Create New Layer

When inserting objects into AutoCad its useful to set different layer to keep it all organised. The code below shows how to create a new layer  


Function CreateLayer(ByVal namelayer As String, ByVal R, G, B As Double)

'*** Code from VisibleVisual.com ********

On Error Resume Next

Dim color As AcadAcCmColor
Dim newlayer As AcadLayer

'Select Layer or if not exists create a new layer
Set newlayer = ThisDrawing.Layers.Add(namelayer)
If Err > 0 Then
Set newlayer = ThisDrawing.Layers.Item(namelayer)
End If

'Set AutoCAD Color Objects
If Left(AutoCAD.Application.ActiveDocument.GetVariable("acadver"), 2) = "16" Then
Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.16")
ElseIf Left(AutoCAD.Application.ActiveDocument.GetVariable("acadver"), 2) = "17" Then
Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.17")
MsgBox "Wrong Autocad version fro this function"
Exit Function
End If

'R,B,G stands for Red, Green, Blue value
Call color.SetRGB(R, G, B)

'Create a Layer and make it the active layer
newlayer.TrueColor = color
ThisDrawing.ActiveLayer = newlayer

End Function
