I have a cylinder plus a square helix made from running a square around a rail. (Helix is planar capped.)
I can take a box and perform a Boolean Subtraction on both…
… and it works perfectly.
I then move the square helix down into the cylinder
to attempt a subtraction of the helix from the cylinder concentrically with the outer surface.
If I move the square helix up or down concentric with the cylinder it still fails.
If I scale up the edges of the square helix outside the cylinder diameter …
The subtraction still fails.
Now, if I break concentricity… And perform the subtraction … it works fine.
Appreciate any thoughts about why I am not getting the subtraction when the solids are concentric?.
Thanks! Best regards,
