1 00:00:05,910 --> 00:00:11,620 Are right now let's do another little practice modeling here we're going to be seeing how we can model 2 00:00:11,650 --> 00:00:12,700 a gear. 3 00:00:12,760 --> 00:00:15,890 So we're going to be using the array modifier. 4 00:00:15,910 --> 00:00:21,310 We're going to be using another modifier that we haven't taken a look at yet which is called the boolean 5 00:00:21,310 --> 00:00:23,310 modifier which is really cool. 6 00:00:23,440 --> 00:00:29,290 And we're going to be using some little tips and tricks along the way which we're going to learn from 7 00:00:29,470 --> 00:00:34,000 which we can then implement into any project we want. 8 00:00:34,060 --> 00:00:35,520 So let's go right ahead. 9 00:00:35,650 --> 00:00:40,810 And this is how you learn just by doing projects and when you do them you learn something new every 10 00:00:40,810 --> 00:00:46,340 time because for every project you might need a different tool or different way of doing things. 11 00:00:46,360 --> 00:00:53,320 So for a year let's delete our default cube by hitting X and delete hits shift day and we're going to 12 00:00:53,320 --> 00:01:01,400 add a mesh circle going to leave at 32 vertices and that is just fine and dandy. 13 00:01:01,740 --> 00:01:04,590 Now hitting tab to go into edit mode again. 14 00:01:04,620 --> 00:01:07,970 We want to work smart not necessarily hard. 15 00:01:07,980 --> 00:01:16,650 So what we're going to do is duplicate our our gear around four times and just have to model one portion 16 00:01:16,650 --> 00:01:17,260 of it. 17 00:01:17,550 --> 00:01:25,200 So to do that let's go ahead and box select all this by hitting the Beaky left click and dragging. 18 00:01:25,200 --> 00:01:33,810 Same here and hitting X delete vertices minus that vertices. 19 00:01:34,370 --> 00:01:34,730 All right. 20 00:01:34,730 --> 00:01:44,020 Now let's go ahead and go to our modifiers tab click and modifier and let's add an array modifier. 21 00:01:45,060 --> 00:01:50,620 We're going to duplicate it four times and we want it to spin around here. 22 00:01:50,640 --> 00:01:55,320 Now we can see that right now it's not duplicating how we want it to. 23 00:01:55,320 --> 00:02:01,350 So what we need to do is with our cursor still at the origin of our sites or circle go ahead and hit 24 00:02:01,350 --> 00:02:06,940 shift day and we're going to add an empty. 25 00:02:06,980 --> 00:02:09,130 Now going back to our circle. 26 00:02:09,290 --> 00:02:09,920 Go ahead. 27 00:02:09,920 --> 00:02:17,180 And instead of relative offset which is offsetting it on a certain axis go ahead and uncheck that and 28 00:02:17,180 --> 00:02:22,920 we're going to select object offset by go ahead and select the empty. 29 00:02:22,990 --> 00:02:29,650 You can see nothing has happened yet but selecting the empty five selected with right mouse click and 30 00:02:29,650 --> 00:02:31,270 then rotate it. 31 00:02:31,270 --> 00:02:34,840 You can see that's offset via the object. 32 00:02:34,930 --> 00:02:36,590 Pretty awesome. 33 00:02:36,760 --> 00:02:43,430 So what I'm going to do is I'm going to hit r to rotate it and then 90 degrees. 34 00:02:43,460 --> 00:02:50,420 So now this empty is offsetting our array modifier and you could see that. 35 00:02:50,420 --> 00:02:55,100 Now anything we do here will happen on all four. 36 00:02:55,150 --> 00:02:56,730 All three of the other ones. 37 00:02:56,740 --> 00:02:58,540 Pretty cool. 38 00:02:58,540 --> 00:03:01,480 All right so now what we want do is bring out our years. 39 00:03:01,510 --> 00:03:08,540 So hitting control tab going to edge select mode I'm going to go ahead and select this edge right here. 40 00:03:09,380 --> 00:03:10,570 This one right here. 41 00:03:10,940 --> 00:03:15,800 This one and this one so every other edge we are going to select. 42 00:03:15,990 --> 00:03:21,730 Now making sure our cursor is at the bottom or still in the center. 43 00:03:21,840 --> 00:03:31,350 And if it isn't just hit shift us cursor to selected and we want to hit you to extrude right click to 44 00:03:31,350 --> 00:03:33,950 leave it and then scale it out. 45 00:03:34,170 --> 00:03:37,240 Except right now it's scaling in a weird way. 46 00:03:37,440 --> 00:03:44,820 So let's go ahead and move our scale in position from a median point to 3D cursor because right now 47 00:03:44,820 --> 00:03:46,440 it's scaling around here. 48 00:03:47,300 --> 00:03:53,530 But if we go to a 3-D cursor you can see that if we scale it it will scale along the 3D cursor. 49 00:03:53,570 --> 00:03:54,520 Pretty cool. 50 00:03:55,760 --> 00:03:56,320 All right. 51 00:03:56,390 --> 00:04:03,140 Now what we want to do is scale these down or scale them and so that they're thinner at the top. 52 00:04:03,260 --> 00:04:08,170 The way we can do that is go in here individually and scale them down. 53 00:04:08,360 --> 00:04:09,650 But that might take a while. 54 00:04:09,650 --> 00:04:15,960 So what we're going to do is go over here go to individual origins. 