Plugin create set by item

[julia_morseP8AHB]

create a plugin that, based on the selection of a item, creates a set with a predefined range of 50cm, for example, for x, y and z. Is it possible?

Hi @julia_morseP8AHB ,

The issue you’re describing is a bit unclear to me.

It is possible to create a SelectionSet in Navisworks via the API.
But I’m not sure what you mean by “creates a set with a predefined range of 50cm, for example, for x, y, and z.”
Could you please provide more details?

[julia_morseP8AHB]

Hi @naveen.kumar.t , yes.

For example, after selecting a piece of equipment, it would create a "volume" of size X that would encompass items around the element.

This volume would be the set itself, but I want to do all of this via API.

Where, after selecting the equipment, for example, it creates a selection range, a range predefined by me, where we would have an idea of ​​the size and spacing for selection. Based on the selected piece of equipment.

Was I clear?

Thank you!

Hi @julia_morseP8AHB ,

It seems you are referring to the bounding box.
From my understanding, you are selecting an element from which you would like to obtain the bounding box and then increase its size.
Is that correct?
Could you please clarify if that is the case?
Additionally, it would be helpful if you could provide a screenshot or a brief video to illustrate your point.

[julia_morseP8AHB]

Hi @naveen.kumar.t ,

Let me try to explain it better...

Would this bounding box have an action like the set? Well, I initially thought of the set because I need to attach this "volume" that would be the set itself to a task in the timeliner. Do you understand?

That's why I need to create a set from an item/equipment and from this selection it generates a set with a specific range from the equipment itself.

Hi @julia_morseP8AHB ,

Please note that the Navisworks API rarely supports functionality that isn't available in the UI. Therefore, it's always helpful to identify the optimal manual approach before attempting a programmatic solution.

Based on the referenced help pages, it appears that creating a set from a volume or bounding box in the Navisworks UI is not supported. As a result, the API likely does not offer this functionality either. If you could provide manual instructions for achieving this in the UI, I can further investigate the API possibilities.

In my opinion, it would be possible.
Let's go... for example, don't we manually create a fence in NavisWorks? It is possible to create a fence... and select several objects.

Does this fence have a specific size? What if we created this fence by selecting an item in the model?

I think we can get the idea from this point.

Is that clear?

Hi @julia_morseP8AHB ,

I’m sorry for any confusion.

I still don’t fully understand the issue.

Could you please share a short, non-confidential video explaining the problem and your goal?

I’ll review it and check with my team to help resolve it.

Define boundingBox3D and do search. Then create selectset for the search result.

[julia_morseP8AHB]

Oh, great @tetsuya_miwa, it's a plugin?

I managed to create a preview, where it creates the set from the selection of one or more items.

Next steps:
> define the name of the set from the name of the selected item;
> "select" the item from the corresponding tag in the schedule (timeliner)

See the code now.

using System;
using System.Windows.Forms;
using Autodesk.Navisworks.Api;
using Autodesk.Navisworks.Api.Plugins;

[Plugin("MyNamespace.CreateSetPlugin", "MyCompany", DisplayName = "Create Set from Selection")]
public class CreateSetPlugin : AddInPlugin
{
    public override int Execute(params string[] parameters)
    {
        CreateSetFromSelection();
        return 0;
    }

    private void CreateSetFromSelection()
    {
        Document doc = Autodesk.Navisworks.Api.Application.ActiveDocument;

        if (doc.CurrentSelection.SelectedItems.Count > 0)
        {
            // Cria um novo conjunto de seleção
            SelectionSet newSet = new SelectionSet();
            newSet.DisplayName = "Meu Novo Set"; // Define o nome do conjunto

            // Adiciona os itens selecionados ao novo conjunto
            foreach (ModelItem item in doc.CurrentSelection.SelectedItems)
            {
                newSet.ExplicitModelItems.Add(item); // Adiciona itens explicitamente
            }

            // Tenta adicionar o novo conjunto ao documento
            try
            {
                // Adiciona o conjunto de seleção à coleção de conjuntos de seleção
                doc.SelectionSets.AddCopy(newSet);
                MessageBox.Show($"Set criado com {newSet.ExplicitModelItems.Count} itens.");
            }
            catch (Exception ex)
            {
                MessageBox.Show($"Erro ao adicionar o conjunto: {ex.Message}");
            }
        }
        else
        {
            MessageBox.Show("Nenhum item selecionado.");
        }
    }
}

Hi @naveen.kumar.t  regarding my last answer. Can you help me?

