1 00:00:00,005 --> 00:00:02,003 - [Instructor] Okay, now we can get into it. 2 00:00:02,003 --> 00:00:04,000 The first family I'm always asked to make 3 00:00:04,000 --> 00:00:05,004 is that little triangular shape 4 00:00:05,004 --> 00:00:07,002 that is basically a blob of concrete, 5 00:00:07,002 --> 00:00:10,006 cast against the earth in a step footing situation. 6 00:00:10,006 --> 00:00:12,006 Especially this little chunk right here. 7 00:00:12,006 --> 00:00:13,006 But you see what we're going to do, 8 00:00:13,006 --> 00:00:17,000 if we select this little chunk of concrete, 9 00:00:17,000 --> 00:00:21,005 notice that that's independent from the entire footing. 10 00:00:21,005 --> 00:00:23,005 If I click Edit Type, 11 00:00:23,005 --> 00:00:25,009 notice that I've got all these parameters in here 12 00:00:25,009 --> 00:00:28,009 that we're about to make. 13 00:00:28,009 --> 00:00:30,007 This is the safest way to do a family. 14 00:00:30,007 --> 00:00:31,009 So we're going to make a family. 15 00:00:31,009 --> 00:00:33,008 We're going to load it into the project 16 00:00:33,008 --> 00:00:36,008 and we're going to combine it with our wall steps. 17 00:00:36,008 --> 00:00:38,007 Okay, so, to get started under families, 18 00:00:38,007 --> 00:00:43,000 let's go New. 19 00:00:43,000 --> 00:00:47,008 I'm going to go to English Imperial. 20 00:00:47,008 --> 00:00:48,006 And I'm going to make sure 21 00:00:48,006 --> 00:00:54,005 that I'm using a structural foundation family template. 22 00:00:54,005 --> 00:01:00,009 Structural foundation, click Open. 23 00:01:00,009 --> 00:01:02,008 Great, now the first thing we're going to do 24 00:01:02,008 --> 00:01:03,006 is make sure we set it 25 00:01:03,006 --> 00:01:08,003 for work plane-based, excellent. 26 00:01:08,003 --> 00:01:12,002 Also notice that if we go to our family types, 27 00:01:12,002 --> 00:01:15,005 we already have some dimensions built in. 28 00:01:15,005 --> 00:01:17,006 If I close out of here, 29 00:01:17,006 --> 00:01:21,000 let's go to our family category and parameters. 30 00:01:21,000 --> 00:01:24,008 Notice that it's allocated as structural foundations. 31 00:01:24,008 --> 00:01:27,000 Ramps want to make a schedule and all that stuff 32 00:01:27,000 --> 00:01:31,001 it's going to show up, hit OK. 33 00:01:31,001 --> 00:01:32,009 Now right click on this reference plane 34 00:01:32,009 --> 00:01:35,006 and create similar. 35 00:01:35,006 --> 00:01:39,008 On the draw panel, click Pick Lines. 36 00:01:39,008 --> 00:01:43,001 For the offset, let's go two feet. 37 00:01:43,001 --> 00:01:48,000 So offset this to the left and to the right. 38 00:01:48,000 --> 00:01:52,007 Now for an offset, let's go one foot. 39 00:01:52,007 --> 00:01:54,007 I'll set this up. 40 00:01:54,007 --> 00:01:57,004 I'll set this down. 41 00:01:57,004 --> 00:01:59,004 Hit Escape a couple of times. 42 00:01:59,004 --> 00:02:00,006 Now let's dimension them up. 43 00:02:00,006 --> 00:02:04,001 Click Aligned Dimension on the measure panel, 44 00:02:04,001 --> 00:02:08,004 I'm going to go from here to here, to here, to here. 45 00:02:08,004 --> 00:02:15,005 I'm going to click EQ and I'm going to go from here to here. 46 00:02:15,005 --> 00:02:17,008 Now, select your forefoot dimension. 47 00:02:17,008 --> 00:02:19,005 And we have a label already for us. 48 00:02:19,005 --> 00:02:22,001 Let's call it length. 49 00:02:22,001 --> 00:02:24,007 Hit Escape a few times. 50 00:02:24,007 --> 00:02:28,009 In the measure panel, click Aligned Dimension. 51 00:02:28,009 --> 00:02:32,004 Go from here to here, to here, up to here. 52 00:02:32,004 --> 00:02:37,000 Click EQ, go from here to here, click off of it 53 00:02:37,000 --> 00:02:41,003 and hit Escape a few times, select the two foot dimension. 54 00:02:41,003 --> 00:02:46,004 For the label I'd like to call that Foundation Thickness. 55 00:02:46,004 --> 00:02:50,004 Hit Escape a few times, excellent. 56 00:02:50,004 --> 00:02:54,008 Let's go to our front elevation. 57 00:02:54,008 --> 00:02:58,009 Right click on this reference plane and create similar. 