Hi guys hope you're doing good Welcome to the next lecture for the course, a quick guide for Katia the part design module. So, in this video we are going to generate this particular model in using Katia software. Okay. So let's go ahead. So, this is the part design module. And he observed here that this is the exit direction.

That means, we can take x ray as the base on that we can develop in jet direction this particular module right. So, first observe the dimensions here, this is 23 radius, this is 10 radius, this is a hole This is 23 radius means from this is 23 This is 23 total is 46 on that 46 we have to have a semi cylindrical surface to that further something is attached to that this particular object and so, to one there is a link between each and everything this is completely totally a one single part. So, we have to have a crude or preparatory phase of model first on that we have to apply several features of Katia So, that we can have slots here decide this there are pockets you can see this side this side here and here. So, like that, so, that is one way. So, let us proceed first first let us draw this one.

So, first let for example so first let us how the data diameter total diameter of this one is 60, externalise 60. So, let us have a cuboid of diameter 60 and height 60 then on that we will height 60 diameter 60 So, not diameter sister sorry breath is 60 a height is 60 and the length Let it be here it is 15 plus a 60 it is 75 sorry okay from here to here this the center it is 60 and from again this center to here it is 75 So, 7060 plus sorry if 75% of 150 or two here and again here 23 additional. So, how much is that total So, it is 150 Plus 23 that is 173 length. So, how to generate a keyword of such sort first sorry, first we have to go to sketcher. So, this is x axis we are looking in this direction.

So, let us have a rectangle self centered rectangle let me use a self central rectangle take origin as the West origin as the center. Now, I can fix this length length I have what we got was 173 and what is 60 now we have to pad that to a height of 60 So, this is what we have got. So, this is the cuboid we require on that observe here, we need to apply the features from top side and have these features as it is here one pocket here one pocket here this pocket and this is a stiffener and the bottom side also we have to apply on pocket. So, there are several ways this is one of the ways I have and trying to tell. So, let us set up the top surface go to Scripture now Select a polyline want to completely remove the material to certain extent, let us draw a circle whose radius will be 30 because its diameter is 60, our external diameter is 60 we need to have its radius as 30.

And one more thing displacement of center from this end will be this 23 plus 75 that is 98. So that center from this edge has to be 98 and one more thing is this one will be coincident with this as that is. This one will be coincident. Okay dun dun dun dun. This one will be coincident with this. This one will be coincident with this.

We have to check that we have to break the circuit first. Break it this one along this way axis No sorry, we didn't get the break it break this circle at this point. So, this is one part this is one part. So, now, I want to mean option go for trimming, select this part and drop it. Similarly, again go for trimming select this part and go for it. Now, this is the sketch, we have obtained, this one we have to apply pocket for this sketch, we have to apply pocket up to what extent after depth of 45 because remaining 15 is material is there.

So, apply pocket 45 Right so that is the initial stage okay done. Now again for this surface go to sketch. Now we have to remove certain more material, because this total width is 46 but our cuboid total width is 67 from here seven from here we have to remove up like this and here we have to have a curvature, this curvature, So, accordingly we will do the things okay. Now, we will fix distance between this one and this one as 46 first then I will fix this one and this one a distance between them to this minimum. Now seven plus 46 plus seven that is 16. And this is our key has to be tangent to this particular edge fine.

Now, one more thing we require this arc some arbitrary way you do later. Now, let us make this one and this one coincident find now Let us break this are this are about at this point. Now, this is one part this is another part. Now, let us apply trim option in other software's trim trim and this trim option is separate and extend option is separate but here in carrier we use both for the same purpose. Now, we have this particular thing Sorry Sorry. So, we have we want to remove this particular material not this particular material.

So, to remove this we must have a profile like this percent not in internal interior. So, this is not what we require externally Sorry, I have to delete this and this one I have to of course, draw an arc and how that one and this one as coincidence right. Now, of course, I have to break it up to that point it was fine this one I had to break it at this particular point, no fine, this is in separate part this is one separate part. Now, this spring I have to use in a separate way not internally or externally. Fine, no. That's it done.

This is a closed sketch observe me doing a client pocket for that I want to last See, you might be seeing it right. Otherwise one more thing I could have done was anyway I want to remove this one also of radius 10. I want to have one circle, which is at a central distance is at continuity from this and so I can have that circle at a time. That one also here at certain point sorry cancer search radius is 10 and is the center distance anyway we know it is 23 that anyone will know. So, we will not apply because I have made it coincident with this external circle so, it will automatically be added there. Now, for that we want the pocket, right.

