Hello!

My script aligns object to face like this:

But i need to get this:

there is a code i used:

faces = (polyOp.getFaceSelection $Box001) as array
face = faces[1]
theMatrix = matrixFromNormal(polyOp.getFaceNormal $Box001 face)
theMatrix.row4 = polyOp.getFaceCenter $Box001 face
$object.transform = theMatrix

Help me, friends :)

thank you!
second one does it right, but it too complicated for me to understand
i write simple script that creates and aligns helper grid on selected face and i can't rotate it right way. So can you please fix my code if you know how

The best way is to try to learn something from the code that works for you.
But(not the best solution):

(
	tmpMesh = snapShotAsMesh $Box001
	faces = (getFaceSelection tmpMesh) as array
	face = faces[1]
	faceNormal = getFaceNormal tmpMesh face
	faceCenter = meshop.getFaceCenter tmpMesh face
 
	vv = getFace tmpMesh face
	dir = normalize ((getVert tmpMesh vv[2]) - (getVert tmpMesh vv[1]))
	side = normalize (cross dir faceNormal)
	front = normalize (cross faceNormal side)
	theMatrix = matrix3 front side faceNormal faceCenter
	delete tmpMesh
 
	$Box002.transform = theMatrix	
)
