You use AutoCAD LT® software and have been sent a three-dimensional (3D) drawing. This means that parts of the drawing have Z coordinate values in addition to the usual X and Y coordinate values. You want to flatten the drawing so that it only has X and Y coordinate values.
Solution
To flatten the Z axis values, you can either use a procedure or one of two macros that can be assigned to a toolbar button to do the same thing.
Important
Be absolutely certain to move in the Z direction, otherwise you'll destroy the whole drawing (you can use UNDO to undo accidental changes unless you save, exit, and restart the software).
Make a backup copy of the drawing before implementing this solution.
Use a macro
These two macros move objects to a theoretical maximum distance on the Z axis and then back to the starting point. This procedure takes advantage of the way the software is designed to flatten all Z axis values to zero.
Macro to flatten a selected object:
[FlattenSel]^C^C_UCS;;_select \_move _p;;0,0,1e99;;_move _p;;0,0,-1e99;;
Macro to flatten all objects in a drawing (in the current space):
[FlattenAll]^C^C_UCS;;_move _all;;0,0,1e99;;_move _all;;0,0,-1e99;;
Use a procedure
Here is the procedure you can use at the command line:
Move
<< select all >>
0,0,1e99
Move
P(revious)
0,0,-1e99
