Inventor Patterning Hexagon Shape Twist Rotated 9°

Im ok with patterning but had a question come up recently that im not 100% sure about. We have a walkway that is a hexagon shape as you walk through it. its 300mm deep x 2400mm inscribed height. we need to pattern it 20 times in 1 direction (actually, preferred on a spline but linear is ok) but for each pattern element, it needs to be rotated 9 degrees. What is the best approach for this?

Thanks

Nacho

Hi Nacho,

If I understand correctly what you are trying to achieve there is no direct/simple way to do this. I see a brute-force way to do it with feature pattern: create a pattern of solids (you will have 20 solids) then use direct edit to rotate each one. It’s not too painful if you only need to do it one time – it took me less than five minutes to get the attached result.

Hope this helps....

Thanks for the reply. Was thinking more like this but your idea is perfectly reasonable. shame that patterning cannot achieve it but this method works 🙂

Cheers

Oooh – that makes more sense. Here’s a method to get there (attached). I created a swept surface with a 180 deg twist, and used that to align the occurrences in a Sketch Based pattern.
