Hello Experts!
I'm struggling with design of cutter which is made by passage of special cutter on corresponding helix (1.png).
Swept volume doesn't support this kind of bodies (concave, 2.png). I tried to use swept of section of special cutter and vector direction along the helix, but the resulting body is wrong.
I was able to prepare a sample shape, but with wrong surface (made with multiple bodies on pattern substracted from cutter). (3.png)
Images and nx files in the attachment.
Thanks for any help.
