I am using Civil 3d2015 and need to calculate the location of a point on a featureline so that I can add an elevation point. I found the COM Get2dDistanceAtPoint() function, but I am having trouble getting it to work.
Function Get2dDistanceAtPoint(varPoint As Object) As Double
Member of Autodesk.AECC.Interop.Land.IAeccLandFeatureLine
I have tried passing it a 2d and 3d point with no success. Does anyone know what this is looking for and more importantly, how do you go about finding what is needed if a function or method does not use a specific type?
