Autocad R14 - adjusting z values of objects?

Hello,

i am working in a plan file that contains lines with different z-axis
values. for instance, one endpoint of a line has a z value of zero,
while the other endpoint has a z value of 100. i need to know the
command where you can select ALL objects in the file at the same time
and adjust the z values for all of them at once...

thanks in advance for your help...

 

HiHo;
There is a progrem called "flatten.lsp" that sets all z coordinates to zero.
By changing this line " nplist (reverse (append '(0.0) (cdr (reverse
oplist))))"
to " nplist (reverse (append '(YOUR ELEVATION) (cdr (reverse oplist))))"
you can change the objects to a elevation of your choice.

 

Save the following in a file called "flat.lsp" in you acad path, then
appload the lisp file and issue the command "flat".
It will put everything to z=0, blocks with Z, and some surfaces of solids,
and edges of things with thickness. Make sure everything is unlocked and
visible.

(defun C:FLAT ()
(command "_.move" "_all" "" '(0 0 1e99) ""
"_.move" "_p" "" '(0 0 -1e99) "")
(princ)
)

Yes, you can. Just select the lines, and then open the properties
window (hmm... I don't know for sure that this is a verison 14 option)
Then just enter 0 for the Z-Value field.

Certain objects will not accept this (such as 3D solids), so to
allow the properties window to show it to you, you must only select
the allowed entities. If the Z-Value field doesn't show up, you have
something in your selection set that can't have a z-value set for it.

Also, another trick is to type
MOVE ALL 0,0,0 0,0,1e99
MOVE ALL 0,0,0 -0,0,1e99

This moves objects as high as AutoCAD will allow and then back to zero
elevation, thus rounding off any Z-value to zero. This is what the
mentioned LISP routine does.

I meant to say:

It will put everything to z=0, >>EXCEPT<< blocks with Z in them, and some
surfaces of solids,
and edges of things with thickness.
