Hello!

I think the simplyest way to do it is to return an array of lines (or entityes) from your function:

Function DrawLines()as line()

Dim ArOut() As line

[···]

Rerutn ArOut

End Function

But you may also return a "collection", a "list (Of line)" or another thing...

Hope this helps!

Thanx a lot!

it helped, and i created now an arraylist to return the objects:

    Public Function Drawlines() As ArrayList
        Dim ObjLijn1 As New Line
        Dim ObjLijn2 As New Line
        Dim Lijst As New ArrayList
        ObjLijn1.StartPoint = New Point3d(CenterX + F1, CenterY + Grootte / 2, 0)
        ObjLijn1.EndPoint = New Point3d(CenterX - F1, CenterY - Grootte / 2, 0)
        Lijst.Add(ObjLijn1)
        ObjLijn2.StartPoint = New Point3d(CenterX - Grootte / 2, CenterY + F1, 0)
        ObjLijn2.EndPoint = New Point3d(CenterX + Grootte / 2, CenterY - F1, 0)
        Lijst.Add(ObjLijn2)
        '---Return lijst
        Return Lijst
    End Function
