help selecting only vertical faces in scene or object

By thp777 · 2010-12-23

Description

Im using 3ds max
basically i have alot of boxes as one object and i want to select only the sides and not the top and bottom in edit poly. i also need to be able to select only the tops so either one would help then i can just use invert selection for the others i guess.
if anyone can point me towards a script or anything that can help me with creating one thx in advance.

that rlly is a simple modification you couldve done yourself quickly ;)

(
   local deg = 45  /* defines the max angleDiff to straight up for selection */
	
   local dir = 	polyop.getFaceNormal selection[1] ((polyop.getFaceSelection selection[1])as array)[1] node:selection[1]

   --------------------------------------------------------------------------
   --------------------------------------------------------------------------
 
   with undo on
   (
      for Obj in selection as array where isValidNode Obj AND superclassOf Obj == geometryClass do
      (
         polyop.setFaceSelection Obj  ((for f = 1 to Obj.numFaces collect (if acos (dot (polyOp.getFaceNormal Obj f node:Obj) dir) < deg then f else dontcollect)) as bitArray) 
      )
   )
   completeRedraw()
)--END local

Thanks ! :-)
Don't forget that nothing is really simple for me !

I tried the script and something strange : to select same orientation face u must have a "0.1" value : "0" don't select all faces that it should !....

wow

That worked perfectly.
Thank you so much.
would have taken me forever to figure that out.
Thanks again.

ohhh ! It would be great if you could make a script to select all faces oriented like the selected face modulo a value that we can specify... It would be very helpfull ! :-)
