how to import Spline type

[wuzhou]

Hello,

I am trying to import AutoCAD drawings using CADImport.NET, i found your product is very good in many ways. But also i found that some elements are quite difficult to be imported without some proper examples. For example, do you have an example to show how to import a spline shape? Also, sometimes the curve is plotted as polyline in AutoCAD drawing, how can i get this element in correctly? (i am using VB2005)

Thanks.
