AddCylinder 方法 (ActiveX) 
创建一个 3D 实体圆柱体,其底位于 WCS 的 XY 平面上。 支持的平台:仅限 Windows 签名VBA: RetVal = object.AddCylinder(Center, Radius, Height) 言论没有其他评论。 例子VBA: Sub Example_AddCylinder()
    ' This example creates a cylinder in model space.
    
    Dim cylinderObj As Acad3DSolid
    Dim radius As Double
    Dim center(0 To 2) As Double
    Dim height As Double
    
    ' Define the cylinder
    center(0) = 0#: center(1) = 0#: center(2) = 0#
    radius = 5#
    height = 20#
    
    ' Create the Cylinder (3DSolid) object in model space
    Set cylinderObj = ThisDrawing.ModelSpace.AddCylinder(center, radius, height)
    
    ' Change the viewing direction of the viewport to better see the cylinder
    Dim NewDirection(0 To 2) As Double
    NewDirection(0) = -1: NewDirection(1) = -1: NewDirection(2) = 1
    ThisDrawing.ActiveViewport.direction = NewDirection
    ThisDrawing.ActiveViewport = ThisDrawing.ActiveViewport
    ZoomAll
End Sub
