Hi i hope you can help.I need to flatten objects to z=0, i am using Autocad LT 2000iThe instructions say to make a macro and add it to my toolbar, I have no idea how to do this, This is the message givenAdd a new macro
(icon) to your toolbar - in fact two single-line macros (tool buttons)
- one for selected objects and the second for all objects:
[FlattenSel]^C^C_UCS;;_select \_move _p;;0,0,1e99;;_move _p;;0,0,-1e99;;[FlattenAll]^C^C_UCS;;_move _all;;0,0,1e99;;_move _all;;0,0,-1e99;;_chprop;_all;;_thickness;0;;
(keep the macro text on a single line)
Do not use it on 3D solids as it may distort them.

(original concept by Randy Richardson)Thanks in advance for any helpChristopher

There are 2 ways to flatten objects
 
1. Select all objects: Make the "Z-elevation as 0" i.e if object is line or arc make Z-coordinates as 0 if it is polyline make elevation as 0
 
2. Export the drawing to .dxf format  it would make all object flatten automatically. If you are not able ot export save the drawing in .dxf format
