Hi guys, welcome back to the next lecture of the course, a quick guide for Katia part design module. So in the last lecture was all about the dresser features in the part design. Now, let's get into the operations toolbar. entities are different features of operation toolbar in the sketcher module in this video, so let's get to the part design first. Now, once we get there, let us get to the sketch select certain plane and get to the sketcher module. Now say for example, same some there are some operations.

So for example, we have a we have an arbitrary rectangle of some arbitrary sizes length and breadth. Now say for example, you don't want the sharp edges in earlier stage in Russia features once we have developed the total part then we have applied fillets to the sharp edges. Now, before in beforehand itself we can develop the rounded corners, so, that we can avoid applying fillets later on in the data space. So, how to do that. So, that option can be done corners in the sketcher module in the in the 3d workspace when we what we were using was fill it here we are we can use this corner. So, once we select the corner it will ask us here to select the first ticker or common point for e i want here the rounded corner.

Then common point is this one. From that I can generate curve, rounded corner whatever is possible, say for some arbitrary arbitrarily I'm selecting and clicking their son some arbitrary radius computer Point 933 it has come. Now, I don't want this much I just want firemen. So, first I need to provide this dimensioning for this otherwise they will change. So, as we will be knowing actual what will be the sizes of our component we have to freeze them say for example, this is hundred and for example, say this is 50 Now, once that is done now we can adjust this radius fill it radius there in part drawing it is fill it in sketcher model it will be a corner instead of sharp one we are having rounded one if you said JIRA it will not take so it is taking it will be sharp one as it is but now that corner radius if you're adjusting say for example five this is what it comes is not visible, clearly.

So, let me yeah I hope it is clearly visible appearance for appearance purpose in order to enable you to clearly let it make it 10 See, this is the rounded corner, that is one way in part design we have developed chamfers similarly, within directly in a two dimensional sketch itself we can develop the chamfer surface see by selecting this chamfer option and selecting this common point, I can select arbitrarily To what extent I want to chamfer say up to here, it is impossible to Tamil entitlement because I have given 100 mm as the length of that particular length of that particular line segment. So, it cannot remove this part. That's why it is showing this point. Now, if I say that just this hundred be the distance between this phone and this line as a distance, if I say yes, then it will be trimmed now Here the problem is from here to here, you have to apply constraints separately or else if you know a chamfer length it is the best you can directly say for example, say 10 by default will take 45 degrees chamfer so, that is a part.

Now, for example, let us develop a part here, 3d, no padded once Say for example, don't want 2130 either you can enter 30 here or as limit to one by default first limit is asking. So, here limit one limit to order limit one increase arbitrarily set 3030 or is directly going into 30 year whatever it is. Now, observe here this is a Phillips rounded corner and here chamfered corner edge you can see So, directly we can incorporate integrate these features in two dimensional sketch itself before producing the three dimensional Also we can produce a three dimensional one from the basic two dimensional sketch and then apply this fillit and this using the sketch based the dress of features, right. So that is one part. Now. Let us go to the next one few more options, I don't want to save it.

Go to part design. And now here Go to sketcher. Again I'll say some arbitrary shape is there. Say for example, from here you want a car it is actually coming straight linear. Instead you want a curve, then you hold the left click and try to drag our roll or scroll your touchpad, scroll on your touchpad And then release your left click then then it automatically will come like this and you can adjust the radius by scrolling left or right up down etc The amount of curvature you want. So, I want like this, then once once click there, then the circumference will be fixed after that you can probably proceed further for the next line segment like this Okay, this is a close to one.

Now, otherwise what we could have was something like this something like this. But now what I want is I want this part. So, I had to delete these two things. There are several ways, one ways trimming it. So, how to trim this is the trim option here Good thing about it is first you select which part you want and how you want you want like this or you want like this you want like this. So, you select other two these two parts are automatically deleted or trimmed off right.

So, that is one part or else you can do it another way is not trim break. So, for breaking which element Do you want to break this element you want to break this element both elements you want to break at what point despite So, one by one we have to first break this element here at what point do you have to break it at this particular point, intersection point. So, sometimes it may give you a wrong because for appearance purpose it might be appearing as if it is intersection point some but when you zoom in, it may happen that it is slightly the same or slightly This is a slightly up or slightly down. So to avoid that it is better to use trim option but For showing you how we do generally I'm showing you this so I'm breaking it here. Now observe here this is separate part this is separate, but earlier it was a single line segment now it is separate, but now you can simply delete it.

Similarly here if you delete it complete line segment will go off soon we don't want that you want only this much part this upper part about this line to get deleted again you select the break command No sir the breaking element where you want to get it broken at this point. Now this is separate but this is appropriate now you can select this and delete it. So now observe whether it is open or closed, now you can check it once your parrot has come. So means you are breaking element you've selected it properly the intersection point was what you have selected. Okay, done. So that is how we can select the trim break options.

Let us go back to school. To check again not others for options available here is some other excetera. So, again go to Scripture that is one part. Now, again let me draw this part. Now for suppose sorry. Now, this is how it is.

