Point Creation COM Style

Here is an example on how to create a point in Civil 3D using COM. To duplicate this feat, download the Civil 3D Reminders Pack. Right click on a folder, maybe the Points perhaps? Then choose create new class. Give the class a classy name. Then paste the code below into the class, replacing all of the items. Change the class name to match the file name.

<Assembly: CommandClass(GetType(PointCreation))> 

Public Class PointCreation

    <CommandMethod("CreatePointExample")> _
    Public Sub HelloWorld()

        Dim oCivil As New AeccAppConnection

        Dim newPoint As AeccPoint
        Dim dLocation(0 To 2) As Double
        dLocation(0) = 0
        dLocation(1) = 0
        dLocation(2) = 0
        newPoint = oCivil.AeccDoc.Points.Add(dLocation)

    End Sub

End Class

If you don’t want to use the Civil 3D Reminders Pack make sure to download the Quux free edition and use a reference to it to get the AeccAppConnection to make it easier to get the Civil 3D document.
