bpjewell Posted January 21, 2006 Share Posted January 21, 2006 Hi, I have a quick question which I hope there is an answer to, it's a problem that has been annoying me for a long time! The problem is that I am working with OS maps which for some reason are drawn with lines which are scattered all over the Z axis. Each line is in one plane on the Z axis (i.e. both ends of each line have the same Z co-ordinates) but almost every line has a different Z co-ordinate! This causes me majot headaches when I am trying to locate scheme drawings on maps or use objects from these maps in drawings. I know that I can draw over the maps using polylines and get my lines in one plane that way but it is far too time consuming! Is there a quick way to move all the lines to zero on the Z axis without affecting their X and Y co-ordinates? If anyone can help I would be extremely happy! I'm using AutoCAD 2005 by the way.

dbroada Posted January 21, 2006 Share Posted January 21, 2006 you can use "quick select" (right clip menu) to select all line. Then go to properties (another right click) and type 0 in the z co-ord box. Quote Link to comment Share on other sites More sharing options...

CarlB Posted January 21, 2006 Share Posted January 21, 2006 For lines that have endpoints with differing z values (apparently not your case) that method wouldn't work. The Express Tools "flatten" command will work on most every object to change all z values to 0. Quote Link to comment Share on other sites More sharing options...
loocifur Posted September 24, 2010 Share Posted September 24, 2010 I have used Flatten..Sleected all,but doesnt work..Any other solution? Quote Link to comment Share on other sites More sharing options...
ReMark Posted September 24, 2010 Share Posted September 24, 2010 There's always the old standby use of the CHANGE command. The option you want to use is called ELEVATION. Set it to zero. Quote Link to comment Share on other sites More sharing options...
