Problem with a spiral that shifts

3D Design Volume Model

Hello everyone, I am doing a sweep from a spiral.

Can someone explain to me why when I shift the starting angle, the sweep starts a turn below. (In red)

 

Thank you in advance.

Hello

 

Isn't it the start of the sweep that needs to be changed by setting a value close to zero, for example?

Hello

I advise you to always make your scan sketch coincide with the starting point of your propeller. I just tested on your file, by doing this you are sure of your starting point.

Thank you both.

@ coyote yes it functions but what is the purpose of the offset then and in addition it starts exactly one turn below.

I had taken your method and yes it works.

I don't understand the history of the discrepancy. What is the difference?

In the propeller function you can angularly shift the start.

Yes, okay, but I don't see the connection.

The spiral should always be made first and then the profile to be done scanned on the starting point of this spiral. So if we shift the angle and the plane is positioned on the starting point, everything will follow correctly.
