is there a way to add a link to an object via .net? wanting to look thru all the mechanical equipment on our models and link them to their documentation automatically. thanks!

Hi,

To add hyperlink to the object, COM API is the current way, i.e. use COM interop in the .NET  program. The code below adds some links to one object.

 private void AddURL()
  { 
  ComApi.InwOpState10 state;
  state = ComApiBridge.ComApiBridge.State;

  ComApi.InwURLOverride oMyURLOoverride = (ComApi.InwURLOverride)state.ObjectFactory(Autodesk.Navisworks.Api.Interop.ComApi.nwEObjectType.eObjectType_nwURLOverride, null, null);

  double[] coordinate = { 10, 10, 0, 20, 20, 0, 30, 30, 0 };

  for(int i = 0 ;i < 9; i +=3)
  {
  ComApi.InwURL2 oMyURL = (ComApi.InwURL2)state.ObjectFactory(Autodesk.Navisworks.Api.Interop.ComApi.nwEObjectType.eObjectType_nwURL, null, null);
  oMyURL.name = "MyURL" + i.ToString ();
  oMyURL.URL = "http://www.google.com";

  ComApi.InwLPos3f oNewP = (ComApi.InwLPos3f)state.ObjectFactory(Autodesk.Navisworks.Api.Interop.ComApi.nwEObjectType.eObjectType_nwLPos3f, null, null);

  oNewP.data1 = coordinate[i];
  oNewP.data2 = coordinate[i + 1];
  oNewP.data3 = coordinate[i + 2];
 
  oMyURL.AttachmentPoints().Add(oNewP);

 
  ComApi.InwURLColl oURLColl = oMyURLOoverride.URLs(); 
  oURLColl.Add(oMyURL);

   ModelItemCollection modelItemCollectionIn = new ModelItemCollection(Autodesk.Navisworks.Api.Application.ActiveDocument.CurrentSelection.SelectedItems);

  //convert to InwOpSelection of COM API
  ComApi.InwOpSelection comSelectionOut =
  ComApiBridge.ComApiBridge.ToInwOpSelection(modelItemCollectionIn);

 
  state.SetOverrideURL(comSelectionOut, oMyURLOoverride);
  state.URLsEnabled = true; 
  }
  return;
  }

Best regards,

Hi,

Is there a way to find the coordinate of an element in Navisworks? I tried to find the coordinate of an element to put a label directly on it.  I know that it is possible to find the boundingbox of the element with the API but it seems that the element is not always in the center of the bounding box.

Thanks

Hi Xiaodong,

    I am attemping to create the add links to object programatically using either vbscript or javascript for usage in the Integrated ActiveX control embedded in a HTML page. I have debugged the code and it runs through to the end but the featured selection in my model is not updated with a manual link I have created. Can you point out where I am going wrong. Both code samples are provided below: I believe the area it is falling down relates to the actual state.SetOverrideURL call using InwOpSelection paramter. I cannot recreate the ModelItemCollection in VBScript or Javascript so have tried  a number of approaches to pass CurrentSelection.SelectedItems

VBSCRIPT

public sub addURL()

Dim state

Set state = NWControl01.state

Dim oMyURLOoverride Set oMyURLOoverride = state.ObjectFactory(state.GetEnum ("eObjectType_nwURLOverride"))

 // Dim coordinate = "10, 10, 0, 20, 20, 0, 30, 30, 0"

Dim coordinate coordinate = "1"

Dim oMyURL    

Set oMyURL = state.ObjectFactory(state.GetEnum("eObjectType_nwURL"))  

oMyURL.name = "MyURL444"  

oMyURL.URL = "http://www.google.co.uk"

oMyURL.SetCategory "Hyperlink","LcOaURLCategoryHyperlink"        

 oMyURL.SetCategory "Label", "LcOaURLCategoryTag"

  Dim oNewP

  Set oNewP = state.ObjectFactory(state.GetEnum("eObjectType_nwLPos3f"))

  oNewP.data1 = "10"  

  oNewP.data2 = "10"  

  oNewP.data3 = "0"

oMyURL.AttachmentPoints().Add(oNewP)

 Dim oURLColl

  Set oURLColl = oMyURLOoverride.URLs   oURLColl.Add(oMyURL)

    //convert to InwOpSelection of COM API  

Dim comSelectionOut

 Set comSelectionOut = state.CurrentSelection

state.SetOverrideURL comSelectionOut, oMyURLOoverride  

state.URLsEnabled = true

state.ZoomInCurViewOnCurSel

end sub

-->

JAVASCRIPT&colon;

function addURL() {

var state = NWControl01.state;

var oMyURLOoverride = state.ObjectFactory( state.GetEnum( "eObjectType_nwURLOverride"),null, null);

  var coordinate = "10, 10, 0, 20, 20, 0, 30, 30, 0 ";

    var oMyURL = state.ObjectFactory(state.GetEnum("eObjectType_nwURL"),  null, null);  

oMyURL.name = "MyURL444";  

oMyURL.URL = "http://www.google.co.uk";

oMyURL.SetCategory("Hyperlink", "LcOaURLCategoryHyperlink");

 oMyURL.SetCategory("Label", "LcOaURLCategoryTag");

  var oNewP = state.ObjectFactory(state.GetEnum("eObjectType_nwLPos3f"), null, null);

  oNewP.data1 = "10";  

  oNewP.data2 = "10";  

  oNewP.data3 = "0";

    oMyURL.AttachmentPoints().Add(oNewP);

    var oURLColl = oMyURLOoverride.URLs();   oURLColl.Add(oMyURL);

    //convert to InwOpSelection of COM API  

var comSelectionOut = state.ObjectFactory(state.GetEnum("eObjectType_nwOpSelection"));

// state.CurrentSelection.SelectedItems;

    state.SetOverrideURL(comSelectionOut, oMyURLOoverride);  

state.URLsEnabled = true;

state.ZoomInCurViewOnCurSel();

}
