I am working on a Cad file, the map of a city. The lines, polylines, hatch, splines, blocks, text, they all have different Z coordiantes.
To bring them all to level zero, I tried the following:
- Flatten objects
- Move objects to 0,0,1e99 and then 0,0,-1e99
Neither worked. I also tried selecting everything and changing property to set Z coordinate to 0, but it's apparently not possible as they are different object types!
If anyone has tried and solved this problem, please help me!

Load flat.lsp using the APPLOAD command in AutoCAD. Once it is loaded type the word flat at the command line to start the routine.

I have found a method on a french site "top quiz des galčres autocad" and it works like this :
move all the objects from 0,0 to 0,0,1E99 ( "E" not "e" )
then move all the objects from 0,0,1E99 to 0,0,0
I use it to work on topografic files with ground curves at different levels and it works fine ( it solves the problems of chamfers betwwen lines etc... )

I would think the "e" would work either way. Why would it be case sensitive?

Different methods to flatten entities with varying Z-coordinates to Z=0.Via a macro (Source: CADforum)
Add 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; the displayed format is to
be used for old MNU/MNS files - if you add the macro through the new Do not use it on 3D solids as it may distort them. (original concept by Randy Richardson) * * * * * * * * * * Using FLATTEN.LSP as originally written by Mark Middlebrook with improvements by Vladmir Livshiz. FLATTEN.LSP sets the Z-coordinates of these types of objects to 0 ;;; in the World Coordinate System: ;;; "3DFACE" "ARC" "ATTDEF" "CIRCLE" "DIMENSION" ;;; "ELLIPSE" "HATCH" "INSERT" "LINE" "LWPOLYLINE" ;;; "MTEXT" "POINT" "POLYLINE" "SOLID" "TEXT" [add link to Flatten.lsp here] * * * * * * * * * * In full AutoCAD one can go to Express Tools and use the FLATTEN OBJECTS command which can be found in the Modify section. * * * * * * * * * * Some users have suggested using the FLATSHOT command available in full AutoCAD. * * * * * * * * * * And an “oldie but goodie” from “back in the day” is the CHANGE command and its ELEVATION option. ------------- "Humans have a strength that cannot be measured.