Now first you break it this element at this point now, you need not select this then again right click and delete. You can directly use this part but if you use quick trim for here it will completely get deleted. No sorry If you want to trim at this point, you can select it first, then if you want to trim it, it will understand on which side it will itself take, because trimming. Trimming means in general actual trimming traditional was trimming means, it will select which one object you are trimming and what should be explained or limiting. For example, this one you want to trim What should we it's limiting line or limiting direction this line so, you want you were trimming like this earlier. Now, the same thing if you look quick trim trim option.

Now, let us say it is a complete line segment here also it is complete line segment no trim option is selected. When you delete it, it will itself select this part you want to erase up to this line. Similarly, if you select this trim and click it here, it will add This error is this one up to the spline. If for example, you want this line, but you want delete this line, go back sir erase in click on this side of this line, other side of this line, then that part will be deleted now you have what you want. So, that is what other options are there which we do not use generally, these are the things we use mainly. Now, some other options are scale, mirror etc.

So, to make you understand about mirror and symmetry, let me draw an axis first. So, this is some arbitrary axis. Now, Mirror Mirror, if you have completed your plus one plus two level or you can say Higher Secondary classes in your education, then you can understand what is the mirror productions. So, in that this is the same thing we read. So, now, we want need To select which element to do you want to go here select sketch here it is not you are able to escape. So, you select from here, actually what you will do, you will left hold of the left click, you will drag so that the entire object is inside this box, then it is completely selected a circle geometry selected.

Now, about what access Do you want to have a mirror of this particular original element about this axis, then this will stay along with this. It's Miller complimentary object mirror element we'll be here is visible, this line is nearest to this axis. Similarly, its corresponding line is this one this will be illustrated this axis this arc is farthest or farthest element with respect to this axis. So, its corresponding artists this one, this one will also farthest from this axis that is what we mean by mirror extent Okay. Now far suppose for the same element we are trying to apply symmetry using this axis symmetry. Now, which element Do you want to have a symmetry this total element is not selected see because box was not entirely close in closing this object now it will be selected completely let us uncheck it, then select it completely such that the total entire object is inside it.

Now, some symmetry now select which x is about this axis. Now, in symmetry what happens the original entity disappears and symmetry mirror extent of it comes which is symmetric to this particular element to the other side of this x, this is vertical So, you know I think you are able to understand for example, axis is not vertical it is at certain inclined position. So, let us see that possibility as we say for example, axis is somewhat like this incline. Now, you want to make a mirror extent for this, for example, say first select this entire object. Now then axis about which you want mirrored action. So, this is nearest point to this at the same distance at the same angle this side you will find this point similarly, or broken line you draw perpend line perpendicular to this and such that it touches this point, same at that particular same distance from that same point here, this point will lie that's in that way, you have every point corresponding to it on this side of this axis.

In that way you produce the mirror shape of this original part. Right. If you were about to apply symmetry with this access to this object, it would have been disappearing and you would have final object as this one that is just a difference that is about similar and symmetry. So, let us have a small object here say for example soccer now, you want to apply translation to this, you want to report from this point, how much forward or how much backward how much up or how much down you want to translate this circle, the translation you want to apply not applied. So, this translation means, generally this geometry to be translated I have directed this geometry now, we have to click certain point on this field on this workbench where from with respect to which we can measure distance up to what extent linearly it will translate.

So, for example, you are selecting start point as this. Now as you translate in this direction it will give you the data section I have selected three instances. So, three more will come this is the original one, three more circles are there three instances repeating. Now, I want the transition to be in a horizontal direction, it will be like this, I want this to be at a certain angle, I want this to be vertical depends for suppose your translation is just to that automatically it will be to to surface for suppose if a translation is one, you certainly will one for suppose your position is zero then what happens? First suppose you trust it further suppose you've translated new instances is one I hope not I hope it is minimum instance has to be one Now, we want to translate it in this direction, it will be somewhere like this.

Though you make it zero, it won't happen because one is the minimum by default value. So, it has to be minimum one. So, you will have the original part Apart from that, you will have one more part A translated part. So, this is a translated part no for Suppose, you want to rotate it about a certain thing for translation, selecting your point and translating in a particular direction will give you along that direction, the number of translation instances, no rotation. So, now, let's rotate to see the Rotate option instances to set this entire thing. Sorry, I'm unable to select the template mouse to entity selected about which point to rotate about to this point it should rotate in with what is the reference line I want to say for example, horizontal line x axis.

So y axis with respect to this how much in order how much degrees it should rotate. Say for example 24 degrees then, so this is the original component. Now, this is second set, this is third set, you might be wondering, this one I am going to see one, these two original what this is first instance this second instance, but for this circle you're unable to see its first and second instances because it's second and you're rotating it about its own center. That means, and you made me numerous times, rotate the same set it all circles will coincide with each other. Right. So, can observe here, subtle threes there circle to circle three circle for kill five is also there.

