Resetting everything in Z axis to 0

[samla02]

Hi,

I have AutoCAD 2006LT.

The property file from an engineer has contours lines, but they are accurate and I need them flat on the Z azis. Other objects like retaining walls and many others are also off 0 on the Z axis.

One thing I will mention is that when I click on some of the objects and look at the properties, it says 'control point z' instead of Z and won't let me change it.

I would appreciate any help.

Using the "move up & back" method should change most objects to have a z=0. This about your only option, since using LT.

Command sequence:
MOVE <select objects, or "all'>
base pt or displacement:0,0,1e99
<hit enter for "to" so used as displacement>

(now objects are in outer space)

MOVE <enter "p" for previous selection>
base pt or displacement:0,0,-1e99
<again enter>

(now objects should have Z=0)
