Autodesk.Revit.DB.PlanViewDirection

简介

Autodesk.Revit.DB.PlanViewDirection是一种表示Revit平面视图方向的Class，该方向可以是平行于X、Y或Z轴方向的平面视图。

构造函数

public PlanViewDirection(XYZ forwardDirection, XYZ upDirection)

• forwardDirection: XYZ类型，平面视图正方向的向量
• upDirection: XYZ类型，平面视图向上的向量

属性

UpDirection

public XYZ UpDirection { get; }

获取平面视图向上方向的向量。

ForwardDirection

public XYZ ForwardDirection { get; }

获取平面视图正方向的向量。

方法

IsParallelTo(PlanViewDirection otherDirection)

public bool IsParallelTo(PlanViewDirection otherDirection)

• otherDirection: PlanViewDirection类型，需要比较的PlanViewDirection对象

返回值：比较的两个PlanViewDirection对象是否平行。

IsPerpendicularTo(PlanViewDirection otherDirection)

public bool IsPerpendicularTo(PlanViewDirection otherDirection)

• otherDirection: PlanViewDirection类型，需要比较的PlanViewDirection对象

返回值：比较的两个PlanViewDirection对象是否垂直。

示例

构造函数

//创建向上和正方向均为Z轴的平面视图
PlanViewDirection planViewDirection = new PlanViewDirection(new XYZ(0, 0, 1), new XYZ(0, 0, 1));

属性

//获取平面视图的正方向
XYZ forwardDirection = planViewDirection.ForwardDirection;

//获取平面视图的向上方向
XYZ upDirection = planViewDirection.UpDirection;

//输出结果
Debug.Print("ForwardDirection: ({0}, {1}, {2})", forwardDirection.X, forwardDirection.Y, forwardDirection.Z);
Debug.Print("UpDirection: ({0}, {1}, {2})", upDirection.X, upDirection.Y, upDirection.Z);

方法

//创建两个平行的平面视图方向对象
PlanViewDirection planViewDirection1 = new PlanViewDirection(new XYZ(1, 0, 0), new XYZ(0, 0, 1));
PlanViewDirection planViewDirection2 = new PlanViewDirection(new XYZ(1, 0, 0), new XYZ(0, 0, 1));

//创建两个垂直的平面视图方向对象
PlanViewDirection planViewDirection3 = new PlanViewDirection(new XYZ(1, 0, 0), new XYZ(0, 0, 1));
PlanViewDirection planViewDirection4 = new PlanViewDirection(new XYZ(0, 0, 1), new XYZ(0, 1, 0));

//判断两个PlanViewDirection对象是否平行
if (planViewDirection1.IsParallelTo(planViewDirection2))
{
    Debug.Print("PlanViewDirection1 is parallel to PlanViewDirection2.");
}
else
{
    Debug.Print("PlanViewDirection1 is not parallel to PlanViewDirection2.");
}

//判断两个PlanViewDirection对象是否垂直
if (planViewDirection3.IsPerpendicularTo(planViewDirection4))
{
    Debug.Print("PlanViewDirection3 is perpendicular to PlanViewDirection4.");
}
else
{
    Debug.Print("PlanViewDirection3 is not perpendicular to PlanViewDirection4.");
}
