Welcome to today's session. Today we will continue with this module. In the last session we learned about dimensioning. So we'll continue with the dimensioning tool again today. So let's start. As usual, let's start with creating the working directory.

For that select on file and select delete the folder. Click ok. To start the new skater select on new select skate. Do the name plus skate. Then click OK. So now you are in a skater in the last session Start with the damage. So let's create the new sketch.

Start with the center lines define the center. So I create the center lines vertical and horizontal, underline vertical. The line double click middle mouse button. Okay, so to my center is defined. So let's start with giving dimension to the triangle. We learned about circle in the last session how to do damage to the circle, about the radius and diameter.

Okay, let's start with rectangle. So in the last session we learned about editing the dimension. But now we learn how to good remix By own Okay, so first let's define the horizontal or horizontal location of this triangle. So you have to select the centerline vertical centerline and vertical line of this rectangle, vertical view, the horizontal location. Do that live division Come on, click vertical center line. Select the vertical line or vertical edge.

Click middle mouse button. Okay, dimension let's keep it parliament. Let's define the vertical position. Okay, let's define it as a file again. So we will select the horizontal center line and the horizontal edge of this rectangle. Let's start dimension interlay with the most burden let's define the length of this triangle.

Let's define this as a dynamic. Okay. We can define this by selecting these two vertical edges and then middle mouse button between them when you start Okay, define these 10. Let's define the height. To define the height. We select the horizontal edges of this angle, and then we'll flip the dimension command to horizontal edges.

Middle mouse button. Let's define for us. Okay, can define the length of the rectangle are defined by selecting the two vertical edges, but I can define by selecting the line. Okay. So let's do that this to define the horizontal dimension of the main just select the line or the and then the dimension line with the mouse button in the vertical line in the middle okay. This means when you So let's try for the line.

So delete this rectangle and create a line. Define the dimension. You can do it by selecting the two endpoints. Or you can just define by selecting a line through this time both ways. Click the dimension command the endpoints and demos button. Let's try with another way by selecting the line dimension you can define it to do the dimension to the entity, okay.

Now let's learn the next type of dimension that is the reference dimension okay. The reference dimension what is reference dimension definitely dimension is this dimension which is not your requirement or this is not what you want to define, but this is the extra dimension. So, the reference dimension is an extra dimension you add in your drawing, okay. So, just for the reference, so, that is not what you want to define it or that that dimension is not with tolerances. For example, But only for references. Okay, let's have some example for this.

Okay? Define the centerline input. Okay, let's dimension this rectangle 10 by Google the position of this rectangle So, all the dimensions are defined or I can say, my table is fully constrained. It means I don't need any external dimension to define this rectangle. So my position of this rectangle is defined. horizontal position, by dimension.

Vertical position by, by length and height is also defined. Greatest. But, for example, let's see the supplier or the manufacturer. The additional dimension for example, from this vertical age, to the center line in its experiments, emission, this is a simple case you might not understand it. Why he needs so, because it is by calculation it is clearly defined as 10 plus two is 12 it should be, but in complicated cases you will find some examples or some cases where it is required. So, in that case, you have to define the reference.

Okay. So let's select the reference dimension and define the dimension between this particular age and center with the most burden, so this is a reference. So, you might have thought that I could add you on the normal dimension, but you will not take it if the entity is already defined fully cured does not accept the additional dimension. So let's try believe this referral dimension and do the same dimension with the normal common normal Why? Because my rectangle is fully constrained rectangle is fully constrained that's why I cannot give additional dimension. Yeah, I got an optional undue dimension difference from here as well I can make it as a reference.

If I select dimension reference, it will be reference reference. So, you should do a reference dimension or delete some external dimension to add that will value for example, for your design purpose you needed 12 and If you don't need this to mm, let's say for example, you do not need this tool and you need for your design, then you have to delete this too and add it to a dimension. Okay as a normal dimension, so let's try that. Here I'm not getting to dimension to delete. So, first I delete the dimension and then I do that well cancel this. I first did this.

No. So the accepted dimension right okay. Understood. Right. You do not want to accept the extra dimension into your drawing practices as well. Define fully define the future without any external influence, it should not create confusion to the manufacturer should not create an future present to the supplier or the manufacturer.

