Topic: Filter by Z-Value

Sounds like you need to use Joe Burke's superflatten routine.

seems like there are two threads in one here, lol 

So anyway, I think I have my LISP doing what I want with this:

Code: [Select]

(defun c:fz0(/ cSet)

(setq cSet (ssget
'((-4 . "*,*,=")
  (10 0.0 0.0 0.000)
  (-4 . "<NOT")
  (0 . "LWPOLYLINE,POLYLINE");;not polylines
  (-4 . "NOT>")
)
)
      )
 
  (if cSet
    (progn
      (princ(strcat "\n" (itoa(sslength cSet)) " found."))
      (sssetfirst nil cSet)
      ); end progn
     (princ "\nNothing found. ")
    ); end if
  (princ)
  ); end of c:fz0
So my last question is how do I now edit this so that it selects objects with z of either 0.0 or -999.0
I did try experimenting with (-4 . "<XOR") but it didn't seem to work....

This seems to work:

Code: [Select]

(setq cset (ssget "x"
  '((-4 . "<OR")
    (-4 . "*,*,=")
    (10 0.0 0.0 0.000)
    (-4 . "*,*,=")
    (10 0.0 0.0 -999.0)
    (-4 . "OR>")
    (-4 . "<NOT")
    (0 . "LWPOLYLINE,POLYLINE")
    ;;not polylines
    (-4 . "NOT>")
   )
   )
)

d-unit
could you post a sample DWG for testing?

There are 4 Mtext and 3 leader objects that are at Z=2700 that will not go to Z=0 using the attached code.
Thanks in advance CAB.

(Also, it looks like there is a block that has an attribute on a different Z value as well.  I haven't looked into that one yet.)

See link in Ron's post or the old Flatten worked too.
Maybe because it has a dictionary attached, not sure but don't have time to investigate at the moment.

Thanks for the link Ron!  Worked like a charm.  I tried the express tools flatten, but it converted leaders into Plines and Mtext into Text (and got rid of my fields!).  Superflatten keeps the objects the same...one of these days I'll have to dissect that program so I can learn from it.

This seems to work:
