I am trying to create an auger with a triangular fin. The fin has to stay normal to the axis. When I try to create a sweep of the fin, the profile tilts as it moves along the spiral. I cannot get rid of this tilt that is produced with the sweeping feature. The final aim is to produce a variable pitched auger that is used for mixing of a powder.
Can anybody please help me to understand why this is happening and how I can get rid of it.
Attached is the picture of the problem. I've added the part as well.
Thanks in advance!
