Pipe created with some problem in some complicated situation.

Anonymous — Mon, 01 Jul 2019 04:50:09 GMT

I want to write a function to break pipe,this function has no problem in pipe without many pipe fittings.

Are pipe fittings effecting the pipe? If they are, How can I fix that.

if (projectFirstPoint.DistanceTo(pipeCurve.Curve.GetEndPoint(0)) < projectSecondPoint.DistanceTo(pipeCurve.Curve.GetEndPoint(0)))
            {
                newCurve1 = Line.CreateBound(pipeCurve.Curve.GetEndPoint(0), projectFirstPoint) as Curve;
                newCurve2 = Line.CreateBound(projectSecondPoint, pipeCurve.Curve.GetEndPoint(1)) as Curve;
            }
            else
            {
                newCurve1 = Line.CreateBound(pipeCurve.Curve.GetEndPoint(1), projectFirstPoint) as Curve;
                newCurve2 = Line.CreateBound(projectSecondPoint, pipeCurve.Curve.GetEndPoint(0)) as Curve;
            }

Pipe copyPipe = doc.GetElement(ElementTransformUtils.CopyElement(doc, pipe.Id, new XYZ(0, 0, 0)).ElementAt(0)) as Pipe;
                    copyPipeCurve = copyPipe.Location as LocationCurve;

pipeCurve.Curve = newCurve1;
copyPipeCurve.Curve = newCurve2;

可以提供 .rvt 工程文档，以及更加完整的代码吗？不太理解

projectFirstPoint
projectSecondPoint

两个变量的意思。

Could you pls supply .rvt document, as we as more complete code snippet, so as to help me understand your procedure.

            XYZ firstPoint = selection.PickPoint("请选择第一个打断点");
            XYZ projectFirstPoint = pipeCurve.Curve.Project(firstPoint).XYZPoint;
            XYZ secondPoint = selection.PickPoint("请选择第二个打断点");
            XYZ projectSecondPoint = pipeCurve.Curve.Project(secondPoint).XYZPoint;

下面是我测试的Revit文件，但该错误在任何文件都是可重现的，我怀疑可能是管件影响了程序定义的管道长度。

The error could happen in any document，I think the length of pipe has changed by the pipe fittings .

不要用赋值 LocationCurve.Curve 的方法改变一个管线的位置，这种处理方法有很多错误。

如果只在长度方向上改变一个直管线的长度，那么首先检查 End Connector 有没有连接。没有连接的话，直接改变 Connector.Origin 属性（沿着管线的方向），在Commit()之后会重新生成管线的实体模型。如果连接着的话，强行改变 Origin 会让管线末端和连接件Origin不再重合，你可以试试。

！！！

要用 ElementTransformUtils.Copy() 和 Move() 方法。你想把一个直管线打断成两段，如果 GetEndPoint(1)端是连接的，则应先断开连接，复制原始管线（新复制出来的管线两端都是未连接的），改变 oldPipe的 1 端Connector.Origin，还有 newPipe的 0 端Connector.Origin。记得把 newPipe 的 1 端重新连接到原始的连接。

你的Post 里面的生成错误应该 oldPipe 两边还有连接的情况下，直接改变位置，Revit在Commit()时会尝试重新生成模型。

任何可能修改MEPCurve 图元位置和长度的操作，都要记得检查一下 GetEndPoint(1) - GetEndPoint(0) 向量方向在修改之后是否还有初始的方向相同。

连接件的连接和断开都需要提供和该连接件连接的另一个连接件。

请问用什么方式才能才能获取到另一个连接件？

刚接触二次开发，卡在这里了，还请指点。

Both the connection and the disconnection of the connector require the provision of another connector.

How can I use to get another connector?

用RevitLookup逐个检查，总结规律

哈哈，都是国内的哈，金工是上海哪家单位的呢？

我是自由程序猿，自己研究研究Revit开发的
