You can create those sharp cuts and extensions in the flat state using Unbend, make the changes, and then Bend back. You may need to suppress the Bend back operation to see those cuts as lines. Since only straight cuts across bends can be straight lines I expect that all other cuts use splines to avoid lengthy computation to determine if lines, arcs, conics, or splines are to be used.

From what i seen in your pictures, it looks like the angled transitions were created using a cut that is normal to the "Driving surface".

If this is the case you will need to redefine the cut as normal to surface.

The spline is being generated because you have an angle through a bend.

Keep your bends straight sided and see if that helps.
