SOLID GEOMETRY PART1

本站添加: 2026-05-12

[00:00:00]Okay. Uh this is your paper one, question two, which is going to be your solid geometry.

[00:00:13]So whenever you're going to do this drawing, you have to remember it's going to be always your top view.

[00:00:26]Then also it's going to be your Okay.

[00:00:29]This is your front view here. Then that is your top view here. Then it's going to be your right view on the side.

[00:00:36]That is how you always have to it's always in the first my first angle.

[00:00:48]So we are going to start by what is given to us here by projecting exactly as it is to go on this side. Then after that we are going to do our top view protecting from this front view given to us here. Then we can get our right view also.

[00:01:10]Okay. I'm not going to read the instructions for you but each and every time I'm done doing something. If I'm done with my given front view I'm going to tick here. If I'm done with my sectional top view I'm going to tick here. Then also I'm going to tick for my right view.

[00:01:28]L says they're planning essential also have to show the all hidden detail and also need to show the constructions and the scale is one to one. Those are the things that you need to pay attention to. At the same time you need to show what the auxilary view at the same time pay attention to your cutting plane. Okay, let me start. um by doing that. So this is 30° here.

[00:02:14]So So I'm going to use this angle here on to do this part.

[00:02:21]Okay.

[00:02:24]And this side that is 60.

[00:02:28]So let me just cut this.

[00:02:34]If I start here on this point, I go this side as 60.

[00:02:42]And from this point to this side, it's always going to be that 70.

[00:02:48]And again, yeah.

[00:02:56]I need to measure from here to go up by 70 mm.

[00:03:07]Okay, this is India again on the side.

[00:03:19]that that is going to be seen here.

[00:03:28]>> Then I'm going to close that.

[00:03:37]I also need to close point here which is now I can make this as Dark points.

[00:03:54]These can be my dark points here.

[00:04:06]These are my so I'm do exactly what is given to me which is what I have here.

[00:04:18]Then now from here to here that is 70. So 7 / 2 is going to give me 35. So I'm going from here to the center here that is 35.

[00:04:34]So I need to look up for my 35.

[00:04:42]That is my 35 here.

[00:04:47]So on that 55 I have construction and again um from here to here that is 20 mm.

[00:05:20]Then again from uh from here to here that is 10 mm. So I'm going to be half here on that 10 on that 10 which is going to my y on this side.

[00:05:43]That is going to be my x here on top.

[00:05:48]Then on this one I have here I know the hexagon here it side here it is 35.

[00:06:01]So I need my compass to open up by 35.

[00:06:10]Let me open up my canvas by 35.

[00:06:17]uh 535 which is going to be somewhere here.

[00:06:26]That is my sender. Yeah, my sender is going to be here.

[00:06:41]So from here to here that is 35. So I'm going to do a segian I'm making a segia which is 35. So from this point here, okay, from this point here the bottom which is this one here also from here to my left hand side 35 to side and 35 again from this point here to go up there it's going to be 35 five here also from here to there that is 35 which is the same as from here it's going to give me to that angle also which is correct there so what I'm going to do I'm going to join this point this one I'm going to join the long one that's on the side other side that side it's going to be a dark point I need to M squ them same as this one I'm going to join Yeah, that one is going to join there.

[00:08:33]And this one I'm joining together with that one.

[00:08:42]It means now each angle here is this 35 from here to there. 35 35 from here to here. 35 from here to there 35 from here and 35 from there to there 35.

[00:08:59]So now I have my hexagonal prism.

[00:09:06]Now I need to do a circle that is inside here which is the diameter I have which is uh that is 50 from is from this point to this point there that is guys I'm making noise man which is my diameter for this part here second which is going to be 50 it means now I'm going to open my combass by 25ide by two which is give me 25 as a radius.

[00:09:45]So the radius for that 50 25 let me open my compass by 25.

[00:09:59]Let me open up my canvas by five. Then I do a second.

[00:10:05]Now this second line needs to be dark because I'm going to use it. Okay. Then now I have my circle as 50 the diameter.

[00:10:30]Okay.

[00:10:31]Now I'm going to join these lines. This angle and this angle goes together. So I can just take this one here as a construction to that side.

[00:10:43]Same as same as this one and this one goes together.

[00:10:49]Then I can take this angle here.

[00:10:55]Then now I take this one for this circle here.

[00:11:02]I stop here. Same as the one the bottom >> to there. So what am I going to do now?

[00:11:16]I can give you my cutting plane which is going to thrust here.

[00:11:26]that she is going to thrust here on this point here.

[00:11:35]That is my cutting plane. I can have this see here.

[00:11:41]I can have this se that is my cutting plane.

[00:11:52]That is my cutting plane there.

[00:11:57]So once I have that cutting plane, I also need to have the dark line what I see here which is this line here.

