hi. how do you get the right coordinates when the ucs is not set to world. z axis is rotated at an angle?
Dim v3d As Geometry.Vector3d = curv.GetFirstDerivative(bRes.PickedPoint)
gives an error -> bRes.PickedPoint -> if the z axis is rotated at an angle. thanks...
i believe the answer has something to do with transformby method. PickedPoint.TransformBy but I dont know how to define the argument for the TransformBy function. pls correct me if im mistaken here. Thanks...
