I want to load a model and maintain the same unique id whenever loaded. When I unload a model, I remove it and dispose of the mesh geometry and mesh material and call localStorage.clear(). But when I reload the model the unique ids for all the meshes are different. The only way I can get the same id on each load is to also call location.reload(true). But I don't want to reload because in angular the entire application will restart. Any suggestions on how to clear the memory threejs uses in order to get reusable ids? Thanks in advance!
Three.js automatically assigns UUIDs to objects. However, there's no reason why you cannot overwrite this value:
const staticID = "9B60F750-C64F-433A-8C1E-9E88639DC503";
onLoad(object) {
object.uuid = staticID;
}
That way, each time you load your Object3D, it'll have the same "unique" ID as last time.

I’m trying to create a new dataset type Powerapps Component (PCF). For the moment I am using it to display a view of the records that are available in an entity in Microsoft Dynamics CRM.
I wish to make the view sort itself when I click on the grid column headers (in a similar way that the default CRM grid view does). I'm trying to figure out how to apply a sort to the dataset so that I can refresh it as indicated by the documentation for the dataset.refresh() function:
Refreshes the dataset based on filters, sorting, linking, new column.
New data will be pushed to control in another 'updateView' cycle.
The dataset object does have a “sorting” property, but changing its value and then refreshing the dataset doesn’t seem to have any effect. After the refresh, the sorting property reverts to the value it had before I changed it.
In short, the click handler for the grid header does something like the following bit of code. The refresh gets done and my updateView() function gets called as expected but the sorting was not applied.
dataset.sorting = [{name: 'createdon', sortDirection: 1}];
dataset.refresh();
Any help on getting the dataset sorting to work would be appreciated.
I've been experimenting with PowerApps Component Framework a little bit recently and I can confirm that the following code won't be working:
dataSet.sorting = [ { name: "columnName", sortDirection: 0 } ];
However, I managed to get this one working for me:
dataSet.sorting.pop(); // you may want to clean up the whole collection
dataSet.sorting.push({ name: "columnName", sortDirection: 0 });
I haven't really figured out the reason of this behavior. The sorting array may be implemented as some form of observable collection in the background.
I hope this will guide you to a functioning solution.
The documentation is pretty abysmal here, but here is my best guess from putting a few different pieces of information together.
TLDR: I think there is some kind of extra method that needs to be called on the .sorting property, but I can't find out what it is called. Maybe something like:
dataset.sorting.setSorting({name: 'createdon', sortDirection: 1});
I think you're going to have to try a bunch of likely method names and see what works.
Background and links:
The only reference I could find to dataset.sorting was from here:
In this preview for canvas apps, only a limited set of filtering and sortStatus methods are supported. Filter and sort can be applied to dataset on primary type columns except for the GUID. Filter and sorting can be applied in the same way as in model-driven apps.To retrieve the dataset with filtering and sorting information, call
the methods in context.parameters.[dataset_property_name].filtering
and context.parameters.[dataset_property_name].sorting, then invoke
the context.parameters.[dataset_property_name].refresh().
So it seems that the .filtering and .sorting properties are handled similarly, and that there are some methods attached to them, and only some are supported. That is about as vague as they could make it...
I did find an example of how .filtering is used:
_context.parameters.sampleDataset.filtering.setFilter({
conditions: conditionArray,
filterOperator: 1, // Or
});
There is a brief reference to .setFilter() in the docs, as well as FilterExpression
There is a SortStatus reference, but it doesn't have any corresponding methods explicitly called out. It is possible that this is not yet a supported feature in the public preview, or the documentation is lacking and the name and syntax of the method you need to call on .sorting is not yet documented.
I am trying to list the view template’s properties so we can compare them with another old template.
For example what model elements are hidden or have overrides in a given template or which Revit links have been hidden or overridden in a given template.
View Template
(https://www.google.com/search?q=view+template+revit&rlz=1C1GGRV_enUS770US770&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjLndrd2cTbAhVESq0KHX1cAPwQ_AUICygC&biw=1536&bih=824#imgrc=Q0v-pV7Nxl4kfM:)
I’m looking to devise a View Template Compare tool and access to the owner and creator of them.
public void ApplyViewTemplateToActiveView()
{
Document doc = this.ActiveUIDocument.Document;
View viewTemplate = (from v in new FilteredElementCollector(doc)
.OfClass(typeof(View))
.Cast<View>()
where v.IsTemplate == true && v.Name == "MyViewTemplate"
select v)
.First();
using (Transaction t = new Transaction(doc,"Set View Template"))
{
t.Start();
doc.ActiveView.ViewTemplateId = viewTemplate.Id;
t.Commit();
}
}
With Revit API you can access with:
GetTemplateParameterIds Method / ViewTemplateId Property
The Revit API exposes almost all the ViewTemplate properties.
