Extension free Helix

This is another option for making a helix with only native tools. Note I'm using the native facets of a circle to make it work, I've started with a 48seg circle. I used alt(win) to lift the face of the shape up (auto fold), up arrow works too. By starting with a solid you can use Outershell to continue making larger and larger solids. Then Radial arrays and mirroring can make very complex shapes. Note the block with the hole was a simple version for the benefit of the vid, you can make the starting block quite complex, just make sure it is a segment of a circle, not just a square.
