Have you tried creating a simple border around your fixture and then restricting it while creating the machining operation?
I think in your case, if I follow you correctly, that you would sketch a border, (I usually copy these to the restrictions folder for easy management) then when you are creating the toolpath, you would assign that sketch to be a restriction (probably inner, then edge of tool). Then your toolpath will stay clear. I haven't done much 2D stuff in Sprut but from what I can tell, they definitely didn't have 2D in the forefront of their mindset when developing the program.
