catia vba 测量距离的程序

在CATIA VBA (Computer-Aided Three-dimensional Interactive Application Visual Basic Automation) 中，测量距离通常涉及到对几何体的操作和坐标系的处理。下面是一个简单的示例，展示如何编写一个基本的VBA脚本来测量两点之间的直线距离：

Sub MeasureDistance()
    Dim doc As CATIAApplication
    Dim partDoc As CATPartDocument
    Dim feature1 As CATFeature
    Dim point1 As CATPoint3D
    Dim point2 As CATPoint3D
    Dim distance As Double

    ' 创建实例
    Set doc = CATIA.Documents.Add
    Set partDoc = doc.ActiveDocument
    
    ' 假设你已经有了两个特征点，分别存储在point1和point2变量中
    ' 如果需要获取，你可以通过特征的几何属性获得它们
    ' point1.X = 函数A.X, point1.Y = 函数A.Y, point1.Z = 函数A.Z (替换函数A为你的特征名)

    ' 计算两点之间的距离
    Set feature1 = partDoc.Features.CreateGeometryElementByTwoPoints(point1, point2)
    distance = feature1.Length

    ' 输出结果
    Debug.Print "两点间的距离: ", distance, " 单位是当前模型的单位"

    ' 清理
    Set feature1 = Nothing
    Set point1 = Nothing
    Set point2 = Nothing
    Set partDoc = Nothing
    Set doc = Nothing
End Sub
