允许从浮动图纸空间视口编辑模型。

支持的平台：仅限 Windows

签名

VBA：

object.MSpace

对象

类别： 文档

此属性应用于的对象。

属性值

只读：不

类型：布尔

True：允许编辑模型。
False：不允许编辑模型。

言论

AutoCAD 在模型空间或图纸空间中运行。使用模型空间进行绘图和设计工作，并创建 2D 工程图或 3D 模型。使用图纸空间创建图形的完成布局以进行打印或打印。

注意：在使用该属性之前，必须将该属性设置为，并且该属性必须打开对象的显示控件。MSpaceActiveSpaceacPaperSpacePViewportDisplay

例子

VBA：

Sub Example_MSpace()
    ' This example creates a new paper space viewport.
    ' It then toggles the ability to edit in model space using
    ' the MSpace property.
    
    Dim pviewportObj As AcadPViewport
    Dim center(0 To 2) As Double
    Dim width As Double
    Dim height As Double
    
    ' Define the paper space viewport
    center(0) = 3: center(1) = 3: center(2) = 0
    width = 40
    height = 40
    
    ' Change from model space to paperspace
    ThisDrawing.ActiveSpace = acPaperSpace

    ' Create the paper space viewport
    Set pviewportObj = ThisDrawing.PaperSpace.AddPViewport(center, width, height)
    pviewportObj.DISPLAY True
    ThisDrawing.mspace = True
    ThisDrawing.ActivePViewport = pviewportObj
    ThisDrawing.Regen acAllViewports
    
    ' Find the current MSpace value
    MsgBox "The ability to edit model space from this PViewport is " & IIf(ThisDrawing.mspace, "on.", "off."), , "MSpace Example"
    
    ' Toggle the setting of MSpace
    ThisDrawing.mspace = False
    MsgBox "The ability to edit model space from this PViewport is now " & IIf(ThisDrawing.mspace, "on.", "off."), , "MSpace Example"

End Sub
