I created a 3D datum curve and am trying to section them into different segments. The first step I need to finish is creating datum points along the 3D curve in order to use them as references in the split datum function. My problem is with the datum point creation. There is a feature called Actual Len in the Create Datum Point> On Curve menu that allows me to specify a curve length. It is using the wrong end of my curve as the starting point reference. Is there a way for me to change this?
