老师您好，我首先在ORD里面画了一条线，并且激活了纵断面，然后在代码中直接获取这条线元素alignment，用来创建廊道，但是得到的newCorridor为空。
CorridorEdit newCorridor = CorridorEdit.CreateByAlignment(con, name, alignment);
请用下面代码测试一下：
public static AlignmentEdit CreateCorridorFromLine () { //创建两条直线 double beginHeight = 3.5, profileSlope = 0.02; double mUor = Session.Instance.GetActiveDgnModel().GetModelInfo().UorPerMeter; List<Line> lineList1 = new List<Line>(); List<Line> lineList2 = new List<Line>(); Line line1 = new Line(DPoint3d.FromXYZ(0, 0, 0), DPoint3d.FromXYZ(10 * mUor, 0, 0)); Line line2 = new Line(DPoint3d.FromXYZ(0, 15 * mUor, 0), DPoint3d.FromXYZ(10 * mUor, 15 * mUor, 0)); lineList1.Add(line1); lineList2.Add(line2); LinearComplex complexAlign1 = LinearComplex.Create1(lineList1.ToArray(), false, false, 0.001); LinearComplex complexAlign2 = LinearComplex.Create1(lineList2.ToArray(), false, false, 0.001); ConsensusConnectionEdit con = ConsensusConnectionEdit.GetActive(); con.StartTransientMode(); AlignmentEdit align1 = AlignmentEdit.CreateByLinearElement(con, complexAlign1, true); AlignmentEdit align2 = AlignmentEdit.CreateByLinearElement(con, complexAlign2, true); if ( null == align1 || null == align2 ) return null; //特征属性 List<string> featureNames = new List<string>(); FeatureDefinitionManager fdm = FeatureDefinitionManager.Instance; featureNames.AddRange(fdm.GetFeatureDefinitions(ConsensusConnectionEdit.GetActive(), "Alignment")); string featureName = ""; if ( featureNames.Count > 0 ) featureName = featureNames[0]; align1.SetFeatureDefinition(featureName); align2.SetFeatureDefinition(featureName); //创建纵面 ProfileLine profileLine = new ProfileLine(DPoint3d.FromXYZ(0, beginHeight * mUor, 0), DPoint3d.FromXYZ(align1.LinearGeometry.Length , align1.LinearGeometry.Length * profileSlope + beginHeight * mUor, 0));
