新生成的管道会是Origin 和打断位置的这一段，原先的会是剩下那一段。通过设置Dimension的IsLocked属性在隐藏尺寸标注实现约束效果。

1.引用Windows user32.dll方法 public static class WindowAPI { #region 窗口聚焦 [DllImport("user32.dll")] public static extern IntPtr GetActiveWindow(); [DllImport("user32.dll")] public static extern IntPtr SetAct

1.通过solid信息构建相交过滤器过滤图元public List<Element> GetIntersectsElements(Solid solid, Document doc) { //solid的boundingbox是局部坐标矩阵转换为世界坐标系 Transform transform = solid.GetBoundingBox().Transform; XYZ minSolid = sol

1.获取或构建一个Solid，调用Solid下ComputeCentroid获取质点 Solid roomSolid = GeometryCreationUtilities.CreateExtrusionGeometry(RoomCurveLoops, XYZ.BasisZ, 1); XYZ centroid = roomSolid.ComputeCentroid(); centroid = centroid.NewZ(locat

1.判断点位置顺时针方向 /// <summary> /// 若a大于点b，即点a在b顺时针方向 ，返回true，否则false /// </summary> /// <param name="a"></param> /// <param name="b"></param> /// <param name="center">

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { Document document = commandData.Application.ActiveUIDocument.Document; UIApplication uIApplication = commandData.Application;.

1.创建三维视图/// <summary> /// 创建标注三维视图 /// </summary> /// <param name="doc"></param> private View3D Create3DView(Document doc) { List<Category> categories = new List<Catego

ViewPlan activeView = viewPlan; PlanViewRange pvr = activeView.GetViewRange(); Level NowLevel = activeView.GenLevel;//当前标高 Level TopClipPlaneLevel = doc.GetElement(pvr.GetLevelId(PlanViewPlane.TopClipPlane)) as Level ?.

/// <summary> /// 获取墙平行的面 /// </summary> /// <param name="wall">墙</param> /// <param name="transform">转换矩阵</param> /// <returns></returns> private Lis...

链接文件的Reference有两种方式：1.射线法：通过射线方式获取找到链接文件的元素，可以取出到射到面的Reference2.构造法：通过链接文件的元素Reference获取 ConvertToStableRepresentation字符串（ new Reference(wall). CreateLinkReference(revitLink).ConvertToStableRepresentation(doc) ），然后通过Lookup 查看Revit上手动标注出链接文件元素标注获取Conver
