Re: [V8i C#] Syntax for DLLImport

JensS:

[DllImport("stdmdlbltin.dll")]
public static extern int mdlSurface_project(out int surfDscrPP,
                                                                    int elDscrP,
                                                                    BIM.Point3d point1,
                                                                    BIM.Point3d point2,
                                                                    BIM.Transform3d pTransform);

Try ref instead of out.
