create a box on every face normal center from selected object

This can be achieved in different ways. This is one of them:

(
	objToCreate = Teapot()
	
	delSurfaceObj = false
	surfaceObj = selection[1]
	if classOf surfaceObj != Editable_Poly do
	(
		surfaceObj = convertToPoly (copy surfaceObj)	
		delSurfaceObj = true
	)
	facesCnt = polyop.getNumFaces surfaceObj	
	for f = 1 to facesCnt do
	(
		obj = instance objToCreate
		obj.pos = polyop.getSafeFaceCenter surfaceObj f
		obj.dir = polyop.getFaceNormal surfaceObj f
	)	
	delete objToCreate
	if delSurfaceObj == true do delete surfaceObj
)