55 00:04:15,980 --> 00:04:25,890 So median point is basically if I select all of these go to median point and I try to scale these along 56 00:04:26,010 --> 00:04:29,980 their axes or along the top right here so what I want to do. 57 00:04:30,240 --> 00:04:39,480 And if we change this from global to normal we can now scale along the y axis so s y once and then Y 58 00:04:39,510 --> 00:04:42,020 once again to scale along its normal. 59 00:04:42,390 --> 00:04:47,570 But I don't want to go individually one on one to do each and every single one of these. 60 00:04:47,610 --> 00:04:54,370 So if I select all of them you can see that right now it's set to median points so averages out all 61 00:04:54,370 --> 00:04:55,320 four of them. 62 00:04:55,440 --> 00:05:03,510 And I can no longer scale them individually but if I go over here and select individual Origin's you 63 00:05:03,510 --> 00:05:12,950 can see that now if I hit as Y and then hit Y once again it's actually scaling them along each of their 64 00:05:13,070 --> 00:05:14,130 origins. 65 00:05:14,390 --> 00:05:15,810 Pretty cool. 66 00:05:15,830 --> 00:05:20,780 So let's go ahead and do that and you can see that every single one of them has a different line and 67 00:05:20,780 --> 00:05:24,510 a different normal which is scaling along their. 68 00:05:24,690 --> 00:05:26,200 All right so let's bring that out. 69 00:05:26,230 --> 00:05:31,880 Let's bring this back to median point and let's leave it at that. 70 00:05:31,900 --> 00:05:34,790 And let's also bring it back to global. 71 00:05:34,800 --> 00:05:35,210 All right. 72 00:05:35,230 --> 00:05:35,780 Awesome. 73 00:05:35,780 --> 00:05:43,720 Now let's all right click alt shift click all these edges. 74 00:05:44,900 --> 00:05:46,690 Hitting e to extrude. 75 00:05:46,860 --> 00:05:53,090 Let's then scale it down towards the cursor so if we hit s it's not scaling properly. 76 00:05:53,180 --> 00:06:00,920 When you actually move this back to 3D cursor and now when we scale it it will scale it down towards 77 00:06:00,920 --> 00:06:02,900 the 3D cursor. 78 00:06:02,900 --> 00:06:03,410 Awesome. 79 00:06:03,410 --> 00:06:07,630 Now you can see we have some kind of strange artifact going on. 80 00:06:07,730 --> 00:06:16,600 And if we hit a to select our entire mesh and then control and it will do what's called recalculating 81 00:06:16,600 --> 00:06:23,710 the normals because the problem is some of the faces there are normal's were flipped the other way. 82 00:06:23,710 --> 00:06:29,430 Not the actual object itself but the normal meaning the way that it was facing. 83 00:06:29,920 --> 00:06:36,340 So basically flipping the normal's recalculates all of them and make sure that they are facing the right 84 00:06:36,340 --> 00:06:39,870 way or that the normals are facing the right way. 85 00:06:39,940 --> 00:06:48,620 You can see right here if I hit control-C to undo if I go to a normal and select a face here control 86 00:06:48,620 --> 00:06:56,830 tab face and I go to the median point you can see that right now the normal of that face is going down 87 00:06:56,840 --> 00:07:00,740 the Z-axis Whereas on this one it's going up. 88 00:07:00,740 --> 00:07:01,850 This one's going down. 89 00:07:01,850 --> 00:07:02,900 This one's going up. 90 00:07:02,900 --> 00:07:04,340 This one's going down. 91 00:07:04,340 --> 00:07:11,380 And so that's what the normals are the normals are facing in opposite directions on every single one 92 00:07:11,380 --> 00:07:11,620 of them. 93 00:07:11,620 --> 00:07:17,570 So when we hit a to select all of them and then control an recalculates the normals. 94 00:07:17,590 --> 00:07:19,970 So they're all facing the same way. 95 00:07:20,780 --> 00:07:26,450 And basically the the weird artifact we have is because the light is bouncing differently on every single 96 00:07:26,450 --> 00:07:30,580 one of them because the normals are facing the wrong way. 97 00:07:30,620 --> 00:07:31,000 All right. 98 00:07:31,040 --> 00:07:31,460 Awesome. 99 00:07:31,460 --> 00:07:37,880 So that is the start of our gear and we are heading in a good direction. 100 00:07:40,250 --> 00:07:46,250 All right ladies and gentlemen if you want to find me after I'll be snowboarding down the mountain. 101 00:07:46,810 --> 00:07:53,560 OK our quote for today or this video is Don't believe everything that you think sometimes we can buy 102 00:07:53,560 --> 00:08:00,520 into the illusion that it is us but in reality it's usually a belief that we took on from a long time 103 00:08:00,520 --> 00:08:06,680 ago that has no more validity but yet we are still running with that same old program. 104 00:08:06,710 --> 00:08:12,500 It's hard to update yourself to you oh and see how much your life changes. 105 00:08:12,500 --> 00:08:14,070 Remember you're never stopped. 106 00:08:14,110 --> 00:08:15,430 You can always change. 107 00:08:15,430 --> 00:08:17,440 I'll see you in the next video. 108 00:08:17,470 --> 00:08:18,330 Oh boy.
