Need help with threading nuts

I'm still relatively new to CAD, so please take it easy on me :)

I am trying to make a long hollow cylinder which is internally threaded, so that I can screw in another piece. I tried following the steps in this video but am still having trouble:


Specifically, when I sketch the triangular tooth, I cannot get it normal to the helix. What I am missing? The sketch for the cylinder is on the top plane. It is extruded perpendicular to the top plane. I have tried sketching the tooth on the front and right planes without success.

My project is here: https://cad.onshape.com/documents/d60ba5a2d4967a56c0268417/w/3959d4f30bffb543413aaf3f/e/329f58c3f976acafe6b497c9

Thanks in advance!

    Actually I think I found the answer. I had to create my own curve point plane and sketch my tooth on that!
