It will not fix existing drawing, but at least you will not having a bigger problem.You can set it in AutoCAD options, Drafting Tab. By default, objects have a zero elevation. Absolute Cartesian (X,Y) coordinates in the form X,Y (for example, 7,4) 2. to set it every time you start AutoCAD. The objects may be distorted, lines will not join, or linetype settings do not show up. "In Options, go to the Drafting tab. I would also use DWG rather than DXF as a transfer data format. Then you can pick the end point of the lines to start your new line, and it will set the new line at elevation 0 no matter what the selected endpoint Z value is. I tested the theory by creating one line in the normal X, Y, Z plane that AutoCAD defaults to. Select Replace Z value with current elevation. Here’s how: Select All Text with Quick Select tool. If you work in 3D and want to draw in the same plane while drawing, turn this on.

When you type in the desired elevation and hit Enter, AutoCAD will automatically ask you to select next polyline. I wanted to convert it to a 2D drawing with no lines with z coordinates, so I've made "flatten" command, then set the osnapz to 1. I known FME squashes DXF contours to 2d + attribute to save memory, where as DWG maintains full 3d. Then change the ‘Text alignment Z’ value to 0. If you want to Move Text to the Elevation corresponding with the text value, such as for a Civil elevation, you can use this command. ... AutoCAD 2010 :: Elevation (Z) Out Zero Aug 6, 2012. In the bottom left is Object Snap Options. Scaling them with X and Y scale set to 1 with Z scale set to 0.00000001 will flatten anything.