For instance this method returns all the Visibility/Graphic Overrides for a specific category:
https://apidocs.co/apps/revit/2019/ed267b82-56be-6e3b-0c6d-4de7df1ed312.htm
The only thing I couldn't get for a ViewTemplate are the "includes", but all the rest seems to be there.
Update:
The list or properties "not included" can be retrieved with GetNonControlledTemplateParameterIds().
Yes, and no.
Yes, I guess you can use Forge Model Derivative API to export RVT file and then build a dashboard around the View Templates data. That's assuming that View Templates data actually gets exported when the model is translated. That data is not attached to any geometry so I would not be surprised if it was skipped. The question here is why? This is like renting a 16-wheel truck to move a duffel bag across the street.
No, if your intention is to directly interact with the RVT model. Forge can view it, but to push anything back or request changes to the model, is not available yet. Then again, I am not even sure that the view template data is available via model derivative exports.
This brings me another alternative. Why not just collect the data using Revit API, the standard way and then push it out to a Database and build on top of that? There is no reason to employ Forge for any of that.
Thanks Jeremy, I had dig into your amazing website and also some solution that Konrad post in the Dynamo Forum about this. In Revit seems pretty achievable, you filter the View that is View Template and then extracts these properties, is it correct?.
I am wondering if someone can point me in the right direction with Forge.
Some amazing guys are developing a BQL https://www.retriever.works/.
BQL(Building Query Language) is a query language for buildings, similar to how SQL is a query language for databases. It is fast and flexible. BQL helps improve efficiency for QA/QC (quality assurance and quality control), and building data extraction without leaving Revit. I am also trying these and I would like to understand if there are some works where I could start with Forge next week about this.
I'm experiencing an issue refreshing data in XPCollection after commiting some database changes using UnitOfWork.
I have a WinForm with an XPCollection.
The XPCollection uses XpoDefault.Session.
I do some changes through a UnitOfWork:
using (UnitOfWork uow = new UnitOfWork())
{
var photos = new XPCollection<Photo>(uow);
photos[0].Date = DateTime.Now;
uow.CommitTransaction();
}
To get the original XPCollection to update the changes, I've tried the following:
foreach (Photo photo in myXPCollection)
{
XpoDefault.Session.Reload(photo);
}
foreach (Photo photo in myXPCollection)
{
photo.Reload();
}
myXPCollection.Reload()
None of the methods work.The changes are not reflected in the original XPCollection.
They are only visible when I start with a completely new Session. Obviously, this is a big performance problem.
How to get the changes made using UnitOfWork to another Session?
You said:
They are only visible when I start with a completely new Session. Obviously, this is a big performance problem.
That's exactly what you should do. Create a new UnitOfWork each time you want refreshed data. A UnitOfWork is very cheap performance-wise to instantiate. If you have a large collection of Photo objects, you should improve performance by loading only the objects you need by specifying the Criteria parameter in the XPCollection<Photo> constructor.
When you issue Reload() it doesn't fetch anything from the database: it discards any changes and reloads the object from the session identity map. You can read this article and this Support Center issue for more information.
By the way, the DevExpress Support Center is by far the best place to ask DevExpress questions.
What I am trying to do and is failing is this:
worldMap.series.regions[0]=new jvm.DataSeries({
scale:['#CCCCCC','#FF0000'],
normalizeFunction:'polynomial',
values:{'country_code':value...},
min:minValue,
max:maxValue
});
The error I get is that regions is not defined, so I'm doing that wrong.
What is the proper way of doing that and how can I dispose of data if I don't need it anymore (as in remove colouring of countries as if map was initialized with empty dataset).
Thank you.
If all you want to do is to change series data then you can use DataSeries methods like clear and setValues:
worldMap.series.regions[0].clear();
I’m building an MVC3 application with form authentication and a single hierarchical entity. The entity has a Region object as the “root” with several other objects. It looks something like:
Region->Language->objectA->objectB
Region->Application->….
Each user (other than administrators) is associated with single region. I'd like to limit the data loaded to the entity based on the user’s region. I’m not too familiar with EF. Is this appropriate or is there a better approach? How would I implement the best approach
You can certainly filter the data returned via Entity Framework. The code would look something like this:
using (MyContext ctx = new MyContext())
{
var filtered = (from r in ctx.Regions where SOME_CONDITIONS select r);
// Do stuff with filtered (which is an IEnumerable<Region>)
}
Note that you may need to use Include to load related objects, e.g.
ctx.Regions.Include("Language").Include("Application")