I managed to close the code to create a set after the selection item and append the name of the equipment to the corresponding set.

Now I want to try to create a "fence" after this selection and save it in the set with an additional "volume". Because the final point is to obtain the selection not only of the desired equipment itself, but also of the items next to it.

[naveen.kumar.t]

Hi @julia_morseP8AHB ,

Based on my understanding, here’s what you need to do:

1. Create and save a selection set by choosing the model items.
2. You can retrieve the bounding box using doc.CurrentSelection.SelectedItems.BoundingBox.
3. To expand the bounding box, you can use the following code snippet.
4. You can check if two bounding boxes intersect or if one is contained within another by using the Intersects or Contains methods. Please take a look at these links BoundingBox3D.Contains Method (BoundingBox3D) and BoundingBox3D.Intersects Method
5. By following these steps, you can identify nearby items.

I’ve put together a rough code example (not entirely sure it will solve your issue, but it should give you a good starting point).

 public class Class1 : AddInPlugin                        //Derives from AddInPlugin
 {
     public override int Execute(params string[] parameters)
     {
         MyNwCode();
         return 0;
     }

     private void MyNwCode()
     {
         Document doc = Autodesk.Navisworks.Api.Application.ActiveDocument;
         //Step 1: Create Set from Collection
         CreateSet(doc);
         //Step 2: Get BoundingBox of items in set
         BoundingBox3D boundingBox3D = doc.CurrentSelection.SelectedItems.BoundingBox(true);
         //Step 3: Expand BoundingBox
         int expansionFactor = 20;
         BoundingBox3D expandBoundingBox = ExpandBoundingBox(boundingBox3D, expansionFactor);
         //Step 4: Get Required BoundingBox intersecting Elements
         IEnumerable<ModelItem> requiredElements = BoundingBoxIntersectingElements(doc, expandBoundingBox);
         MessageBox.Show("Intersecting Elements = " + requiredElements.Count().ToString());
     }

     private IEnumerable<ModelItem> BoundingBoxIntersectingElements(Document doc, BoundingBox3D expandBoundingBox)
     {
         doc.CurrentSelection.SelectAll();
         ModelItemCollection collection = doc.CurrentSelection.SelectedItems;
         Search search = new Search();
         search.Selection.SelectAll();
         search.SearchConditions.Add(SearchCondition.HasPropertyByDisplayName("Element ID", "Value"));
         ModelItemCollection allItems = search.FindAll(doc, false);
         IEnumerable<ModelItem> items1 =allItems.Where(y => y.BoundingBox(true).Intersects(expandBoundingBox));
         IEnumerable<ModelItem> items2 = allItems.Where(y => expandBoundingBox.Contains(y.BoundingBox(true)));
         return items2;
     }

     private BoundingBox3D ExpandBoundingBox(BoundingBox3D box, int expansionAmount)
     {
         return new BoundingBox3D(
         new Point3D(box.Min.X - expansionAmount, box.Min.Y - expansionAmount, box.Min.Z - expansionAmount),
         new Point3D(box.Max.X + expansionAmount, box.Max.Y + expansionAmount, box.Max.Z + expansionAmount));
     }

     private void CreateSet(Document doc)
     {
         ModelItemCollection modelItemCollection = doc.CurrentSelection.SelectedItems;
         SavedItem newSelectionSet = new SelectionSet(modelItemCollection);
         newSelectionSet.DisplayName = "MySelectionSet";
         doc.SelectionSets.InsertCopy(0, newSelectionSet);
     }
 }

I hope this helps!

During yesterday and with the help of @tetsuya_miwa  reference I was able to advance in my code.
