elements needed 3 00:00:04.07 --> 00:00:06.09 to run a generative design study 4 00:00:06.09 --> 00:00:09.00 including the inputs, generators, 5 00:00:09.00 --> 00:00:11.00 evaluators, and outputs. 6 00:00:11.00 --> 00:00:12.01 So, now let's take a look 7 00:00:12.01 --> 00:00:14.05 at how we can export the Dynamo script, 8 00:00:14.05 --> 00:00:17.02 so that anyone can use it within Revit. 9 00:00:17.02 --> 00:00:18.00 I currently have 10 00:00:18.00 --> 00:00:21.05 the Dynamo and Revit exercise files open for this lesson, 11 00:00:21.05 --> 00:00:24.03 which is where we left off from in the last lesson. 12 00:00:24.03 --> 00:00:26.05 Lucky for us, the Dynamo team 13 00:00:26.05 --> 00:00:28.02 have made it super easy 14 00:00:28.02 --> 00:00:31.07 to deploy our generative design scripts to Revit. 15 00:00:31.07 --> 00:00:33.03 In the menus along the top, 16 00:00:33.03 --> 00:00:36.04 we have a Generative Design tab. 17 00:00:36.04 --> 00:00:38.05 Within this menu is a few functions 18 00:00:38.05 --> 00:00:41.00 that relate to generative design. 19 00:00:41.00 --> 00:00:45.06 The, Create Study and Explore Outcomes selections, 20 00:00:45.06 --> 00:00:48.05 open up the dialogues as they would in Revit. 21 00:00:48.05 --> 00:00:51.00 For example, we can create a study 22 00:00:51.00 --> 00:00:54.03 and this opens up the Create Study option. 23 00:00:54.03 --> 00:00:55.02 Keep in mind here 24 00:00:55.02 --> 00:00:59.02 that we cannot select Revit elements using this method. 25 00:00:59.02 --> 00:01:00.02 So to do this, 26 00:01:00.02 --> 00:01:02.04 we would need to retrieve the wall elements 27 00:01:02.04 --> 00:01:06.01 using traditional Dynamo nodes. 28 00:01:06.01 --> 00:01:08.06 For example, in the workspace, you can see, 29 00:01:08.06 --> 00:01:12.02 we can't select either the room, or the family instance. 30 00:01:12.02 --> 00:01:13.05 Another difference here 31 00:01:13.05 --> 00:01:17.00 is that there is no Create Revit Elements. 32 00:01:17.00 --> 00:01:19.00 So after we've generated our options, 33 00:01:19.00 --> 00:01:22.05 we don't have the option to create the Revit elements. 34 00:01:22.05 --> 00:01:24.09 To do that, we would have to manually set 35 00:01:24.09 --> 00:01:27.09 the data dot gate node, and run the graph 36 00:01:27.09 --> 00:01:31.04 after we have found the inputs that we want. 37 00:01:31.04 --> 00:01:33.00 In Dynamo, we also have the option 38 00:01:33.00 --> 00:01:37.08 to explore outcomes, much like we would in Revit. 39 00:01:37.08 --> 00:01:38.06 You'll notice here 40 00:01:38.06 --> 00:01:44.02 we don't have the option to create those elements. 41 00:01:44.02 --> 00:01:48.04 Now let's focus on the Export for Generative Design option. 42 00:01:48.04 --> 00:01:50.06 This lets us package up our script 43 00:01:50.06 --> 00:01:54.00 to run in Revit without Dynamo. 44 00:01:54.00 --> 00:01:55.07 Before we do that, however, 45 00:01:55.07 --> 00:01:58.00 let's make a saved copy of this script 46 00:01:58.00 --> 00:01:59.03 with a new file name, 47 00:01:59.03 --> 00:02:03.00 as this is what will show up in Revit as the study name. 48 00:02:03.00 --> 00:02:07.00 So let's go to File, Save As. 49 00:02:07.00 --> 00:02:08.09 You can save this wherever you like, 50 00:02:08.09 --> 00:02:10.09 as Revit will take a copy of it 51 00:02:10.09 --> 00:02:13.07 and save it in a folder that it needs to. 52 00:02:13.07 --> 00:02:19.02 I'm going to call mine, Window Placement, and then save it. 53 00:02:19.02 --> 00:02:23.04 Now let's start the export process. 54 00:02:23.04 --> 00:02:26.02 If you have not run your graph since opening this up, 55 00:02:26.02 --> 00:02:28.08 you'll be prompted with this first. 