[00:12:10]That is the dark line.

[00:12:12]This line here and the dark line. And remember this is a it's going to be a center line. Yeah, it's going to be it's going to be long. Yeah, a short line. Long short line and long.

[00:12:38]So now on this circle, I'm going to make up this corner.

[00:12:48]So from here to there again it's going to be like that is going to be like this. Yeah.

[00:13:18]That is it.

[00:13:26]>> That is what you going to have, man.

[00:13:34]I do not use other words.

[00:13:40]Okay. So, that is how it's going to look like.

[00:13:44]That is your given front view.

[00:13:49]So whatever I have here is given to me.

[00:13:53]I also have it on the side. So if you can check here, this is out of 36 marks. So the given front view which is this part here number two here that five marks here. I already have that five marks here.

[00:14:17]Now what am I going to do? I'm going to give this numbers. So, I'm going to say this is one, two, 3, 4, 5, 6.

[00:14:42]Okay. Then, um, so whatever I have here on these angles, I also need to have it on the side. So this point here, this point number one. So this point number one goes along here on top. So here I'm going to say this is my one here. Same here. That is one here.

[00:15:05]Same this one. This is my four here. I'm going to have the point number four here and point number four also on this side.

[00:15:14]Again I have this number five here.

[00:15:17]Number five goes with number three. Let me verify that for you.

[00:15:23]Let me verify that for you so that whatever I'm saying, you also can vote for it.

[00:15:38]As you can see, point number three goes to point number five. So I'm going to have five three here. I'm going to have five three here. Again on this side.

[00:15:58]Same as six goes with number two.

[00:16:09]Six goes with number two. So I'm going to have point number six here. under.

[00:16:16]Oh, okay. This here supposed to be here.

[00:16:20]It's supposed to be here.

[00:16:22]Not here.

[00:16:26]Then again, it's going to be six slash two here.

[00:16:32]Uh, let me try to bring that close to you.

[00:16:39]Let me try to bring it close to you.

[00:16:42]So this six and two goes together all along from six and two here again this point here five and three goes together it's going to be five and three here together this four here this four inside this one here this one here so now I have what is given to me which is the front view now in order for me to do the top view I to do the top view. So whenever I'm going to do the top view, I'm going to project what I have on the front on the front view.

[00:17:25]Let me start by projecting the point number one.

[00:17:40]boy number one all the way down.

[00:17:44]Um I'm also take this last one here. Point number four.

[00:17:55]Again I need to protect whatever I have here.

[00:18:01]Let me start with the square first.

[00:18:05]uh that point number one there on top otherwise you're going to project everything that you have from the top view.

[00:18:24]Everything that you have your top view.

[00:18:28]So let me use these numbers here.

[00:18:34]Five and three.

[00:18:37]Five and three. Yeah.

[00:18:42]Six and two.

[00:18:46]Six and two. Yeah.

[00:18:51]Okay.

[00:18:53]So now we are going to use our canvas and also this XY line here.

[00:19:04]This XY we have here uh how many minutes now? Okay, 20 minutes.

[00:19:14]Okay, so as much as I'm going to open my comments from five, let me start from four. from point 4 to this point here from all the way here to here.

[00:19:31]So my comes from four to this point here.

[00:19:38]That means that this line here, this line for four, this line here. So I'm going to use this point here.

[00:19:49]Okay, let me make I want to make my drawing a little bit neat. So let me move from this point here to here by 10 mm.

[00:20:03]Then I can vouch for you that uh this is going to be my um x-ray this point here.

[00:20:18]So I'm going to use this from this point number four to this point here. Again this point number four here this line here.

[00:20:29]So from here I can make a point here which is this point this point number four from point number five here.

[00:20:53]This is my line from five from here.

[00:20:58]So from here that is point number five.

[00:21:08]From point number six, point number six.

[00:21:16]Point number six and point number five.

[00:21:19]See the same. That's line here. That is line for point number six.

[00:21:27]That is my point here 6.

[00:21:32]Then I have on this side from here to that point. Point number one from here to there it's point number one. Point number one and point number four is the same here as I have point number one here.

[00:21:49]Point number one here.

[00:21:54]That's my point number one.

[00:21:57]Yeah.

[00:22:00]Again on the side.

[00:22:04]Point number two.

[00:22:07]Point number two is here.

[00:22:10]Oh, remember I have two ones. So I almost forgot this point here. Another one is here.

[00:22:19]So it's supposed to be also and the same here that is point number one here also for point number four there are two there are two of them also let me try that point here to there and this is point number four line for number four which is from here also That is point number four.

[00:22:52]Okay. Now, okay. Um, so it seems like we need to extend our lines here, which is going to in this way.

[00:23:18]That's why this one here.

[00:23:22]Let me extend all of them actually.

[00:23:34]Let's just extend all of them.

