You can model twisted sections, like hexbars for decorative purposes, using the SWEPT BOSS feature.
First create a separate Profile (Hex shape) and a Path (straight line).
Select both sketches and select SWEPT BOSS feature.
Preview shows the Hex Profile swept along the Path.
Add the Twist option by selecting PROFILE TWIST and pick SPECIFY TWIST VALUE and pick REVOLUTIONS. Add 4 turns.
The preview is shown below.
Final model is shown below.
This is a great way to make twisted shapes, and even pasta. Enjoy.
