Nevermind, I guess I found a way to do it, but it was kind of not straight forward. I added a relation to the mix and made the line and the axes colinear.
Let me rephrase my problem. I don't know how to 3d sketch so that the line specifically follows the reference axes. under the parameters, it doesnt really say anything about the new reference axes.
This answer is exactly what I needed. I only have one problem. I dont know how to sketch along a user created axes. It disappears when I go into sketch mode.
