Hello friends, this is Rahul, come to my session model dimension in sketch. So let's start with creating a working directory. Click on File sessions select one select the working directory. Click ok. To start the new state, click on new use case some name and then click OK so now we are in sketcher In the previous sessions, we learned about sketching ility and constraints and today we will learn about dimensions. I'll draw a simple rectangle select and delete the start point and select the double click middle mouse button. Here you can see there are two dimensions and these dimensions are called v dimensions.

So they are given by creo automatically three types of dimension first is MC dimension, then strong dimension and then loc dimension okay. The dimensions which are given by creo automatically Those are v dimensions. So we should not keep three dimensions in our drawing. We should always make them strong or locked dimension okay? To make them strong dimensions you can edit them them we should edit them okay to add double click on the dimension double click for example 16 and this so, this is a strong dimension and this is a V dimension. What is the difference between strong dimension and with dimension, okay, big dimension can be automatically changed by crew but not this Strong dimensions.

Okay, let's see how it works for example, so these are v dimensions. Now a given tangent constraint first let's see what is the dimension Well, it is 6.97 Okay. Now add your tangent constraint line and select circle. You can see this 6.97 dimension became 7.23 so it is automatically changed. So they are not defined by us. Okay.

It is given back to you So, let's do the same Again with respect to dimension 60, okay, verify it does not change. So, now I delete the circle and delete a drawn circle in this case here now we do the same thing, do tangent constraint, and let's see the dimension 60 will change or not click tangent line See, the dimension 16 is not changed. Instead, the diameter of the circle had change because the diameter of the circle was with dementia and not this condemnation. So, what we have learned, we should not keep the weak dimension in our drawing. You should be converted into a strong dimension Okay, all these weak dimension as a strong dimension, how to do it by double click on the dimension on 7123 I do know I do the dimension as a one, then enter. So this is my strong dimension, you can identify them by their colors, the blue one, this is your skewed the dimension to the circle as well as the diameter to eight mm, double click on the diameter and then put it into let's do the distance 2.6 s as a stronger dimension.

Let's make it three. So, How to do it double click on it and then put the dimension value for example three and then enter this dimension or no strong dimension, okay dimension strong dimension and the third one is love dimension. Okay to understand that let's do another sketch. First I will delete everything. So I start with the center lines I draw vertical and horizontal center line. So this way I did the start point of my sketch so vertical and what Under.

So this is the sort of escape. Now I draw rectangle, select rectangle, click the start point. Select in point, double click middle mouse button. Okay, now let's make this dimension. These are weak dimension strong. So let's make this 14 dimension too strong.

Let's change to save one, double click on it. Save one and enter. Let's define the location of this rectangle. Let's define this 4.33 mm dimension File, double click on it and then press enter. Let's define the height. Change 2.56 to double click on it.

So now I have my rectangle. Okay, now let's learn about the log dimension. Before the strong dimension does not change automatically by crew goes, we don't define them, but they can be changed. If we drag them, drag them is. For example, I'll select the age of this rectangle And then my strong dimension changes. Let's do this.

I select this line and I drag it. So keep raising the leftmost button. See, these these are these changing but I don't want it should be changed, then I make them locked. Okay, let's define this 14.97 to 15. How to do that double click on it? No, I should lock it so that it should not change.

So Do that, select the dimension right click, select lock. See, this could have changed. And the lock damage sorry, the stronger dimension is blue. The love dimension is brown. Now let's try the same thing as I as we did before. Select the edge of the tendon and drag it keep pressing left mouse key button and credit is it changing?

No, it is not change, but a change. This strong dimension has been changed. So let's lock this as well. Let's make this 13.37 as the name double click on it Now let's look at select the dimension right click, select No, no, no live students will select the line. Now what is moving, my center line is moving, but my dimension is not changing. same routine is same.

Let's drag it vertically. Flip the horizontal edge and move my strong dimensions Let's log them as we select this 3.81 double click on it, make it for that click unlock. Here's define the height of a triangle. Double click on the height seven, press enter. Select right click this way my rectangle is properly defined. Now I select contract.

Snort or sorry snort chindi what is changing the center lines I hope you understood the three types of guys munition first is weak which is owned by creo Okay, the second is strong which we define it, but it can be changed okay and the third is locked there it is until we edited it will not change. So always try to keep always the log division. Okay. So first delete everything except the centerline. Click the area and click on delete this is the repeat No, add a circle circle Come on Select the center of the circle and define the radius. Double click OK. Let's define the location of this dimension.

So the horizontal location, the dimension is 10.63. Let's define it to 10. Double click on it, then enter. Let's make it fail. Let's make it for example. So double click on the week dimension 9.41 Before you know it is defined okay and know how to lock it or do at once, select all these dimensions and lock it.

So let's delete all this dimension ctrl key right click. Now it is locked which are given by itself. Okay, now let's learn to do the dimension by your own Yes dude this dimension first is consulting Okay, let's do the dimension by you do that, select the dimension command or the normal command select the surface enter and then click middle mouse button. This is the dimension given by me. You can edit this value. For example, I edited to 11 this is the dimension Okay.

Now let's do the dimension, the vertical position of the circle. Let's define to the forum. Okay. Select the normal for the damage Come on, sit in the center of the circle. Select the horizontal axis in the Kabuki or without control in the previous versions of you, it was essential to use the Ctrl key but now it is okay. Let's define this dimension for him.

Double click on it. Now we have defined the horizontal and vertical dimension. Now let's define the diameter of the circle. Let's define the diameter of the circle okay. Select the cell select the division command select the circle and then click middle mouse button. This diameter of the circle or radius This is the radius of the circle.

Diameter of the circle. So how to do the diameter of this? again no biggie how it came I will tell you delete this Lu, listed in 2002, view the radius of the circle. Click only once on that circle. To view the diameter of the circle, click twice. Okay, let's do that.

Live the dimension command. I click once only. And then click outside middle mouse button. This is the radius of the circle. Okay, now I want the diameter of the circle. First I delete this delete and now I do the diameter of the circle by doing double click on the circle.

Now I click two times one, two, and then click outside middle mouse button. Here it is. diameter of the circle select liquids liquids the most voice memos understood it stayed at circle. Sorry, I'm in the dimension command you can see here. This is active. Okay, so it means I'm still in the dimension command to come out of the dimension command.

To do price middle mouse button click twice with a mouse button. Okay, now I select some circles. And then we do the circles. Here's the radius, diameter, radius diameter is two. Select the image and click once circle button, I would say, is this enter key. No, here I do diameter.

I select two times the circle. middle mouse button outside Mm hmm. Now what it is asking me It says there is a conflict, why there is a conflict because of the constraint. You can see here r1 and r1 in the previous sessions we learned about constraint, okay. Now these are equal I'm trying to do another value create, so, it is giving me the error okay. So I can resolve this or I can do anything like for example, I delete this constraint value in the list of these three, I select the last one constraint equal it is it is a delete command.

I can delete it. So, now, it okay could the value for it for example, seven Same with the dimensions. These remaining circles here five, six and seven liquids double click the circle because diameter for the audience I do the same thing deleted. We can do well Have you understood this? So, that's all for today's session guys. We will continue with the dimensions in the next session.

Till then keep practicing. Thank you and have a nice day.
