There must be an easy fix for this. I am using the split tool and I want it to split a polyline into equal parts. For some reason, it is starting in the middle of my polyline. How do I force it to start where I want it to? I am using ArcGIS v. 10.1.

I would probably use IPolyCurve.SplitAtPoint and get the paths (parts) created after the split and do your processing on those. As long as the createPart argument is true, SplitAtPoint doesn't just add a new vertex, it inserts a new part between the split point and the end of the path.

Whether this is the best approach somewhat depends on what processing you need to do however.
There is the "Proportion" tool in the advanced editing toolbar that splits polylines by distance. It requires a standard or advanced license.

Explode the polyline to ensure it is not a multi-geometry. Run Repair features on the polyline features class which may re-order the line segments. Additionally, if you need to reverse the line orientation, which flips the start and end vertices, you can select the line while editing, click the "Edit Vertices" button, right click on the line and select flip.
