初次接触Navisworks Api .NET 的二次开发.主要是研究了一下。关于NavisWorks 结构树的加载.
void LoadModel()
{
//清空当前的结构树信息
treeView1.Nodes.Clear();
//当前加载的模型
Document doc = Autodesk.Navisworks.Api.Application.ActiveDocument; //循环现有模型
foreach (var documentModel in doc.Models)
{ var modelItemList = documentModel.RootItem.Descendants;
Model model = documentModel;
var modelItems = modelItemList.Where(o => o.Parent == model.RootItem); if (modelItems.Any())
{
TreeNode cNode;
foreach (var quItem in modelItems)
{
cNode = new TreeNode(quItem.DisplayName);
cNode.Tag = quItem;
// cNode.Text = quItem.DisplayName;//判断名称
treeView1.Nodes.Add(cNode);
if (quItem.Children.Any())
{
LoadChild(quItem.Children, quItem, cNode);
} }
} } } /// <summary>
/// 递归判断结构树信息
/// </summary>
/// <param name="modelItemEnumerableCollection">数据源信息</param>
/// <param name="parentItem">父级节点信息</param>
/// <param name="pNode">子节点信息</param>
private void LoadChild(IEnumerable<ModelItem> modelItemEnumerableCollection, ModelItem parentItem, TreeNode pNode)
{
var query = modelItemEnumerableCollection.Where(o => o.Parent == parentItem);
if (query.Count()>)
{
foreach (var quItem in query)
{
TreeNode chNode = new TreeNode(quItem.DisplayName);
chNode.Tag = quItem;
pNode.Nodes.Add(chNode);
if (quItem.Children.Any())
{
LoadChild(quItem.Children, quItem, chNode);
} }
}
}
TreeView Node 选中事件
void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
TreeNode node = e.Node;
if (node != null)
{
ModelItem oCurrentNode = (ModelItem)node.Tag;
propertyGrid1.SelectedObject = oCurrentNode;
if (oCurrentNode != null)
{ //设置选择集合
ModelItemCollection oMC = new ModelItemCollection();
oMC.Add(oCurrentNode);
Document oDoc = view.ViewControl.DocumentControl.Document;
//设置选中
oDoc.CurrentSelection.CopyFrom(oMC);
}
}
}
模型加载窗口：
public partial class FrmModelView : DevExpress.XtraEditors.XtraForm
{
public ViewControl ViewControl;
public FrmModelView()
{
InitializeComponent();
if (this.components == null)
this.components = new Container();
//初始化Document控件
DocumentControl document = new DocumentControl(this.components);
document.Document.SetGraduatedBackground(Autodesk.Navisworks.Api.Color.FromByteRGB(,,),Autodesk.Navisworks.Api.Color.FromByteRGB(,,));
//初始化View控件 并添加Document控件
ViewControl = new ViewControl();
ViewControl.DocumentControl = document;
ViewControl.BackColor = System.Drawing.Color.LightSteelBlue;
ViewControl.Dock = DockStyle.Fill;
ViewControl.Name = "viewControl";
this.Controls.Add(ViewControl);
}
}
模型选择事件：
#region 模型选择事件
private void CurrentSelection_Changed(object sender, EventArgs e)
{
try
{
Document doc = (Document)sender;
if (doc != null)
{
var item = doc.CurrentSelection.SelectedItems[];
if (item != null)
{
TreeNode tnRet = null;
foreach (TreeNode tn in treeView1.Nodes)
{
tnRet = FindNode(tn, item.DisplayName);
if (tnRet != null)
break;
}
if (tnRet != null)
{
if (oldNode != null)
oldNode.BackColor = Color.White;
tnRet.BackColor = Color.YellowGreen;
treeView1.SelectedNode = tnRet;
oldNode = tnRet;
GetProperty();
}
}
}
}
catch (Exception exception)
{
Console.WriteLine(exception);
}
}
#endregion模型的属性加载：
#region 属性信息加载
void GetProperty()
{
//验证模型
if (Autodesk.Navisworks.Api.Application.ActiveDocument != null &&
!Autodesk.Navisworks.Api.Application.ActiveDocument.IsClear)
{
this.vGridControl1.Rows.Clear();
// 获取选中的相关的模型信息
foreach (ModelItem item in Autodesk.Navisworks.Api.Application.ActiveDocument.CurrentSelection.SelectedItems)
{
//获取想的模型属性信息
foreach (PropertyCategory category in item.PropertyCategories)
{
CategoryRow categoryRow=new CategoryRow(category.DisplayName);
foreach (var control in category.Properties)
{
EditorRow row1 = new EditorRow();
row1.Properties.FieldName = "Value";
row1.Properties.Caption = control.DisplayName;
var itemValue = control.Value;
string valueInfo;
switch (itemValue.DataType)
{
case VariantDataType.Boolean:
valueInfo = itemValue.ToBoolean().ToString();
break;
case VariantDataType.DateTime:
valueInfo = itemValue.ToDateTime().ToString(CultureInfo.InvariantCulture);
break;
case VariantDataType.DisplayString:
valueInfo = itemValue.ToDisplayString();
break;
case VariantDataType.Double:
valueInfo = itemValue.ToDouble().ToString();
break;
case VariantDataType.DoubleAngle:
valueInfo = itemValue.ToDoubleAngle().ToString();
break;
case VariantDataType.DoubleArea:
valueInfo = itemValue.ToDoubleArea().ToString();
break;
case VariantDataType.DoubleLength:
valueInfo = itemValue.ToDoubleLength().ToString();
break;
case VariantDataType.DoubleVolume:
valueInfo = itemValue.ToDoubleVolume().ToString();
break;
case VariantDataType.IdentifierString:
valueInfo = itemValue.ToIdentifierString();
break;
case VariantDataType.Int32:
valueInfo = itemValue.ToInt32().ToString();
break;
default:
valueInfo = itemValue.ToString();
break;
}
row1.Properties.Value = valueInfo;
categoryRow.ChildRows.Add(row1);
}
this.vGridControl1.Rows.Add(categoryRow);
}
}
}
}

主要是刚接触这个.不懂 只是自己在这写的。如果那位网友有更好的解决方案。请告诉我.谢谢哈。
