( local deg = 46 /* defines

(
	local deg = 46  /* defines the max angleDifferential to straight up for deletion */
 
	--------------------------------------------------------------------------
	--------------------------------------------------------------------------
 
	with undo on
	(
		for Obj in selection as array where isValidNode Obj AND superclassOf Obj == geometryClass do
		(
			convertToPoly Obj
 
			polyop.deleteFaces Obj  ((for f = 1 to Obj.numFaces collect if acos (dot (polyOp.getFaceNormal Obj f node:Obj) [-1,0,0]) < deg then f else 1) as bitArray) delIsoVerts:true
		)
	)
	completeRedraw()
)--END local

don't have access to max atm but that should do it

It is not working on a box...as the script is based on angle of normals!! Is there any way to delete the faces purely based on the location of there normals (not angle)?? So that I can delete all faces whose normals are situated in -X axis (global)?
