Multi Item Elevation/Z change?

[Anonymous]

I have a drawing that as I was working in & I copied lines, dim's, etc that were at different elevations or Z coordinates to use in new items. Don't know how everything was at different locations in a 2D drawing? File came from another firm.

The properties window defaults to no change options for elevation or Z when I choose 'all' the items at once. I started changing them one by one but that will take me till Xmas.I need everything at "0" because my work will go to a 2d table CNC.

Is there a way/command to set everything in the drawing to "0" elevation & "0" Z? Please say yes!!

Using autodesk 2017

First use INSUNITS  then 0

Command FLATTEN use No

then use OSNAPZ set to 1

Thanks, tried Flatten & Change,  and still have objects all over the place in the Z axis. Or everything is still at multiple elevations? Personally, logic precludes me from seeing a difference between "elevation" & "Z", they are the same.

Don't have the time to review on how to write a macro. I can more than likely redraw the whole thing before that. You'd think if a CAD site has that, Autodesk would include it in the menu choices? 

Thank you very much for the links and your help.

Care to share the DWG file, even if you strip it down to the objects you say still have a non-zero elevation?

Were there any messages from FLATTEN?  If you have, for example, Blocks containing elements with non-zero Z coordinates, and defined to not allow Exploding, Flatten won't work on them.  But it at least tells you that it couldn't Explode them.

This solved it for me! Thank you! Worked perfectly.
