You can use vtran command. You have to define new local coordinate systems and transfer your object to it.
For example
! define coordinates of the rotation point
xrot=0.5
yrot=0.5
zrot=0.5
! define rotation angle
xang=15
yang=0
zang=0
local,11,,xrot,yrot,zrot
local,12,,xrot,yrot,zrot,xang,yang,zang
csys,11
vtran,12,1,,,,,1
