So, Hi guys, welcome back to the next lecture our next video for the course, a quick guide for Korea apart design module. So, in the last lecture with the last lecture, we have finished explanation of several features and toolbars existing in Katia which are mostly used or exploited. Now, we In this video we will see how to develop a 3d model from a given two dimensional model the 2d diagram. So, this is two dimensional drawing engineering drawing for a particular elbow of this shape on these dimensions. These are flinches in between one is the pipe elbow. Now, he's here we observe it properly you must have a good knowledge of engineering growing to understand this in general mental level and reproduce that in Katia.
Now see that here, this is the side this is the side of you may see it this is a front view. Now, this flame external diameter is projection of this which is 150 mm, the internal whole from this part to this part through this cross section is 75 mm say for example 75 now, apart from that thickness this side and this side you observe that is some material. So, this is total is hundred from here to here this total pipe here observe this dimension hundred, so, this total is hundred this Tobin you say this total is 100 and that internal diameter is 75. That means remaining is 25 not 25 is distributed into two halves that is 12.5 thickness here point for thicknesses that means that this pipe is 12.5 mm thick shell shell type of tool. So, this cross section, this cross section of hundred mm external diameter and 75 m internal diameter is fee put 90 degrees from this part to this part up to here again he from here to here a dish straightline 50 here to here a district 150 once that is sweeping is done on the top surface, we have condemned thick flange here also we have 20 mil thick flange and on the flame just on this one and this one both We will do this six drills six holes each of 10 mm Daya and at the corners with you fi mm radius fillets.
So, let us try this in using Katia. So, let us go to Part design then select certain plan go to Scripture we need a circle and inner circle that means a circle inside circle constant two concentric circle inside each other. This is actually I'm trying to draw for pipe it is asking radius not diameter, since radius if diameter, here diameter is hundred, so radius will be 50. Similarly, one more triangle, I can offset use offset optional, but I am using directly when it is easier and I will freeze this as since internal diameter is 75 its radius will be 32.5. So, I will use that sorry, not 30 to 37.5 Sorry, I was sorry in the calculation. So, it is 30 7.5 right.
So, both are concentric about this center exit. So, this profile you have to sweep sweep from here to here in 90 degrees right. So, let us select this let us go to sketcher. Now, let us produce a central district should be 50 degrees 50 mm it is 60 years so, we want to make a change, we want to change it as 50. Now, we will draw a circle and use a trim option so, that finally, we can have the shape required radius we need radius here radius is 200 sweep radius. So, Patrick with 200 here.
So, doing anything wrong no it is correct find them okay. Now, let me make this point and the circle in tangency tangent, sorry tangency is not optional if a line and the circle as tangent Okay. Now, let me make this point and the circle coincident fine. Now, I'm almost there. Let me have a line here, horizontal line. Now let me use the trim option.
And yes, now I have what I want, I want it. Now you can delete the line. So this is what I wanted. Now Apart from this, I want to 150 here observe 150 here. I can do that and the slant should be 50 right. So, along this curve I need to speed this circle.
Now user profile is this one center is this one this is what we get. So now the game is not over, we need to provide flinches at this end and this end so select this surface and go to SketchUp Now draw again to circus and that I what I meant to say is under circle radius of it you can see since diameter is 150 radius will be 75 one more circle since its external range is external there is 150 internal dial 75 we need to do one we generate one more circle which is coincident with it internal diameter of the pipe so it's a coincidence Finally, now we have to apply a flinch No, we have to I mean do the material observe We need what how much thickness it is 20 so we have 20 Okay, fine. Now, apart from that, what we need is we require holes on this six holes so we'll do that go to sketch or go to hole, whichever is okay.
At a diameter of each hole is 10 mm so by default it is also 10 but we want two holes so up to last. Now we need to select the positioning of the sketch. So we'll do select this one and we'll select this one. We want it to coincide now we will select this one. Okay, now again one more, we'll insert this one Lewis heard this one and now the distance between them should be at work there is a bit when you observe here, there they're taking it by default some clearance from and they're having some bad press me didn't mention how much interior internally we have to take these holes. So, we can see by common sense applying common sense, we have to see that the holes, these holes are upside they are not matching with the original body or pipe.
So, to the upside how much portion is this. So out of this is up to here, this total is hundred. That means this 50 upper half 50 and this upper half is 75 means one half of 157 If I have 150 so this remaining portion is 25 in that 25 you need it mmm hold in 25 unit 10 mm hole. So five mmm about this material. If you try to take it, then still you're having 15 mm out of that 15. Again 10 is colder so five below the top surface, so you can see those things.
So you can so from Senator this total is 75 you need to leave file that means so is the center of the whole fireman, circumference and again from their center is five more. So total mmm you have to leave. So out of 75 you only need to leave 10 that means it is 65 right. So that's how it is now, let's Produce whole there. It's fine, absolutely fine. Now you observed it was absolutely fine for us, right?
