screw modifier

gday everyone

I’m after some help with the screw modifier

question 1: Can I make the sfrew wind the other way ie, left hand and right hands thread?

Question 2: Can I use it too boolean cut the spiral out off s cylinder?

I am trying to cut this spiral out of this cylinder then i want to flip it and cut it the other way making a crisscross cut.

I also want to join the ends of the spirals to make it a continuous track :slight_smile:

No Hands

Use a negative angle
Add the boolean modifier to the object you are cutting the screw out of seems to work most best

hope my edit explains what i’m trying to do
