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); } } } } } /// /// 递归判断结构树信息 /// /// 数据源信息 /// 父级节点信息 /// 子节点信息 private void LoadChild(IEnumerable modelItemEnumerableCollection, ModelItem parentItem, TreeNode pNode) { var query = modelItemEnumerableCollection.Where(o => o.Parent == parentItem); if (query.Count()>0) { 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(176,196,222),Autodesk.Navisworks.Api.Color.FromByteRGB(176,196,166)); //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[0]; 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); } } } } #endregion 最终效果：
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。
