RevitAPI: 调用NewExtrusion的时候抛出异常 One of the conditions for the inputs was not satisfied

当调用Document.FamilyCreate.NewExtrusion的时候，可能会抛出下面的异常

Autodesk.Revit.Exceptions.ArgumentException: One of the conditions for the inputs was not satisfied. Consult the documentation for requirements for each argument.

这个很有可能是因为您传入的profile和normal不垂直，也就是形状和拉伸方向不垂直。

例如自己的代码可能是这么写的：

// Create a rectangle profileCurveArrArray profile = new CurveArrArray();CurveArray ca = new CurveArray();XYZ[] points = new XYZ[] {    new XYZ(10, 0, 0),    new XYZ(20, 0, 0),    new XYZ(20, 0, 10),    new XYZ(10, 0, 10)};for (int ii = 0; ii < points.Length; ii++){    var point = points[ii];    var point2 = points[ii == points.Length - 1 ? 0 : ii + 1];    ca.Append(Line.CreateBound(point, point2));}profile.Append(ca);// create the plane normal is perpendicular with profileSketchPlane sketchplane = SketchPlane.Create(doc,     new Plane(XYZ.BasisZ, XYZ.Zero));Extrusion solid = doc.FamilyCreate.NewExtrusion(    true, profile, sketchplane, 20);

实际上注意到SketchPlane的normal是向上的也就是和Z轴垂直，而profile和Y轴垂直，

所以，创建SketchPlane的代码应该是这样的：

SketchPlane sketchplane = SketchPlane.Create(doc,     new Plane(XYZ.BasisY, XYZ.Zero));
