Script to rotate objects 90 degrees around their center

Scripting
4

Try this one.
It will enable you to rotate objects left and right by 90 degrees around z,y,x axis with following aliases:
‘lz’ - left 90 degrees around z axis, ‘rz’ - right 90 degrees around z axis, ‘ly’ - left 90 degrees around y axis, ‘ry’ - right 90 degrees around y axis, ‘lx’ - left 90 degrees around x axis, ‘rx’ - right 90 degrees around x axis

import rhinoscriptsyntax as rs

def rotateObject(_id):
    if _id:
        if rs.IsCurve(_id) and rs.IsCurveClosed(_id):
            centroid = rs.CurveAreaCentroid(_id)[0]
        elif rs.IsCurve(_id) and not rs.IsCurveClosed(_id):
            d = rs.CurveDomain(_id)
            centroid = rs.EvaluateCurve(_id, (d[0]+d[1])/2)
        elif rs.IsSurface(_id) or rs.IsPolysurface(_id):
            centroid = rs.SurfaceAreaCentroid(_id)[0]
        elif rs.IsMesh(_id):
            centroid = rs.MeshAreaCentroid(_id)
        else:
            print "Something is wrong with your geometry"
            return

        directionAxis = rs.GetString("Choose rotation direction and axis", "lz", ["lz","rz","ly","ry", "lx", "rx"])
        if directionAxis == "lz":
            rs.RotateObject(_id, centroid, 90, [0,0,1])
        elif directionAxis == "rz":
            rs.RotateObject(_id, centroid, -90, [0,0,1])
        elif directionAxis == "ry":
            rs.RotateObject(_id, centroid, 90, [0,1,0])
        elif directionAxis == "ly":
            rs.RotateObject(_id, centroid, -90, [0,1,0])
        elif directionAxis == "lx":
            rs.RotateObject(_id, centroid, 90, [1,0,0])
        elif directionAxis == "rx":
            rs.RotateObject(_id, centroid, -90, [1,0,0])
        else:
            print "You typed an unsupported rotation"
            return
    else:
        print "You did not pick anything"
        return

id = rs.GetObject("Pick up the object you wish to rotate", preselect=True)
rotateObject(id)

By the way, did not know about the BoxEdit command.
Thanks Mitch.
