Hello friends welcome to my session. Today we'll create our third exercise in skater creating the working directory. Click on File Manager. Click Click Click ok. To start the new structure click on new in skater For today, let's understand how to start this for me, is like a start from the center, making this a center line. switching colors looks like symmetric all over. So this can be my central point, and then I can start my sketch.

So let's start that way. Or you can choose any corner as your starting point, and you can start you can start. So for me, I'll start with creating the center lines, vertical and horizontal. And then create a rectangle like this and inside that then I start creating these sketches and then it will be easier. Okay, so let's start with this. So let's start with creating the axes or center lines, vertical and horizontal.

Click on center line, click on start point and then input vertical column shows your vertical constraint here, you can choose a vertical centerline and a creator, horizontal center line. Doubleclick middle mouse button. This is your horizontal line and this is your vertical centerline. So I have 114 we should be symmetric all or So let's start with rectangle command, click on the rectangle, pick your starting point. Drag, drag until it asks you for the symmetry constraint. Look, here it is submitted customs creo is automatically asking you for symmetry constraints.

You can click that because any way we want it. So not horizontally symmetric. Please make it symmetric. So let's practice make them symmetric using a symmetric constraint. So for that Delete the existing symmetrical scale first consider the constraints selected both the symmetry constraints and right click delete or use the delete button on your keyboard drag them see, no this is unsymmetric this length is different and this length is different. Okay this length is different and this length is different.

Now I will make use of symbols So, first select the symmetric select the first endpoint of the line that you have to make a symmetric select another endpoint they select The centerline here you can see it is symmetric then look slightly symmetric. So let's make the same way the vertical line symmetric symmetric. Select the first endpoint select the center line okay now, my retainer is a symmetric with respect to both axes. So let's do the dimension, the horizontal dimension that is 114 and the vertical dimension is 82. So we already have the dimension, I will double click on the big dimension put the value Or use the vertical dimension 84 double click on the dimension sorry 84 and then this interpreter now required. So let's go to this case and see other features.

So, this arc of radius is 13.5 from this line. So the mission is 35 and 24 and this is 12 graded. Draw circle center. draw two lines. This line is already a tangent line. This is not a tangent line.

Here I have to make a tangent. So use a design constraint. Select the line, this selector middle mouse button. This line is a tangent but it is not horizontal. Okay, you don't see a horizontal constraint like this here. So come on, come on.

Let's define these dimension this dimension was defined for you. Let's define the radius Well, the radius is 12. So this is the dimension is already a radius. So I can define this only by defining divine 12 enter So, what I need to define now 24 actually this is not I need to define because, why because because I have a centerline and my circle is on the center line. This is a article. So this is obviously, up 24 if you try to define it 24 it will give an error.

So, let's right click the dimension Command click the first info, click the second point, middle mouse button. Why because the radius is already defined, so clear is not taking the extra dimension. And still you want to define the 24 I think you need to delete this constraint So, in this error box as well, results box as well, this horizontal if I delete the no I can do the 24 dimension because I had to delete the horizontal constraint. Okay. This extra line segment click feature another side if you want you can make use of symmetry or sorry mirror command for this because this is the same feature on the side. To use a mirror command first you have to select the entities and then select the centerline native mirror.

So, let's try to use a mirror command for cylinder It is with ctrl key. So this is what I want to mirror about the centerline. Now my mirror command is activated when by entities are selected, press the mirror command and then select the centerline. Okay, now I don't need to create the same feature. Again. There's another feature.

Let's create this semicircle feature and then we'll mirror it again and from the bottom and he's doing it again. We don't need to specify the state Or if we want to specify this country, then we have to create a constraint. So, the same way let's create it first you can zoom in and out pressing CTRL and press the middle mouse and then go circle the center endpoint command center and the point we did was bitten twice define the radius. So it is. So now it is diameter of 25 dimension, but you have to define the radius So, to define the radius, select the dimension command that is normal, and then click once only on the circle Click middle mouse button outside define the radius and create two vertical lines. Click the line Come on start point you can use a custom directly when you try to click on the circle select oh you just created outside vertical line and then we can make it so your options are now I use click once to sometimes you need to click two times a middle mouse button.

For example in the line command, sometimes with one click is okay. So create another line and created tangent okay You know, toys. No, these lines are not vertical. I just do the dimension of 10 here, which is in the drawing. Select the dimension command, post endpoint, an endpoint middle mouse button. I will love this dimension as well.

And this define this dimension that was mentioned. Yeah, this is a test. So we can define that I mentioned test dimension command center point line the most button see how the weird sketch is created? Why because we are not doing the vertical constraint before only right. So if we would have given the vertical question before then these strange skates was not created. So now I can do vertical constraint, first vertical cylinder line there's reading difficulties is externalized first This should not be 10 it should be 20 I think.

