Hello everyone,
I'm trying to use the "rotate" function obtained from the "plottool" collection downloaded from this community some time ago. I would like to know why the "rotatemesh" function is marked in red as it is evident from the following figure, while the function "rotate" which utilizes it, doesn't give error?:

Because rotate operates upon the whole 3D mesh (3x(BoundxBound)) whereas rotatemesh only operates upon an individual mesh (eg, x-y or z-x (BoundxBound)).  Try vectorizing the rotatemesh expression in Frotate.
