GetOrientation 方法 (ActiveX)
获取指定的角度。忽略 ANGBASE 系统变量的设置。 支持的平台:仅限 Windows 签名VBA: RetVal = object.GetOrientation([Point [, Prompt]])
返回值 (RetVal)类型:双 指定的角度。 言论AutoCAD 暂停用户输入角度,并将返回值设置为所选角度的值。Point 参数指定 WCS 中的角度基点。Prompt 参数指定 AutoCAD 在暂停之前显示的字符串。“点”和“提示”都是可选的。 AutoCAD 用户可以通过在当前角度单位格式中输入数字来指定角度。用户还可以通过在图形屏幕上指定两个 2D 位置来指定角度。AutoCAD 从第一个点到当前十字准线位置绘制一条橡皮筋线,以帮助用户可视化角度。如果提供了“点”参数,AutoCAD 将使用此值作为两个点中的第一个点。角度在 WCS 的 XY 平面上测量(此方法忽略 Point 的 Z 场)。角度增加的方向始终是逆时针方向。 无论使用何种方法指定角度,始终将返回值设置为以弧度表示的值。GetOrientation 此方法与该方法类似,但它忽略了存储在 ANGBASE 系统变量中的角度 0 的当前方向。使用的 0 角始终向右:“东”或“三点钟”。GetAngleGetOrientation 如果返回的是关键字而不是角度,AutoCAD 将生成错误消息“用户输入关键字”。使用该方法从返回值中获取关键字。GetInput 例子VBA: Sub Example_GetOrientation()
' This example uses the GetOrientation method to demonstrate three different ways to retrieve
' an orientation from the user.
AppActivate ThisDrawing.Application.Caption
Dim retOrientation As Double
' Return the Orientation in radians with a prompt
retOrientation = ThisDrawing.Utility.GetOrientation(, "Enter an Orientation: ")
MsgBox "The Orientation entered was " & retOrientation & vbCrLf & _
"(Enter the next value without prompting.)", , "GetOrientation Example"
' Return the Orientation in radians without any prompt
retOrientation = ThisDrawing.Utility.GetOrientation()
MsgBox "The Orientation entered was " & retOrientation, , "GetOrientation Example"
' Return the Orientation in radians with a prompt and an Orientation base point
Dim basePnt(0 To 2) As Double
basePnt(0) = 2#: basePnt(1) = 2#: basePnt(2) = 0#
retOrientation = ThisDrawing.Utility.GetOrientation(basePnt, "Enter an Orientation: ")
MsgBox "The Orientation entered was " & retOrientation, , "GetOrientation Example"
End Sub
