vba - 如何在 CATIA VBA 宏中获取体色？

Question

是否可以读取 CATBody 的颜色？就像是：

   For Each myBody In myPart.Bodies
             myColor = myBody.Color 
    Next

Answer 1

是的，这是可能的，但并不完全直截了当。颜色可VisProperties通过Selection. 此外，这是 Catia API 的奇怪案例之一，您需要使用后期绑定（我无法告诉您原因）

这是一个例子：

Option Explicit
Sub BodyColors()

Dim sel As Selection
Dim selected As SelectedElement
Dim vis As Variant 'VisPropertySet 'This must be variant for late binding. Otherwise you get an error.
Dim RGB(3) As Long 'or you can use an array
Dim r, g, b As Long


Dim myPart As Part
Dim myBody As Body

Set myPart = CATIA.ActiveDocument.Part
Set sel = CATIA.ActiveDocument.Selection
For Each myBody In myPart.Bodies
    sel.Clear
    sel.Add myBody
    Set vis = sel.VisProperties
    vis.GetRealColor r, g, b 'you must pass the values into the function
    Debug.Print myBody.Name & ": "; r & "," & g & "," & b
Next
sel.clear
End Sub
