Examples

VBA:

Sub Example_AddSphere()
    ' This example creates a sphere in model space.
    
    Dim sphereObj As Acad3DSolid
    Dim centerPoint(0 To 2) As Double
    Dim radius As Double
    
    centerPoint(0) = 5#: centerPoint(1) = 5#: centerPoint(2) = 0#
    radius = 5#
    Set sphereObj = ThisDrawing.ModelSpace.AddSphere(centerPoint, radius)
        
     ' Change the viewing direction of the viewport
    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
