使用SOLIDWORKS API在绘图视图中选择实体
{ width=300 }
该示例演示了使用SOLIDWORKS API在绘图视图中选择实体(例如边、面、顶点)的不同方法。
- 通过直接使用IView:SelectEntity方法在目标视图中选择实体。当需要选择实体而不需要传递任何额外数据(例如选择标记或标注)时,此方法非常有用。
- 通过在选择数据中指定视图来选择实体,使用的是ISelectData::View SOLIDWORKS API属性。与前一种方法相比,这种方法更加灵活,因为可以提供更多的选择信息。
- 选择可见实体。这种方法允许在绘图视图的上下文中查找实体。其主要优点是它只会尝试选择当前视图方向中可见的实体,而前两种方法不考虑实体被其他实体遮挡的情况。
- 要运行宏,请下载示例模型和绘图。
- 在零件文档中,圆形边缘被命名为Hole。
{ width=300 }
- 运行宏后,此边缘将在所有3个视图中使用上述3种不同的方法被选择。
Const ENT_NAME As String = "Hole"
Dim swApp As SldWorks.SldWorks
Dim swDraw As SldWorks.DrawingDoc
Sub main()
Set swApp = Application.SldWorks
Set swDraw = swApp.ActiveDoc
Dim swView1 As SldWorks.view
Dim swView2 As SldWorks.view
Dim swView3 As SldWorks.view
Set swView1 = swDraw.FeatureByName("Drawing View1").GetSpecificFeature()
Set swView2 = swDraw.FeatureByName("Drawing View2").GetSpecificFeature()
Set swView3 = swDraw.FeatureByName("Drawing View3").GetSpecificFeature()
Dim swRefDoc As SldWorks.PartDoc
Set swRefDoc = swView1.ReferencedDocument
Dim swEdge As SldWorks.Edge
Set swEdge = swRefDoc.GetEntityByName(ENT_NAME, swSelectType_e.swSelEDGES)
swDraw.ClearSelection2 True
SelectInView swView1, swEdge
SelectInViewBySelData swView2, swEdge
SelectFromVisibleEntities swView3
End Sub
Sub SelectInView(view As SldWorks.view, ent As SldWorks.Entity)
view.SelectEntity ent, True
End Sub
Sub SelectInViewBySelData(view As SldWorks.view, ent As SldWorks.Entity)
Dim swSelMgr As SldWorks.SelectionMgr
Dim swSelData As SldWorks.SelectData
Set swSelMgr = swDraw.SelectionManager
Set swSelData = swSelMgr.CreateSelectData
swSelData.view = view '指定要在其中选择实体的视图
ent.Select4 True, swSelData
End Sub
Sub SelectFromVisibleEntities(view As SldWorks.view)
Dim vVisComps As Variant
vVisComps = view.GetVisibleComponents()
Dim vVisEnts As Variant
vVisEnts = view.GetVisibleEntities2(vVisComps(0), swViewEntityType_e.swViewEntityType_Edge)
Dim i As Integer
For i = 0 To UBound(vVisEnts)
Dim swEdge As SldWorks.Entity
Set swEdge = vVisEnts(i)
If swEdge.ModelName = ENT_NAME Then
swEdge.Select4 True, Nothing '不需要显式指定要选择的视图,因为实体的指针已经属于该视图
Exit Sub
End If
Next
End Sub
