Does anyone know how to sketch a logarithmic/golden spiral in Shapr3D? I’ve checked the online documentation and searched the forums and cannot find anything. Thoughts?

Be well. Stay safe.
I would think you would need scripting capabilities for that.
Hi. I use the 90 degree approximation of the “golden spiral” in handrail making.
Most people drawing these use an approximation. But as @Oregonerd says, the genuine version would at least require a formula input of some kind.
There have been a few posts on the subject in the past, but mostly using a 180° approximation.
Let me know if you’re needing help with the 90° version.
Guidance for drawing the 90 degree approximation would be incredibly welcome. Thank you!
Start with a box 1 unit (inch, cm, mi, etc). Lock it’s sides and location make a box 1.61 times that next to and lock it also. Repeat that multiple times. Then draw arcs in the appropriate corners of each box whose radius is = to the side of that box….

Try 1.618 as your multiplier.
Thank you for the link and guidance! You all are the best!

I think my solution is closer to the Fibonacci, less Golden ratio.
Helping you was a fun rabbit hole for me!
This was quite fun for me as well! Thank you so very much!
