How can we traverse through all the components in a Navisworks file using the .NET API?
To traverse through all the components in the model, you can use the following simple approach to iterate through each model item.
using System.Collections.Generic;
using System.Text;
//Add two new namespaces
using Autodesk.Navisworks.Api;
using Autodesk.Navisworks.Api.Plugins;
namespace BasicPlugIn
{
[PluginAttribute("BasicPlugIn.ABasicPlugin",
"ADSK",
ToolTip = "BasicPlugIn.ABasicPlugin tool tip",
DisplayName = "Sample Plugin")]
public class ABasicPlugin : AddInPlugin
{
public override int Execute(params string[] parameters)
{
foreach (ModelItem item in
Autodesk.Navisworks.Api.Application
.ActiveDocument.Models.RootItemDescendantsAndSelf)
{
System.Diagnostics.Trace.WriteLine(
"Display Name: " + item.DisplayName +
"; Class Display Name: " + item.ClassDisplayName +
"\n");
}
return 0;
}
}
}
Just as a warning – this approach can be little slow and if you are traversing to access a specific item, please use the Search APIs.
