"Cycle Ref. Coord. Sys" is no more?

[skyd7]

Hi, I thought "Cycle Ref. Coord. Sys" used to be an action you could assign a Hotkey to in older versions of Max? I used to use it all of the time. I can't find it in the Hotkey Actions list in 2025. Has it been renamed/dropped, or did I create one using a custom script?

-The only Coord System shortcut I could find was 'Make World'. This is useful, but not the same as being able to quickly cycle between World, View, and Local etc.

-GPT 4.o wrote me a script to create a custom key, but it should be default? In case this might prove useful, I'll drop it here:

coordSystems = #("View", "Screen", "World", "Parent", "Local", "Grid", "Working")
currentCoordSystem = getRefCoordSys()
nextIndex = (findItem coordSystems currentCoordSystem) % coordSystems.count + 1
setRefCoordSys coordSystems[nextIndex]

Thanks!

I don't see "Cycle Ref. Coord. Sys" in previous versions of 3dmax.

The GPT generated script doesn't work. Here's something that works.

macroScript CycleRefCoordSys category:"Tools" toolTip:"Cycle Ref Coord Sys"
(
local coordSystems = #(#hybrid, #screen, #world, #parent, #local, #object, #working_pivot,#local_aligned)
local currentCoordSystem = getRefCoordSys()
local nextIndex = (mod (findItem coordSystems currentCoordSystem) coordSystems.count) + 1
setRefCoordSys coordSystems[nextIndex]
)

Bad GPT?! As a non-coder this is a huge help, thank you!

Thanks for also clarifying about it in previous versions (I must've been using a custom script?).

It is nice to have the ability to toggle between states with one key press. Makes speed modeling with custom key-mapping a little more fluid I find?
