从选择集中加入实体

大家好！
我想尝试用JoinEntity()方法连接多段线。我的想法是在一个选择集中收集所有的三维折线，然后函数寻找在不同三维折线的起点或/和终点的实体(三维折线)。我在想什么，在Lisp中，它有能力通过ssget-function选择不同的对象。我不知道，怎么办。网？！所以也许有可能找到正确的三维折线来连接它们？！
**** Hidden Message ***** 您好，
也许您可以从PolylineSegmentCollection中获得一些灵感。GeometryExtensions中的Join（）方法。 嗨，Gile！
谢谢。
我在C：\Windows\Microsoft.NET\Framework中没有找到引用Geometry扩展。我必须在哪里寻找它们？！
对不起，瞎了 点击我回复中的链接。 伟大的工作Gile，我必须阅读 - 它非常适合2D绘图对象 - 我尝试了你的函数“mjoin”与GeometryExtensions 嗨，吉尔！
1...它有什么理由为什么不在以下位置使用 JoinEntity：Autodesk.AutoCAD.DatabaseServices.Entity.JoinEntity（Autodesk.AutoCAD.DatabaseServices.Entity）
2...对我来说很难理解（在Acad API中有几个月的时间经验）类GeometryExtensions中的所有metods，你能解释一下，你如何加入例如Polylines（在你的情况下2d）
3...如果我尝试为Polyline3d设置PolylineSegmentCollection，我必须收集哪些属性我不确定
如何在AcadDB中命令“mjoin”中加入新的Polylines， 您是否正在删除并构建新的Polyline2d？！
抱歉有不好的问题，我是新手
A 第一次试用
public PolylineSegmentCollection(Polyline3d pline)
{
ObjectId[] vertices = pline.Cast().ToArray();
//PolylineVertex3d[] vertices = pline.Cast().ToArray();
int n = vertices.Length - 1;
for (int i = 0; i ().ToArray();
ed.WriteMessage("\nNumber of vertexes: {0}", verts.Length);
for (int i = 0; i < verts.Length; i++)
{
PolylineVertex3d vt = tr.GetObject(verts, OpenMode.ForRead) as PolylineVertex3d;
coll.Add(new Point3d(vt.Position, vt.Position, vt.Position));
}
tr.Commit();
}
return coll;
}
static public void Append3dPolylines()
{
Document doc = Application.DocumentManager.MdiActiveDocument;
Editor ed = doc.Editor;
Database db = doc.Database;
Point3dCollection collPoint3d = null;
Point3dCollection allPoint3d = null;
PromptEntityOptions peo1 = new PromptEntityOptions("\nSelect source polyline : ");
peo1.SetRejectMessage("\nInvalid selection...");
peo1.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d), true);
PromptEntityResult res = ed.GetEntity(peo1);
if (PromptStatus.OK != res.Status)
return;
using (Transaction trans = db.TransactionManager.StartTransaction())
{
BlockTable BlkTbl = trans.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;
BlockTableRecord BlkTblRec = trans.GetObject(BlkTbl, OpenMode.ForWrite) as BlockTableRecord;
Polyline3d newPoly = new Polyline3d();
BlkTblRec.AppendEntity(newPoly);
trans.AddNewlyCreatedDBObject(newPoly, true);
try
{
collPoint3d = GetVertex(res);
allPoint3d = new Point3dCollection();
foreach (Point3d pt in collPoint3d)

也许这个试验也应该在Selectionset中工作。选择3dPolyline简单，如果在start或endpoint
之后选择3dPolyline也没关系。请测试它，也许您知道它如何在Selectionset中工作。在那里，它必须检查start或endpoint
static public void join3d()
{
Document document = Application.DocumentManager.MdiActiveDocument;
Editor ed = document.Editor;
Database db = document.Database;
PromptEntityOptions peo1 = new PromptEntityOptions("\nSelect source polyline : ");
peo1.SetRejectMessage("\nInvalid selection...");
peo1.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline), true);
peo1.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline2d), true);
peo1.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d), true);
PromptEntityResult res = ed.GetEntity(peo1);
if (PromptStatus.OK != res.Status)
return;
ObjectId srcId = res.ObjectId;
while (true)
{
PromptEntityOptions peo2 = new PromptEntityOptions("\nSelect polyline to join : ");
peo2.SetRejectMessage("\nInvalid selection...");
peo2.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline), true);
peo2.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline2d), true);
peo2.AddAllowedClass(typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d), true);
res = ed.GetEntity(peo2);
switch (res.Status)
{
case PromptStatus.OK:
ObjectId joinId = res.ObjectId;
try
{
using (Transaction trans = db.TransactionManager.StartTransaction())
{
Entity srcPLine = trans.GetObject(srcId, OpenMode.ForRead) as Entity;
Entity addPLine = trans.GetObject(joinId, OpenMode.ForRead) as Entity;
srcPLine.UpgradeOpen();
srcPLine.JoinEntity(addPLine);
addPLine.UpgradeOpen();
addPLine.Erase();
trans.Commit();
}
}
catch (System.Exception ex)
{
ed.WriteMessage(ex.Message);
}
break;
case PromptStatus.Cancel:
ed.WriteMessage("\nFinished!");
return;
}
}
}
中的3dPolyline ErrorStatus=AlreadyInDB
我收到此异常，无法理解。有人能理解并解决吗
在poly中。附加顶点（vex3d）；不对劲。
using (Transaction tr = db.TransactionManager.StartTransaction())
{
try
{
Polyline3d poly = new Polyline3d();
btr.AppendEntity(poly);
tr.AddNewlyCreatedDBObject(poly, true);
foreach (Polyline3DPoints segs in psc)
{
Entity pline = (Entity)tr.GetObject(segs.ObjectID, OpenMode.ForWrite);
foreach (ObjectId vId in (Polyline3d)pline)
{
PolylineVertex3d vex3d = (PolylineVertex3d)tr.GetObject(vId, OpenMode.ForRead);
poly.AppendVertex(vex3d);
tr.AddNewlyCreatedDBObject(vex3d, true);
}
}
}
catch (System.Exception ex)
{ }
tr.Commit();
您好，
您必须为新的Polyline3d（多边形）创建新的polylinevertex3d。现在，您正在尝试将不同的多段线（psc、pline）顶点（vId）设置为新的
我不知道psc集合中有什么，但我预计会有Polyline3d的集合。
