Set Selection Resolution

[xaotix]

Is there a way to alter the resolution programmatically?

• File, Layer, First Object, Last Object, Last Unique, Geometry.

Hi @xaotix ,

Please try using the below code

 using (LcUOptionLock optionLock = new LcUOptionLock())
 {
     // Get the root options using the lock
     LcUOptionSet rootOptions = LcUOption.GetRoot(optionLock);

     // Retrieve the pointer to the specific option by name
     LcUNameRefPtr optionPointer = rootOptions.GetName("interface.selection.resolution");

     // Check if the pointer exists before attempting to set the value
     if (optionPointer != null)
     {
         /*
          * Selection Resolution Options:
          *  0 = File
          *  1 = Layer
          *  2 = First Object
          *  3 = Last Unique
          *  4 = Last Object
          *  5 = Geometry
          */

         // Update the selection resolution option to "Geometry" (value 5)
         string resolutionValue = "RoamerGUI_PickResolution:5";
         rootOptions.SetName("interface.selection.resolution", new NamedConstant(resolutionValue));
         LcOpRegistry.SaveGlobalOptions();
     }
 }

For Navisworks Simulate 2024 you can write some code which modifies this registry key:
HKEY_CURRENT_USER\SOFTWARE\Autodesk\Navisworks Simulate\21.0\GlobalOptions\interface\selection

the default value is:
Name: Resolution
Data: 8 26:RoamerGUI_PickResolution:4Last Object

Note that for Navisworks 2024 you alter version 210.0 since Navisworks 2024 is Navisworks version 21

An old post of mine, with all Navisworks Global Settings at the time (Navisworks 2020) and how to read/change them:

Hi @imustafa_adel,

You asked me how to read the value of 'Selection Resolution' (by contacting me via chat message).
Here is the answer.

 using (LcUOptionLock optionLock = new LcUOptionLock())
 {
     // Get the root options using the lock
     LcUOptionSet rootOptions = LcUOption.GetRoot(optionLock);
     LcUNameRefPtr s=rootOptions.GetName("interface.selection.resolution");
     MessageBox.Show(s.GetPtr().ToString());            
 }

I'm posting it here so that others with similar questions can also refer to this thread and find the answer.

Thank you I've also refined the method a little bit as shown below:

public static void SetSelectionResolution(SelectionResolution selectionResolution)
{
          var commandstr = "interface.selection.resolution";
          using (LcUOptionLock optionLock = new LcUOptionLock())
          {
                  LcUOptionSet rootOptions = LcUOption.GetRoot(optionLock);

                  LcUNameRefPtr optionPointer = rootOptions.GetName(commandstr);

                  if (optionPointer != null)
                  {
                          string resolutionValue = "RoamerGUI_PickResolution:2";
                          switch (selectionResolution)
                          {
                                  case SelectionResolution.File:
                                          resolutionValue = "RoamerGUI_PickResolution:0";
                                          break;
                                  case SelectionResolution.Layer:
                                          resolutionValue = "RoamerGUI_PickResolution:1";
                                          break;
                                  case SelectionResolution.FirstObject:
                                          resolutionValue = "RoamerGUI_PickResolution:2";
                                          break;
                                  case SelectionResolution.LastUnique:
                                          resolutionValue = "RoamerGUI_PickResolution:3";
                                          break;
                                  case SelectionResolution.LastObject:
                                          resolutionValue = "RoamerGUI_PickResolution:4";
                                          break;
                                  case SelectionResolution.Geometry:
                                          resolutionValue = "RoamerGUI_PickResolution:5";
                                          break;
                          }
                          rootOptions.SetName(commandstr, new NamedConstant(resolutionValue));
                          LcOpRegistry.SaveGlobalOptions();
                  }
          }
}

public static SelectionResolution GetSelectionResolution()
{
          var res = string.Empty;
          using (LcUOptionLock optionLock = new LcUOptionLock())
          {
                  var commandstr = "interface.selection.resolution";
                  LcUOptionSet rootOptions = LcUOption.GetRoot(optionLock);
                  LcUNameRefPtr optionPointer = rootOptions.GetName(commandstr);
                  var data = new VariantData();
                  var result = rootOptions.GetDataValue(commandstr, data);
                  if (result) res = data.ToNamedConstant().Name;
          }
          switch (res)
          {
                  case "RoamerGUI_PickResolution:0":
                          return SelectionResolution.File;
                  case "RoamerGUI_PickResolution:1":
                          return SelectionResolution.Layer;
                  case "RoamerGUI_PickResolution:2":
                          return SelectionResolution.FirstObject;
                  case "RoamerGUI_PickResolution:3":
                          return SelectionResolution.LastUnique;
                  case "RoamerGUI_PickResolution:4":
                          return SelectionResolution.LastObject;
                  case "RoamerGUI_PickResolution:5":
                          return SelectionResolution.Geometry;
                  default:
                          return SelectionResolution.FirstObject;
          }
}