Okay hope you understood this about the next type of dimension that is a baseline dimension. So, baseline dimension is a type of dimension where there is only one reference and from that reference you define all other dimensions. Okay, it is very helpful to the manufacturer. So, let's do that. So let's start with creating example. A good example for this Know how to define the baseline dimension of this all these ages ranges from these standard lines.

So, my starting point of all these dimensions will be the center line. From here, I define these, these, these define the baseline to define the baseline we use baseline dimension And then select the axes and then middle mouse key and it asks for the vertical version, they see this line the center line with the most key. So, you can see here this vertical line became my baseline 0.00 so this is a start point. For next time, I have to use a normal command and use this baseline dimension to give the dimension to all other lines. Okay, so I use barman command, then isolate the baseline select the line to dimension and go to the menu. In this meeting, you can create a baseline dimension.

Let's do it for all other lines. Lift the dimension, lift the baseline and select the Dimension Line. There is one thing to select the bass line you might go problem flipping the line facilitating this bass line. You see, the center line is not his bass line. So there is one trick you can use. Take your mouse on this dimension and then click the right mouse key button.

The baseline is highlighted. Click the left mouse key button. Yes, notice selected and then select the line to dimension. Create the baseline dimension suite for the last selected isolate. Right, once Yes it is. Click the leftmost button.

Yes and then you're the most For the vertical baseline dimension, I created another example. similar example let's assume this horizontal center line as my baseline, and how to do the damage to these horizontal lines. Okay, so firstly is to set the baseline. Okay to save the baseline, delete the baseline command select the horizontal line, bigger most key button baseline is selected. Okay. Now with the normal dimensions select the base line okay the bass line the line so what we click right mouse button and then click left mouse key button the selected line and middle mouse button left mouse key button left aligned Oh, we got an error.

Why? Because there is an element constraint. We have to delete that one constraint, or it isn't making us to make this dimension delete, or difference. So I prefer to delete the Elven constraint. So let's delete it. Okay, Dimension Line.

This way you can view the horizontal and vertical baselines. Let's try with another example. This is 90 degree because this vertical and horizontal lines does not have the constraint. Learn how to define the vertical constraint, select the vertical centerline Okay, there's no problem with the vertical horizontal constraint Okay, now we know how to define the dimension of this rectangle by baseline and I take this point Okay, let's define the baseline the baseline constraint explained Come on, we don't know and it asked me vertical or horizontal, why because in the previous examples, we calculated vertical center line and what is in the center line, so, for creo it was clear how the dimension to be defined okay. But, but in this case, we have selected the point so, it is not clear, you want the vertical or the horizontal So, we have to select For example, I have to define the length okay.

There are different then to define, this is this line as a vertical because vertical and then Define the length in the horizontal dimension. I choose to vertical, a sip and this line is vertical. We do the most key button, click dimension baseline vertical line with the most key button. So I'll define the length of this rectangle by baseline dimensioning ordinate dimension. Now, let's define the height. Okay.

In that case, we have to create the horizontal baseline. from origin to baseline. We have to define the height. Okay, let's create the baseline baseline the point demos presented the basement horizontal and vertical baseline to create the ordinate dimensions, we call them as ordinate dimensions. Okay, so we learned about how to do normal dimensioning reference dimensioning and ordinate dimensioning. Okay, let's learn the last type of dimension that is the Demeter dimension.

Okay. dimensioning draw it dangle Define the height and width have defined height and weight. It can be 40 Okay, but sometimes define a feature with the perimeter, okay. And then I can use a perimeter dimensioning tool if I want to define rectangle with perimeter for t Okay, then I can use pavement to damage me okay Find the perimeter of this rectangle. Select the dimension and now select the rectangle okay. Click one by one all the edges use ctrl key okay.

Click the middle mouse Now select the dimension you want to be variable okay. So, you have to keep one dimension variable to define the extra dimension that is the perimeter right because I already explained before as well he does not accept the extra dimension. So, in this case, we have to define the perimeter dimension. That's why we have to make one other dimension as a variable dimension Okay. Now, for example, I have to define this horizontal plane as a variable. So I select the row Horizontal perimeter of this rectangle could be the name variable.

So variable dimension I cannot. So if I want to edit, I can edit the perimeter, things change all types of dimensioning so that's all for today's session. In the next session, we will learn another examples or another commands from the Scripture. Thank you and have a nice day.