So, three circles coinciding on each, but this circle to circle six and circle seven are different. Now, you want to if you want to see this this kind of distinction here also. Now, let us go back let us go back. Now, let us again apply rotation Now select the entire thing. Now, instead of selecting this as a rotation point set support you rotate about this point. Now, the reference line letters displayed as this non observed So, two instances So, this is the original part, this is first set of first instances.

This is setup second instances that is the rotation part not scaling scaling is the next one. So, let us go back scaling select scaling. Now which entity you want to select, say for example, sorry this entity you want to scale. Now, well what about which point about this point this point this point or which point he wants to quit. So, for example, about this point you want to scale how many times minimum point one maximum you can do go to any extent Say for example, two times and right. So, I hope you are able to understand it.

So, scaling is done about this point. So, that's why you are seeing some offset between it's bigger on center and this one center. So, from this point, center is ingesting itself such that the overall circumference is two times. For example, don't worry Like that you want concentric circles scaling has to be done, but concentric only there is an undo and now again go for scaling. Select the entity which you want to scale. Now, select the center about this point you want to scale.

So this final entity will be concentric, say two times the same radius same diameter, scaled this surface scale two times of its radius. That means the first suppose if it is how much So okay, so for suppose its radius is 28.284. There's this belief 56 point something in that case, because it is See 56.5 set 569 So, it is scaled two times off its original radius. So, that is a scaling our ad scaling up scaling down both both are possible you have seen from 0.1 to any extent you can go to scale scaling down and scaling up. So, that is one but another one is offset say for example offset you want to offset this particular entity for example, say click a point of locating the new element. So, you want to do the offsetting inside or outside that is of your wish.

Right. Say for example, I want to offset this alright. So, that is how we need to offset not actually here. Certain things will be there. Oh, Boss customize the store positions. Okay, close actually wanted this one gets to use my geometry constraints construction standard elements dimensional constraints just the scale on directly scaling it down, right?

Scaling it up, scaling it down, up, down, up, down. So in that so now let's leave those Jokes apart. Now let us try it right so what are transformation features This one offset when I set it offsets you are able to see that here few options are there. Now, if you want both sides offset downwards and upwards it will come both sides. Now go no propagation, tangent propagation, find propagation Point to Point population means the total entity will be propagating this I will show you with another example better because circle will create some doubts in your mind because it's completely symmetric symmetric about the center each and every point. Let us take say, one entity.

So, for example, this one now for this you want to get an offset situation, say select offset. Now, this one is no propagation that Whichever entity you select, only that only get offset the set of this how many instances you want say for example, five instances. Okay and offset distance. Say for example 510 2030. Anyway it is adjusting itself, so five instances you want. So select that.

So for instance 12345. So that's how you got offset. So for example, you don't, you just don't want only this one, but you want this up to here. Here, this tangency point, this one, this one up to here it is 10. So this total set you want as one, again, select offset. Now you'll see tangent propagation is there.

Then select this one, this total thing will up to where up from this line and to this line, whichever is a tangent, that entity will also come under focus. Say for example, you want two times And you want off status and you wanting upward that two times two instances this has come first suppose you want the total entire thing to offset that against offset. Now, you see by two point this is point property every point will get offset any entity you seller here is complete thing will complete geometry will get offset say to instance as a here and select surfer was 10 instances and a distance of 10 every point from this point to this point 10 from this point to this point. So, every point is offset at 10 and again from there again one sector more and so, first instance second instance that is how it is now for now, presently offset is being on one side only once upwards and downwards Then in select offset, you said this one as well.

Now for example, select this one as well. Now, insert an outside by default is coming in say annum irrespective whether I'm taking it outside or taking the cursor outside or taking the cursor inside, but the actual geometry is being offset both the sides. So, I only want one instance for instance, it will leave us traces of the geometry, both insert as well as both outside one set of insert one set offset, one set of points in set one set of points outset here for example, two instances, there are two instances outset two instances inside of solution is correct with this much because geometry will collide with itself or contract with its contrast with itself. Say for example, three mm and say Inside two instances, outset two instances. So, that is how we have to use this offset feature, this project 3d elements is a bit complex one.

So, this is not the right time to know about it, I will tell you in the later stages as per the requirement. So, thank you, that's all for this lecture. Thanks for being patient and listening. So, let's continue in the next lecture for the further concepts on the transformation features in the workbench of 3d part design. So, these features I will just show you, which are the features that I wanted to discuss about. So, here I am unable to see them.

So, I will select the toolbar. So, actually what I was discussing about this transformations Transformation features. So, these are the features versus develop 3d parts for example, pad this entire sketch 20 mm, something like this has come to this I want to apply several features such as mirror. So, earlier in 2d sketch, we have already applied some operations features such as trim, mirror symmetry etc. Here the similar lip we can apply this translation features such as translation, rotation symmetry etc. And later on you can also apply mirror otherwise you can also apply that rectangular circular and use a different patterns or else you can do scaling as well which are mainly we will be using pattern fields mirror and some translations.

So, these things we will see scaling we will say depending on the requirement. So, let's meet in the next session. Thank you