56 00:02:28.08 --> 00:02:30.07 Essentially, we need to run our graph 57 00:02:30.07 --> 00:02:32.08 to ensure that there are no errors. 58 00:02:32.08 --> 00:02:36.00 And because we shouldn't have any if we hit Run, 59 00:02:36.00 --> 00:02:38.07 we get the message that the validation is complete 60 00:02:38.07 --> 00:02:40.06 and it's ready to export. 61 00:02:40.06 --> 00:02:43.02 If there were errors, we would know about it. 62 00:02:43.02 --> 00:02:50.01 For example, if we change the Python script to, Is Output, 63 00:02:50.01 --> 00:02:53.02 we get an error, as the node is not outputting 64 00:02:53.02 --> 00:02:55.06 a valid data type for the outputs. 65 00:02:55.06 --> 00:02:58.03 So let's change that back. 66 00:02:58.03 --> 00:02:59.09 Next, we need a description, 67 00:02:59.09 --> 00:03:03.02 which describes what the graph does to the user. 68 00:03:03.02 --> 00:03:05.04 You want this to be short and concise, 69 00:03:05.04 --> 00:03:08.07 to quickly give the user an understanding of its purpose. 70 00:03:08.07 --> 00:03:12.04 For our study, let's put in, 71 00:03:12.04 --> 00:03:19.02 Maximize Placement of Windows Along Wall, easy. 72 00:03:19.02 --> 00:03:20.07 Next, we need an image, 73 00:03:20.07 --> 00:03:24.08 something that shows the output the graph might provide. 74 00:03:24.08 --> 00:03:26.07 For this, let's simply take a snap 75 00:03:26.07 --> 00:03:29.02 of our current graph background. 76 00:03:29.02 --> 00:03:33.01 To do that, let's minimize this export window. 77 00:03:33.01 --> 00:03:35.06 And then in Dynamo, let's select this button 78 00:03:35.06 --> 00:03:39.01 to switch to background mode. 79 00:03:39.01 --> 00:03:42.02 Before we do that, I'm just going to move or pan over 80 00:03:42.02 --> 00:03:45.03 so that there's no nodes in the view. 81 00:03:45.03 --> 00:03:47.09 Then I'm going to use the Windows Snipping Tool 82 00:03:47.09 --> 00:03:49.08 to take an image of this. 83 00:03:49.08 --> 00:03:58.08 So, want to make sure it's on rectangular, and take a snap. 84 00:03:58.08 --> 00:04:01.04 If you don't have this tool or something similar, 85 00:04:01.04 --> 00:04:03.08 I've copied the image into the exercise folder 86 00:04:03.08 --> 00:04:06.06 for you to use. 87 00:04:06.06 --> 00:04:12.05 So I'm going to save that for now to the desktop. 88 00:04:12.05 --> 00:04:14.05 And then in our Export Window, 89 00:04:14.05 --> 00:04:18.00 let's browse for the image and select it. 90 00:04:18.00 --> 00:04:21.06 Lastly, we have the option to keep the data cached 91 00:04:21.06 --> 00:04:24.07 in the remember nodes, or clear them on export. 92 00:04:24.07 --> 00:04:26.05 If we keep the cached data, 93 00:04:26.05 --> 00:04:29.03 this basically means that the data currently stored, 94 00:04:29.03 --> 00:04:32.01 such as the wall information, will be remembered, 95 00:04:32.01 --> 00:04:35.03 and the user won't need to select a wall element. 96 00:04:35.03 --> 00:04:37.07 As we want the user to start fresh 97 00:04:37.07 --> 00:04:39.05 with any wall element they like, 98 00:04:39.05 --> 00:04:42.01 let's set this to Clear. 99 00:04:42.01 --> 00:04:44.05 Now, all we have to do is export 100 00:04:44.05 --> 00:04:47.01 by hitting this Export button. 101 00:04:47.01 --> 00:04:49.07 As you can see, it's quite fast. 102 00:04:49.07 --> 00:04:51.04 And you'll notice our script 103 00:04:51.04 --> 00:04:54.08 has been copied over to this folder. 104 00:04:54.08 --> 00:04:57.07 So this means each time we update our graph, 105 00:04:57.07 --> 00:04:59.07 we'll have to re-export it 106 00:04:59.07 --> 00:05:01.03 to update the study in Revit. 8404