So, this part I got, again set up this surface, go to sketcher not apply a hole here, this one pocket and this one another pocket This one another pocket. So, there are 123 pockets multi pocket I can use Let me have a circle first and let me make this coincident with this done no one's I have sorry, what I wanted was not this one I want okay okay anyway I want that circle as well one more circle Acme draw internal circle whose radius is 20 that means, since diameter is 40 radius is 20. So, now, I have to apply these pockets right in between 10 min 10 ama material is there. So, firstly Let me draw two lines between them like the distance return and distance between this electric bracket this side or this is calling for this. Now I can do it this one and this the center distance will not 3.4 it is five.

So file that is one part. From here, I want this is 15 So, from center, I want to a center from center, the distance between these endpoints of these lines shall be 60. So anyway, we'll see that now, this must be coincident with this. Now, I want I would like to break this external circle, this external circle at certain point. Now this is, this is one part is a separate part. Now, I can Use promotion for this part, again promotion.

This part I can use this and one more time this sort of So, let me make it tangent to do this one okay done. Now, distance between this one and this one is 15 similarly distance between this one and this line edge is 15 fine. So, this is set this is set. Now I would like to again apply trim option to the circle for the spot. Again I would like to apply option to this circuit With this part So, this is one sketch, this is one sketch. So, within the sketch this is one part, this is one sub part, this is another sub part.

So, let me go back to sketcher and apply multi pad this time. So, here observe this part, this particular thing is one, this particular thing is to this purpose at least three for one and this two for one and two is one and two what I want this depth So, what is what does he say this is total is 45 in that this is 15 that Miss arrow is 30 So, I wanted the top 30 For this third one, I want a true hold that means total 60 Okay. So you have got something like this right. So we have some more work actually. So we need to go to bottom side now and go to Scripture. Now we have to do pocketing at the bottom no apply circle which will be concentrate with this Also actually not acquainted this concentric concentric city should be applied and its diameter we know 60 So, radius will be 30 fine.

Now, we want to break this circle first at certain point, this is some part this is some another part. Now, I would like to apply tangency for this and also I would like to apply tangency for this and distance between this sorry have this be 60 This is what we got. Now, let me apply to this. Similarly again a platinum option for this part of circle with this novel got this one. So total is 60 in that this upper part is 45 minutes remaining pocket parties 15 So, we exit the workbench and we will apply pocket, simple pocket and we will do it for 15 minutes in the direction in which it is reading so that I write or get a bite pocket amen What's happening out there? I would like to apply pocket sorry It is up to large Nautilus to be one dimension and that is 15 Okay.

So, this is what we got almost we are the only thing is I had to apply these to apply these two holes and how to apply this stiffener directly to that as well. So, these holes are at the center distance of 35 mm and their diameter is 16 mm and from a top edge they are at 59 depth. So, let me select this hole on the surface is damaged Is 16 diameter is 16 that it is through holes of 15 positioning, I need positioning from this top edge this hole is at 15 mm down downwards 50 down and also this total is 35 total is 60 in that 60 this half part is 30 and this on 35 half is 17.5 So, 30 minus 17.5 it means 12.5 well point five So, from this edge it is 12.5 mm distant. So, now we need to apply a hole here.

Fine to this we can apply a rectangular pattern. Only two instances including the original one one more one we want spacing I want 35 mm reference direction. I will apply this one and in the reverse direction hole is four Hope you're clear how I have played there. Now, that is when the only thing remaining is applying fender. Select the surface go to sculpture distance of this and this otherwise I can say this length is 10 mm and also I can I have to freeze distance between this one and this line is fine fine. Now, I how to draw an arm or a circle whatever is appropriate for me from the heart related coincident with this from the I have to break it or else I can do one more way instead of breaking this I can extend this Like this Like this an epic could trim that is also possible for us.

So, now I can delete that. So, I can quit on this. So, I can trim this part I can trim this part sorry No I can try to apply for this. Okay let me do a review that says please, yes, this part is there. Now. Now, length of this actually, the length of this part is 25.

So, let me phrase it as 25 Alright. So, let me exit the workbench. Now a play by the command up to a height of our length you can say is 45 mm sorry it is in reverse direction I should have done it in reverse direction Okay. Now I have this on this and now I will apply another pocket comment in this way. Let me go to sketcher Let me hire a polyline Now, let me Apply coincidence constraint would like to apply pocket for that. That's it.

So this is the part that we actually were craving for to develop a 3d dimensional geometry dimension we can observe here Right. So, hope you are clear, we can have several use also for this. So, that is all for this class and this will be the end of Katia part design modules course. Now, I will give you some practice, designs or I can say 3d sketches for practice. You can find them in the practice session or assignments section. Thank you
