00:00:00,000 --> 00:00:06,000
|
|
So as you probably saw, IFC comes with a lot of standard property sets that you can use.
|
|
|
|
2
|
|
00:00:06,000 --> 00:00:11,000
|
|
And each property set has a bunch of properties underneath it.
|
|
|
|
3
|
|
00:00:11,000 --> 00:00:17,000
|
|
But sometimes you'll get to a point where you need a certain property that's not in the standard list.
|
|
|
|
4
|
|
00:00:17,000 --> 00:00:20,000
|
|
And you can ultimately create your own if you'd like.
|
|
|
|
5
|
|
00:00:20,000 --> 00:00:28,000
|
|
And to do that, it's under the Project tab here and go down to Property Set Templates.
|
|
|
|
6
|
|
00:00:29,000 --> 00:00:38,000
|
|
So to create a new one then, you click on this plus button here.
|
|
|
|
7
|
|
00:00:38,000 --> 00:00:49,000
|
|
And we're going to call this one OD Property Template.
|
|
|
|
8
|
|
00:00:49,000 --> 00:00:52,000
|
|
And say OK.
|
|
|
|
9
|
|
00:00:52,000 --> 00:00:57,000
|
|
So we're going to name then the property set.
|
|
|
|
10
|
|
00:00:57,000 --> 00:01:01,000
|
|
And for this we're going to do just OD Generic.
|
|
|
|
11
|
|
00:01:01,000 --> 00:01:05,000
|
|
And description, you can add description if you want. I'm not going to do that.
|
|
|
|
12
|
|
00:01:05,000 --> 00:01:20,000
|
|
So this template type then tells you how this particular property set applies to either the instance of an object or the type of an object.
|
|
|
|
13
|
|
00:01:20,000 --> 00:01:29,000
|
|
So if we do this IFC object then, the properties will only apply to the instance and not the type.
|
|
|
|
14
|
|
00:01:29,000 --> 00:01:36,000
|
|
If we do this Pset IFC Type Object, it means they will only apply to the type.
|
|
|
|
15
|
|
00:01:36,000 --> 00:01:43,000
|
|
But if we do this IFC Type Object Override, it applies both to the instance and the type.
|
|
|
|
16
|
|
00:01:43,000 --> 00:01:52,000
|
|
So if you assign a property at the instance level, then it will override whatever is applied at the type level.
|
|
|
|
17
|
|
00:01:52,000 --> 00:01:56,000
|
|
So for this particular example, that's the one I'm going to use.
|
|
|
|
18
|
|
00:01:56,000 --> 00:02:01,000
|
|
I won't cover these other ones. They apply to quantity sets.
|
|
|
|
19
|
|
00:02:01,000 --> 00:02:11,000
|
|
The applicable entity kind of infers what class that this property set will apply to.
|
|
|
|
20
|
|
00:02:11,000 --> 00:02:17,000
|
|
So you could put just IFC Wall in there if you wanted to and just have it specific to that.
|
|
|
|
21
|
|
00:02:17,000 --> 00:02:24,000
|
|
But I'm going to use this to fall here where it's going to apply to all the types and all the instances.
|
|
|
|
22
|
|
00:02:24,000 --> 00:02:27,000
|
|
Basically in the entire schema.
|
|
|
|
23
|
|
00:02:27,000 --> 00:02:31,000
|
|
So it creates kind of a starter property here.
|
|
|
|
24
|
|
00:02:31,000 --> 00:02:36,000
|
|
And if I edit that, you can name the property.
|
|
|
|
25
|
|
00:02:36,000 --> 00:02:43,000
|
|
I'm just going to do comments instance.
|
|
|
|
26
|
|
00:02:43,000 --> 00:02:49,000
|
|
And then the second field is the description. I'm just going to keep that blank.
|
|
|
|
27
|
|
00:02:49,000 --> 00:02:55,000
|
|
So this next one then is the kind of primary measure type.
|
|
|
|
28
|
|
00:02:55,000 --> 00:03:00,000
|
|
And I'll open it here. You can see all the available options.
|
|
|
|
29
|
|
00:03:00,000 --> 00:03:07,000
|
|
You can measure for mass or power ratio or any number of measurements.
|
|
|
|
30
|
|
00:03:07,000 --> 00:03:13,000
|
|
But for this example, I'm just going to do a simple IFC text.
|
|
|
|
31
|
|
00:03:13,000 --> 00:03:18,000
|
|
And then under here, we're just going to do a single value.
|
|
|
|
32
|
|
00:03:18,000 --> 00:03:38,000
|
|
But know that you can have a numerated list of preset values or bounded where maybe a temperature is going to be between five degrees or thirty five degrees or structural loading maybe.
|
|
|
|
33
|
|
00:03:38,000 --> 00:03:46,000
|
|
So I won't get into the rest of these, but know that there's just other ways to formulate your data.
|
|
|
|
34
|
|
00:03:46,000 --> 00:03:50,000
|
|
So we'll say OK there.
|
|
|
|
35
|
|
00:03:50,000 --> 00:03:57,000
|
|
So to figure out where this was saved.
|
|
|
|
36
|
|
00:03:57,000 --> 00:04:02,000
|
|
So you can use it later as you click on that folder there.
|
|
|
|
37
|
|
00:04:02,000 --> 00:04:10,000
|
|
And you can see that it's located at this path right there.
|
|
|
|
38
|
|
00:04:10,000 --> 00:04:22,000
|
|
So every time you start a Bonsai session or start Blender, it will look in this folder for this pset here or whatever number of psets you have.
