Hello!

Сould you tell me please how to select modelItem from Quantification using Navisworks API? 

I can select a row in the table using this information from api:

void SelectElement(long elId)
{
TakeoffSelection takeoffSelection = Autodesk.Navisworks.Api.Application.ActiveDocument.GetTakeoff().CurrentSelection;
takeoffSelection.BeginEdit();
takeoffSelection.Objects.Clear();
takeoffSelection.Objects.Add(elId);
takeoffSelection.EndEdit();
}

But element in model is not select

Thanks for any answers:)

You need to use sql request to find ModelItemId and get GUID