Yes, it's 20 because the radius is 10. So diameter is 20. Why because it will be 90 degree, and then this line will be 90 degree. So let's do vertical constraint with this line. vertical line resolve this Sometimes you also will face this kind of thing. I will create another line here.

Now create another line here. tangent line. No defined dimension from here to here. 20 Okay, no it is okay lock it No, we have an issue whenever we have to lock this dimension again again okay. So we have to do it every time right. So there is an option in the configuration files where you can select or you can select the option to lock the modified dimension and whenever you modified it is automatically locked.

Okay? So just see the process to do that. So first you have to go to the file, and then options. Click on options. And then in the options you have to go to the skater, the skater, the skater go to the diminisher behavior while dragging the selection. So there is option lock modify dimension.

Click on it and say OK. Click ok. To save the config file. Okay. Let's try if it works. For example, this is a strong dimension, but this is not locked dimension. Okay, no way modify this dimension. And then let's see how it works.

Double click on the dimension the dimension is locked now. So every time now you don't need to lock it manually. It will be locked automatically whenever you add this code to the dimension 20 again, back Delete this externalize delete segment command we have to mirror the same feature on this side. So we'll use a mirror command because you saw the efforts while creating this small feature as well. So to reduce those efforts, we can use a mirror command okay. So, the first thing to use a mirror command is we have to select the entities first.

If you see the mirror command now, here it is not activated, like those commands are activated, but this is not activated. This will be activated only when you select the entities okay. In my case, the mirror entities are is press Control key is now the mirror is activated and select the center line about which you have to meet in this case, this is my centerline okay. delete these extra lines. So let's go to this. Now what is pending is this four circles there are 13 mm, horizontal dimension, vertical dimension to 11.

So I can create these two circles and then mirror it on this side. So dimension a 1312 and it is to create a circle here clip circle command center point If you know you're creating a circle, just concentrate creo admittedly take some constraint now see the constraint taken it means this both circles are in the same line vertically you can select this constraint or if you do not want to select create a circle anywhere else and then you can drag it there. Or there is another option is you can create a center line. So, for me center line is the best option so I'll create a centerline to centerline and create a circle on that centerline. No, it is selecting that is in the same line at this point. But we don't need that.

So I just created circle the same radius or use the same question. So let's define the radius of this circle. The radius is for you. To dimension command. Click the circle, middle mouse button. Select the location, vertical location is 13 to 11, horizontal and horizontal location is 13.

So I can define this dimension 13. Let's make the circle equal with equal cost Click this circle in the circle define the vertical constraint or vertical dimension to this. The V dimension is from here, but we wanted from here this line. So we have to create a new dimension the dimension command center, select the line with Ctrl or Ctrl key and then middle mouse button. This is 13. Press Enter.

No I can meet up the circus on this site by using the vertical centerline. So first thing I have to do is select the circles. With control key select both circles. Okay, because I'm the normal command straight again. centerline okay. So my features are ready.

What is pending is this chamfer chamfer is obtained into 45 degree. Okay, so let's create a chamfer at the four edges okay the chamfer command directly in the first line here, the lens we can define the angle and the length So it is 10 into 45 degree, okay. In English let's define it define, define 10 employees define the angle. So to define the dimension, click on dimension command select the horizontal line in between these two lines. So my cursor is in between these two lines so click middle mouse button so angle is 45 degree and then press enter. So now I have to create the same chamfer at every places you can make use of mirror constant to make it easier Select this select the meter and select the centerline to centerline and create a chamfer it here.

So, I have selected these two chamfer please delete these extra lines come on because he there are some dimension which are big dimensions which is should not be no escape. We already have defined this dimension, but when we added a chamfer it is deleted. So we can define another way, or once again so let's define with this line and the centerline, the 13 point 13 or just log this dimension better. We already have a dimension here, I selected and lock it, select select, right click No, no, this will dimension right is before. Sometimes you're not able to understand why this dimension is here. So my trick is, I select any entity and try to drag it the problem okay, No, I think the problem is this dimension one on four and 82.

This is remote because we're creating all these chamfer entities and other lines, the references were deleted. Okay, so we define those entities and make them symmetric. So my horizontal length was four vertical lines. Select our horizontal lines. Mission command isn't just for constraint, this dimension which is not part of a sketch, I can delete this 84 dimensions these dimensions and make it locked, so they should not be change. This way my sketches really third exercise of the skater you learned because as much as you practice, you will understand more and as much as we do the exercises will make use of more and more commands.

Okay? So we'll concentrate on making the exercises as much as possible and as complete as possible. Okay, so Start today on this exercise, practicing. Thank you and have a nice day.