58 00:02:58,009 --> 00:03:03,003 On the draw panel, click on Pick Lines. 59 00:03:03,003 --> 00:03:08,003 Now let's offset up our ref level, two feet. 60 00:03:08,003 --> 00:03:10,001 Hit Escape a few times. 61 00:03:10,001 --> 00:03:13,001 On the measure panel, click Align Dimension, 62 00:03:13,001 --> 00:03:16,008 dimension from our ref level to our top. 63 00:03:16,008 --> 00:03:17,009 Pick a point. 64 00:03:17,009 --> 00:03:19,000 It's like the two foot dimension. 65 00:03:19,000 --> 00:03:21,001 Now we're going to have to start making our own parameters. 66 00:03:21,001 --> 00:03:25,009 So click on Create Parameter. 67 00:03:25,009 --> 00:03:30,009 Call that height, hit OK. 68 00:03:30,009 --> 00:03:32,009 Hit Escape a couple of times. 69 00:03:32,009 --> 00:03:33,008 Let's make one more. 70 00:03:33,008 --> 00:03:37,008 Right click on this reference plane here, create similar. 71 00:03:37,008 --> 00:03:41,005 On the draw panel, click Pick Lines. 72 00:03:41,005 --> 00:03:43,002 Let's go one foot. 73 00:03:43,002 --> 00:03:46,009 I'll set this to the left, one foot. 74 00:03:46,009 --> 00:03:47,008 Let's dimension that, 75 00:03:47,008 --> 00:03:53,000 remember from our strong reference to our weak reference. 76 00:03:53,000 --> 00:03:56,001 Select the one foot dimension. 77 00:03:56,001 --> 00:03:58,005 Click your Create Parameter button. 78 00:03:58,005 --> 00:04:03,003 Let's call that heal Depth. 79 00:04:03,003 --> 00:04:05,008 Click OK. 80 00:04:05,008 --> 00:04:08,003 All right, it's extrusion time. 81 00:04:08,003 --> 00:04:09,009 Go to Create. 82 00:04:09,009 --> 00:04:12,007 Go to Extrusion. 83 00:04:12,007 --> 00:04:14,007 Now they want to reference work plane. 84 00:04:14,007 --> 00:04:15,005 So that's okay. 85 00:04:15,005 --> 00:04:17,006 Click the drop down, we'll go center front-back 86 00:04:17,006 --> 00:04:19,004 is known as for in the front elevation. 87 00:04:19,004 --> 00:04:20,006 So center front-back. 88 00:04:20,006 --> 00:04:22,003 We'll have to fix that in plane. 89 00:04:22,003 --> 00:04:24,003 Click OK. 90 00:04:24,003 --> 00:04:25,002 On the draw panel, 91 00:04:25,002 --> 00:04:29,002 make sure that your draw line is selected. 92 00:04:29,002 --> 00:04:34,000 I'm going to go from here to here, 93 00:04:34,000 --> 00:04:37,001 to here, to here, 94 00:04:37,001 --> 00:04:38,005 down to here. 95 00:04:38,005 --> 00:04:40,004 Hit Escape a couple of times. 96 00:04:40,004 --> 00:04:42,009 Now, before we forget, our material wants 97 00:04:42,009 --> 00:04:45,003 to be set to something, but we're not sure what. 98 00:04:45,003 --> 00:04:50,004 So go ahead and just click on Associate Family Parameter. 99 00:04:50,004 --> 00:04:54,001 Grab structural material, click OK. 100 00:04:54,001 --> 00:04:57,001 Now click finish. 101 00:04:57,001 --> 00:04:59,009 Now let's go down to our ref level floor plane. 102 00:04:59,009 --> 00:05:01,004 We just need to align it. 103 00:05:01,004 --> 00:05:04,006 Type AL for align. 104 00:05:04,006 --> 00:05:07,006 Select your top reference plane. 105 00:05:07,006 --> 00:05:11,006 Select your extrusion shape handle, click on lock. 106 00:05:11,006 --> 00:05:14,004 Now let's grab the bottom one. 107 00:05:14,004 --> 00:05:16,009 Let's grab the bottom extrusion shape handle 108 00:05:16,009 --> 00:05:21,008 and lock that just to be sure it's going to work. 109 00:05:21,008 --> 00:05:24,008 Go to a 3D view. 110 00:05:24,008 --> 00:05:26,009 Not looking too bad. 111 00:05:26,009 --> 00:05:27,007 Let's save it. 112 00:05:27,007 --> 00:05:33,009 Let's go File, Save As, Family. 113 00:05:33,009 --> 00:05:35,007 Browse where you are keeping your exercise files. 114 00:05:35,007 --> 00:05:38,004 I'm going to save mine as Stepped Footing. 115 00:05:38,004 --> 00:05:41,009 For my options, I'll just make sure I have one backup. 116 00:05:41,009 --> 00:05:43,008 Click OK. 117 00:05:43,008 --> 00:05:47,006 Click Save. 118 00:05:47,006 --> 00:05:48,005 There we go. 119 00:05:48,005 --> 00:05:49,009 Now we're ready to bring this stepped footing 120 00:05:49,009 --> 00:05:51,005 into an actual project.
