Autodesk.Revit.DB.CurveByPoints是Revit API中的一个类,用于创建由给定点数组构成的曲线。
首先需要引入命名空间Autodesk.Revit.DB,然后创建一个由点对象构成的点数组,然后用点数组实例化CurveByPoints对象,如下所示:
// 创建点数组
List<XYZ> points = new List<XYZ>();
points.Add(new XYZ(0, 0, 0));
points.Add(new XYZ(10, 10, 0));
// 用点数组实例化CurveByPoints对象
CurveByPoints curve = CurveByPoints.Create(points);
也可以通过CurveByPoints.Create获得更多的选项,如设置曲线的法线方向、是否平滑过渡等,如下所示:
// 创建点数组
List<XYZ> points = new List<XYZ>();
points.Add(new XYZ(0, 0, 0));
points.Add(new XYZ(10, 10, 0));
// 设置曲线的法线方向
XYZ normal = XYZ.BasisZ;
// 设置是否平滑过渡
bool isSmooth = true;
// 用点数组、法线方向和是否平滑过渡实例化CurveByPoints对象
CurveByPoints curve = CurveByPoints.Create(points, normal, isSmooth);
CurveByPoints对象的常用属性如下:
CurveByPoints对象的常用方法如下:
以下是创建一个CurveByPoints对象的示例:
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
public void CreateCurveByPoints()
{
Document doc = RevitApp.ActiveUIDocument.Document;
// 创建点数组
List<XYZ> points = new List<XYZ>();
points.Add(new XYZ(0, 0, 0));
points.Add(new XYZ(10, 10, 0));
// 用点数组实例化CurveByPoints对象
CurveByPoints curve = CurveByPoints.Create(points);
// 将曲线添加到文档中
using (Transaction trans = new Transaction(doc))
{
trans.Start("Create Curve By Points");
doc.Create.NewModelCurve(curve, SketchPlane.Create(doc, Plane.CreateByNormalAndOrigin(XYZ.BasisZ, XYZ.Zero)));
trans.Commit();
}
}