[00:23:38]Yeah.

[00:23:43]Okay. Then um so we have four 5 6 1 4 1. Now we don't have two and three. So it's going to be like from also from here from two to my XY line here which is there um from point 2 to here.

[00:24:11]to here.

[00:24:13]Then also my tool in this side. My six is here. Then my toe on this side. Then also from here this point here.

[00:24:36]And my two my two is going to be here.

[00:24:45]Oh, you can see that is two here.

[00:24:51]Again from three to here the same distance. So again my three is here.

[00:25:06]That is point um point here.

[00:25:12]My three is on this side here.

[00:25:18]Then again on this side I have that six here. Remember what's up from here to here?

[00:25:28]Let's sit down. From here, from the side here, I have like six again. So from here to here, look at this point here to this point there.

[00:25:48]That is point number six.

[00:25:51]I have six here. I have six here because six also goes here. Goes that side. Then I have uh two here. I gave myself two on the side which is from here to there.

[00:26:14]going to be the same as in this line that two goes that line there.

[00:26:23]So from here again to the side there that point there that is two then also I have from here that is three to the center again I have that 53 here. So I must have go all the way down from here to here.

[00:26:50]But this point here that is three.

[00:26:54]Then I have five from this point here.

[00:27:01]It's going to have that line for the five here which is that one.

[00:27:11]That is my point which is point number five. So what I have actually is this way I have on top I have uh start from here five six then there is space inside I have 5 six. Then on the bottom here which is the middle line which is 1 4 1 4. Then our bottom part which is this one here I have 3 2 3 2.

[00:27:44]So what I'm going to do I'm going to join these points together all together in construction. So let me take this point from point number one to point number six.

[00:28:00]All in construction.

[00:28:02]Point number two to point number one.

[00:28:08]Again point number six to point number five.

[00:28:18]Again point number five to point number four.

[00:28:24]Firstly everything you do in construction. Point number three to point number four.

[00:28:32]I'll try by all means to make this feature short.

[00:28:37]Then I can close this.

[00:28:43]Same as this one on this side. I'm going to join it together. Point number one to point number six.

[00:28:53]Point number five to point number.

[00:28:57]Point number six to point number five all together.

[00:29:07]Again point number five to point number four.

[00:29:16]Point number three to point number four.

[00:29:21]Point number two to point number one.

[00:29:29]Then I can join point number three and two here.

[00:29:38]Actually now this is what I have.

[00:29:43]Let me try bring bit close to you.

[00:29:49]So I have joined this together. I have joined this. So I'm going to close this line here and this line here which is that one there also that one there as you can see they all go together. So now we are going to use our circle which is uh on the aux view.

[00:30:26]Now we are going to work towards this circle here.

[00:30:34]So we need to divide this circle into equal spaces.

[00:30:43]Let me try to do it for you. So from here to the center here. Okay.

[00:30:53]The center here.

[00:30:56]Then I'm going to make a arc on my right.

[00:31:00]I'm going to make a ar on my left.

[00:31:06]Then I make a point bullet point here.

[00:31:09]A bullet point here.

[00:31:12]Same as you on top here.

[00:31:19]From here goes to my side. I'm going to make a to my right. We'll make a ar to my left hand side. Then I'm going to make a bread point here.

[00:31:33]Okay. Now I'm going to use this line again.

[00:31:39]From here to the center, I'm going to make a arc here.

[00:31:50]But I'm going to make a arc here on top.

[00:31:53]I'm going to do the same thing on the side from here to my center. Then I make a arc here and make a ar.

[00:32:05]So again, I make a bullet point here.

[00:32:08]bullet point here. Bullet point here, bullet point here, bullet point here, bullet point here. So, I'm going to give these points um some names or you say I'm going to label these bread points.

[00:32:26]Now, I want to use a different uh different pen. Hence, I use the red pen name. I want to use a different one which is um but for you you can you're not allowed to use a different colors here. You can only use your pencil.

[00:32:49]Okay. So I'm going to start from the bottom here which is I'm going to say this is A.

[00:32:58]This is B. I'm going to go um clockwise.

[00:33:04]A B C D E F G H I G K then N.

[00:33:25]So I have this blood point here. a bread point and forget that. So, what I'm going to do now, I'm going to take this bread points, all of them, and I'm going to stop them here.

[00:33:40]I'm going to project all of them into this line here into this one.

[00:33:48]So, yeah, let me do that for you.

[00:33:58]Let me do that for you. So, um, if I can take a note here, this point, this K and C, they go together.

[00:34:08]They go together.

[00:34:11]Point I and E go together. Point H and F go together. Same as point L and B go together. So, point A is already here.

[00:34:25]I can also say this is point A here cuz it's already here.

[00:34:34]Let me go take point B.

[00:34:40]Point B point B and L goes together.

