Creating 3D helix
Thought I had shown this, but here is a quick (once you know) way to create a 3D helix in Hexagon:-
1:- 2 cylinders just for start/end of 3D helix
2:- Create 3D path. Collapse DG when path in correct position.
3:- Increase number of points on path (I made it approx 500)
4:- Create line at one end of path
5:- Sweep line along path and add twist (I made twist 20000). Collapse DG when done.
6:- Select outer edge_loop of sweep
7:- Copy/paste which leaves new helix path (I have hidden sweep so you can see helix)
8:- add thickness to helix path (add sub_d if needed)
