Rotate Multiple Objects Around a Common Center

[experimentaldJ]

Rotating multiple objects around a common center inside of 3ds Max is easy. Select everything, rotate.

How do you accomplish this in maxscript?

I've figured out how to rotate my selected objects one at a time around the selection center, but that is not the same as rotating them together. The selection center moves after rotating one object so the rest are rotated around a new selection center.

see the MXS help about

The about <center_spec> context is the MAXScript equivalent of the rotate/scale transform center list on the main 3ds Max toolbar.

delete objects
--seed 0
for k=1 to 5 do (teapot radius:(random 10 60) pos:(random -[100,100,100] [100,100,100]))
	
center = random -[100,100,100] [100,100,100]
point pos:center wirecolor:green
	
rotate objects (eulerangles 0 0 45) about center

Sorry I should have been more clear. I need to rotate all objects around the selection center. I can't find anything on getting the "center" from "selection".

rotate selection (eulerangles 0 0 45) about selection

did you read the help?

or about selection bounding box center:

rotate selection (eulerangles 0 0 90) about (selection.center)

[experimentaldJ]

Neither of those work...

if it doesn't work, it means you're doing something wrong...

The correct line is:

about (selection.center) rotate selection (eulerangles 0 0 90)

c'mon ... what's the difference? 😉