[00:34:44]Goes together. So, um I'm trying to make this room to be neat at the same time.

[00:34:50]But let me do this.

[00:34:54]I know this is point L. Yeah.

[00:35:00]Goes with um sorry point L goes with point B.

[00:35:11]But if ever if I'm going to continue labeling also the side, this going to look a little bit confusing. So let me not label it on the side.

[00:35:22]Then um I know that point K and C goes together.

[00:35:33]Yeah.

[00:35:34]Uh D and J ordered here.

[00:35:44]Jens don't start.

[00:35:52]This one. This one is in.

[00:36:03]Okay, that is point F and H here. G. So, what am I going to do? I'm going to take all these points here. I just constructed them to the side to all them to join here by this con here this point.

[00:36:26]Let me do it for you.

[00:36:31]The spoil line here already is here. I'm taking this one.

[00:36:43]I'm taking also this one here that's between E and I point A and I and then this D and J already here. So I'm going to take point C and K.

[00:37:06]CK point C with point.

[00:37:21]Then again I'm going to take point B and L which is this one here.

[00:37:36]Okay. I tried by all means to use construction lines just to make this a little bit neat and also you don't don't get confused.

[00:37:47]So, uh it's about 37 minutes now. Okay.

[00:37:53]Again, I'm going to project all these angles here, all of them to my top view that I'm trying to do, which is this one. Let me zoom out.

[00:38:16]So, all these lines here going to tear them down.

[00:38:31]that angle there.

[00:38:36]All of them I'm going to draw them.

[00:38:39]Construction.

[00:38:43]Construction. Construction.

[00:38:45]Construction. Construction.

[00:38:57]All of them will go in construction. Yeah.

[00:39:19]constructions all of them. I'm trying by all means to be accurate.

[00:39:29]And the last one which is a Yeah.

[00:39:35]Okay.

[00:39:38]Now I'm going to do the same thing that I I I I did when I was looking for this part these ones. Yeah.

[00:39:47]>> The same thing. So I'm going to say from point A from point A which is here to my X Y line to this one here.

[00:40:08]Then from that line there of A which is here that is my line for point A. I'm going to start point it here.

[00:40:22]Okay. So from here can check if ever this fine.

[00:40:29]Come to me during break time. Come to me during break time.

[00:40:37]That is my distance there at point A. So point A is here again.

[00:40:47]We place that there.

[00:40:50]Then the spool here. Okay. The spool here.

[00:40:58]Again without labeling the things going to get you confused. So let me see this point A here. Point B P point B goes here that distance for B.

[00:41:19]Remember B goes with L.

[00:41:23]So that distance there for B is here.

[00:41:33]on the slide that point is there that is B.

[00:41:42]Okay, let me make it easier and quick.

[00:41:45]So at this point earlier, point L is here again on that line of B which is this one here from here to go slide here. Yeah, that is going to be L the point the L.

[00:42:13]Oh, I can't see it.

[00:42:15]But this one here on the same line of B same line here. Then again from C to my XY line that line for C which is here. This can take a lot of time to do but you need to be very careful when you're doing it.

[00:42:42]that point there which is point for C again C goes uh with K gives you gives you CK CK so that point there stands again it's going to take me a lot of time to to finish I'm doing K now so again that line of C which is going to be that 4K uh which is uh yeah which is here that is okay hopefully now we get it how to do it then this is D here that is D Yeah, that line for D. This one here, the center.

[00:43:46]That line for D.

[00:43:51]This line is for D. Also for J here, that line for J. So d= to j gives you dj.

[00:44:09]So on this point here that is d.

[00:44:15]Oh that is j here on this side. Sorry that is j on this side. Then let me try to quick again that is I.

[00:44:27]I goes with a. So that line there is this point here, this line here, which is this one here.

[00:44:42]That gives me I then let me go to E.

[00:44:51]That is E here.

[00:44:55]That line. Same line here.

[00:45:01]Same line here.

[00:45:03]That is a then H here.

[00:45:15]That is H. Yeah. So that line for H goes with F.

[00:45:23]This one here that is F here. H that is H.

[00:45:38]F is here.

[00:45:43]That is F there.

[00:45:46]which is same line here.

[00:45:53]Uh that line here for that line is for F.

[00:46:06]Uh that line is for F. I'm trying to get this into the full string.

[00:46:17]You can see all of it. Then I'm going to take that point for G.

[00:46:27]Ges.

[00:46:31]Then I'm going to go through that line there, which is all the way down here.

[00:46:44]this line there for G and that is where I get that point here.

[00:46:55]You can see um this giving you already these points here. You can join them together. They're giving you already how that cycle it is.

[00:47:10]So, um let me stop this video uh this uh 47 minutes.

[00:47:18]Then I'm going to do another one to continue from where I stopped.
