【ORD C#】Profile控制点如何获取？

这个是获取横断面控制点的，您应该用GetVerticalControlPoints方法获取纵断面的。

以下是我写的代码，有两个问题：

1. GetVerticalControlPoints的参数不知如何选择

2.GetVertices()是得到所有控制点吗

Profile profile = al.ActiveProfile;
ProfileElement profileGeometry =profile.ProfileGeometry;
CurveVector curveVector = profileGeometry.GetCurveVector();
LinearElement linear = LinearElement.CreateFromCurveVector(curveVector, true);
LinearPointCollection coll = linear.GetVerticalControlPoints(VerticalControlPointTypes.Curve_Line);
DPoint3d[] pts = coll.GetVertices();

1.具体设置参数我找到C++的，.net没有封装那么多，但基本都在C++有介绍，里面对每个参数都有解释：

public enum class VerticalControlPointTypes : int
{
    /// High point in profile.
    /// </summary>
    High_Point = BC_VERT_CTRLPT_VHP,
    /// <summary>
    /// Low point in profile.
    /// </summary>
    Low_Point = BC_VERT_CTRLPT_VLP,
    /// <summary>
    /// Start point and end point in profile.
    /// </summary>
    StartEnd_Point = BC_VERT_CTRLPT_VPI,
    /// <summary>
    /// Point of intersection for curve.
    /// </summary>
    Curve_PI = BC_VERT_CTRLPT_VC_VPI,
    /// <summary>
    /// Connection point of line and curve.
    /// </summary>
    Line_Curve = BC_VERT_CTRLPT_VC_VPC,
    /// <summary>
    /// Connection point of curve and line.
    /// </summary>
    Curve_Line = BC_VERT_CTRLPT_VC_VPT,
    /// <summary>
    /// Point of intersection for sag curve.
    /// </summary>
    SagCurve_PI = BC_VERT_CTRLPT_VC_VPI_SAG,
    /// <summary>
    /// Point of intersection point for crest curve.
    /// </summary>
    CrestCurve_PI = BC_VERT_CTRLPT_VC_VPI_CST,
    /// <summary>
    /// Connection point of line and sag curve.
    /// </summary>
    Line_SagCurve = BC_VERT_CTRLPT_VC_VPC_SAG,
    /// <summary>
    /// Connection point of line and crest curve.
    /// </summary>
    Line_CrestCurve = BC_VERT_CTRLPT_VC_VPC_CST,
    /// <summary>
    /// Connection point of sag curve and line.
    /// </summary>
    SagCurve_Line = BC_VERT_CTRLPT_VC_VPT_SAG,
    /// <summary>
    /// Connection point of crest curve and line.
    /// </summary>
    CrestCurve_Line = BC_VERT_CTRLPT_VC_VPT_CST,
};

2.当您获取LinearPointCollection 您可以遍历该数组，获取每个LinearPoint ，GetVertices是获取每个顶点，也就是您数组里面的点坐标（DPoint3d）：

foreach(LinearPoint lp in linearPtCollection)

感谢老师解答，按照你给的linearPtCollection遍历方式去获取控制点，我把所有的VerticalControlPointTypes类型都试了一遍，发现遍历结果都为空

您把模型给我发下邮箱：xiaoqi.zhang@bentley.com,您是要获取模型某一条alignment的profile的控制点是吗？邮箱给我说明下，谢谢。