|
|
|
|
39
|
|
00:04:22,000 --> 00:04:29,000
|
|
And they will be made available to the project that you're working on currently.
|
|
|
|
40
|
|
00:04:29,000 --> 00:04:39,000
|
|
But if you're working with multiple people, you then have to share this file with them to place in their corresponding location.
|
|
|
|
41
|
|
00:04:39,000 --> 00:04:47,000
|
|
The one approach I like to do is actually put this pset in the project folder itself.
|
|
|
|
42
|
|
00:04:47,000 --> 00:04:55,000
|
|
And so when you sync the entire repo, that pset is made available to that person.
|
|
|
|
43
|
|
00:04:55,000 --> 00:05:00,000
|
|
So I'm going to cut this or copy it.
|
|
|
|
44
|
|
00:05:00,000 --> 00:05:03,000
|
|
And I'm going to place it in the project folder.
|
|
|
|
45
|
|
00:05:04,000 --> 00:05:11,000
|
|
And we're going to create a new folder called psets.
|
|
|
|
46
|
|
00:05:21,000 --> 00:05:24,000
|
|
And we're going to paste it in there.
|
|
|
|
47
|
|
00:05:24,000 --> 00:05:29,000
|
|
So we removed it from here and then we added it here.
|
|
|
|
48
|
|
00:05:29,000 --> 00:05:35,000
|
|
So if you then open this file anew,
|
|
|
|
49
|
|
00:05:40,000 --> 00:05:46,000
|
|
and go down to your project templates here, it should be listed here.
|
|
|
|
50
|
|
00:05:51,000 --> 00:05:53,000
|
|
Listed here.
|
|
|
|
51
|
|
00:06:00,000 --> 00:06:12,000
|
|
What we found with using these custom psets is that they are useful enough to be used across projects, not just specific projects.
|
|
|
|
52
|
|
00:06:12,000 --> 00:06:20,000
|
|
So what we like to do is create a Git submodule with our psets that we use a lot,
|
|
|
|
53
|
|
00:06:20,000 --> 00:06:26,000
|
|
and sync them into our individual project repros so that they're available to the actual project.
|
|
|
|
54
|
|
00:06:26,000 --> 00:06:38,000
|
|
So similar to how we created that OD texture repo, and we pulled it into the project, we do that same thing with psets.
|
|
|
|
55
|
|
00:06:38,000 --> 00:06:50,000
|
|
And so we've created a pset repo here with some of the property sets that we find useful for our projects.
|
|
|
|
56
|
|
00:06:50,000 --> 00:07:00,000
|
|
So let's actually just sync this repo as a Git module into our project folder.
|
|
|
|
57
|
|
00:07:00,000 --> 00:07:08,000
|
|
So as kind of a recap, we did this with OD textures, but as a recap, copy that path there,
|
|
|
|
58
|
|
00:07:08,000 --> 00:07:11,000
|
|
and then go to your Git client.
|
|
|
|
59
|
|
00:07:11,000 --> 00:07:17,000
|
|
And we are going to add a new submodule.
|
|
|
|
60
|
|
00:07:18,000 --> 00:07:30,000
|
|
Paste the path there, and the directory we want, we want that directory, but before we actually do that,
|
|
|
|
61
|
|
00:07:30,000 --> 00:07:43,000
|
|
let's go back to our folder here, and we're going to just delete this that we just created.
|
|
|
|
62
|
|
00:07:44,000 --> 00:07:51,000
|
|
And so now we're going to create the submodule.
|
|
|
|
63
|
|
00:07:54,000 --> 00:08:02,000
|
|
So it automatically stages in the pset submodule there, and then we'll just write a little commit message,
|
|
|
|
64
|
|
00:08:02,000 --> 00:08:09,000
|
|
added psets, Git submodule, and so we can commit that locally.
|
|
|
|
65
|
|
00:08:10,000 --> 00:08:21,000
|
|
So now if we go back to Bonsai and reload the file, and go to property templates here,
|
|
|
|
66
|
|
00:08:21,000 --> 00:08:35,000
|
|
and switch this to property template, so you'll see there's a number of psets that we've created in the past.
|
|
|
|
67
|
|
00:08:35,000 --> 00:08:43,000
|
|
And here you can see the comments instance is the one property that we created just a few minutes ago.
|
|
|
|
68
|
|
00:08:43,000 --> 00:08:47,000
|
|
And there's some other ones that we find useful as well.
|
|
|
|
69
|
|
00:08:47,000 --> 00:08:56,000
|
|
So we then can apply that property to the space, one of these spaces, just to test it out.
|
|
|
|
70
|
|
00:08:56,000 --> 00:09:09,000
|
|
Select the space, select all the same class, and then isolate it, and let's pick that primary bedroom again.
|
|
|
|
71
|
|
00:09:10,000 --> 00:09:24,000
|
|
Then go to the objects property, and we are going to add the OD generic pset, generic pset.
|
|
|
|
72
|
|
00:09:30,000 --> 00:09:35,000
|
|
And say testing, instant comment testing, ok.
|
|
|
|
73
|
|
00:09:36,000 --> 00:09:46,000
|
|
So then we can go back to our room finish schedule that we did the last video, and load that.
|
|
|
|
74
|
|
00:09:46,000 --> 00:10:05,000
|
|
We can add another field here, where's the OD generic pset, and then the comments instance there, the property.
|
|
|
|
75
|
|
00:10:05,000 --> 00:10:24,000
|
|
And just say, oops, comments, and we'll open it with the web there, and hopefully it adds that comment to the table.
|
|
|
|
76
|
|
00:10:24,000 --> 00:10:27,000
|
|
So there, it added it right there.
|
|
|