This is a hole we wanted. Right? So it's fine. He didn't give me permission how much distance should be there here from Stagg room. So we are free to take, but with a bit of common sense we have places that this one don't call a drill through this one, I mean, it does not interfere this hole does not interfere with the main body of the pipe. So, we have taken care of that, right.
So this one we need to produce a six times that mean this first instance second, third, fourth, fifth, sixth Five more instances. So select that hole go in there, select the hole select circular pattern now instances I need six and six when they're in this 360 degree when it is six, then each should be 60 degrees apart reference should be circling which way either this one or this one whichever is fine. You can tell cert any surface same it is. Now you have this right. Okay. So you have this element, right.
So, I hope you're clear here. Now, now same thing you have to do On the top surfaces, that way we can do we will have a 45 degree line here or plane across this from there we can mirror it. So, that it will be it will come here it will stay here, similar to this as a mirror extent it will sum of one or more will be one more flinch will be applied here. So, let us try it, let us give it a try. So, we want the plane here at 45 degrees at the midsection, which is equal distance from this point as well as equidistant from this point. So, there are different options to create planes.
We're using this set here, see here, there are different ones one among them is through two lines. Right. So, for that purpose, first, we'll try to magnesium introduced directly go to the surface and create simple So, follow the same process as we have followed here at this surface. So, that is one part. Now, what am for that is anybody can do, because, because I have shown you how to create this from such a surface such a surface, I have shown you how to take this and extract this surface and go to scratch and create such a part such a such a HTML component or extension to this this part I'm showing you So, you can copy the same methodology here also and finish the part that is one way that is fine that anyone can do. Now, let us try some bit new, new way.
Somewhat another way to be able to use the command of mirror say there is display So that is this plan that is selected go to SketchUp then draw a line so, angle between that and this is 45 degrees okay. So let us level four to five degrees, okay fine. Now I have to see that this is at the center passing through the center of this total thing. So this line should actually pass Through a mid section of this to this part from here to here, so that I forgot to check that to enable to ensure that let us draw something like this and make it coincident with this coincidence Okay. Now one more access with this will make it a coincidence this one and this edge will make it a coincidence. Once it is done, we will use the trim option and we will use try to trim it like this.
Sorry I think this is Not getting deleted fine. So, this part and this point we will try to coincidence perfect. So, now this executive passes through the midsection right I will try to drag it apart fine. So, this is a line here which is passing through the midsection which is passing through the midsection of this entity. Now, let us offset display a plain palette to this and again have one more line coincident with this on that particular plane. So, I will show you what to do.
Let us have this one offset from one reference plane is this some are the other direction 20 mm Okay fine. Then let us go to sketcher for that particular plane as well and draw a line and have this coincident with this. Hope you are getting the idea of what I'm trying to do. Now, there are two lines for me right. There are exactly speaking there are two lines, two lines which are like this. Now I can create a plane which passes through these two lines right.
So, now I will have a reference plane through two lines. One is sketch eight, that is line one and another one is this one okay. Now I have the plane which I require. So, now I can apply this mirror mirror of what set a plane or a fish mirror of this is part one of the central feature circle that can be transformed fine No problem at least if the bodies transform then select a plane or face this one can solve it okay done not observe here So, this is what I wanted to tell you. So, it is a bit you might be looking at it as if it is complex, but if you are well versed or practicing, it is very easy to create these lines and passing through these lines. It is easy to create a plane And just a mirror option it will immediately come like this right.
So, so that is how it is. So, you can hide them in order to can hide them. You can even hide all these things. Hi, all things and even in this reference plane as well. Now this is the part that you actually required Right perfect. So, this is what actually will require Hope you're satisfied with it.
Now, if you want to see several views of it see here, this is the one it is already there. And this one actually say for example, I want I want a server separated you know, rotating it is the only option So, these from these two are there which you already have in the diagram. This is this is an isometric view this is an isometric view these are some other views. That's it. However the normal view you can have it. So, one thing I forgot is to give Phillips so any to you Philips have right.
So where are the dresser features just come on, come out. I don't find as a features here. Then I had to take them from here Tricia features so from there and what is the filler diameter he's saying so, it is racist file. Now let us read his file object to fill it is this one fine tangency it is fine then Okay. Okay. So we've got it right, we've got the flat similarly, we will apply here as well.
So, one more fit a fireman de radius at this edge fine. So this is the final part we wanted. So that is how we need to do. So let us save it. Fine, thank you. So, this is what I wanted to tell you how to do the things and not so with this.
I am this session. So, in this in the next session, I will explain one more example, that will be the end of my explanations. After that, I will give you three models or three diagrams for your practice purposes. So, that is all. So, this one this diagram this 3d model had derived from a 2d diagram, 2d drawing. Next one I will develop from isometric view that is 3d sketch, I will develop a 3d model.
So, these will be there. That's all for now. Thank you for sticking with me.
