Hi Can you help me how to make 2D line with 3D line align and order in WCS 2D.? my AutoCAD File I draw in World USC(WCS)but it not in order with 2D ,That line connect wrong UCS in 3D...... How to make it in order to 2D line?

I'm not sure what you are asking.  Can you provide any further information?You want to align a 2D line with a 3D line?

Hello Sayrithy, maybe you are dealing with what is explained in the AutoCAD file here enclosed.
Please confirm.
I have the problem but not the solution.
Maybe someone around the planet can answer. If you want to have all the lines of your drawing at Z:0, then use the command FLATTEN.

First thanks everyone, let's me explain more about my problem.I have been draw for plan of 2D (Line use) but the Line it in difference level (Z Value Current Elevation).Can you help me to make the line align to Z:0 all or make it flatten line?

Hello again Sayrithy, I suppose that you are working on a file that's not entirely yours, if not you wouldn't have done these "Z lines" on your 2D drawing.
Use the command FLATTEN on it and take a 3D point of view to see if all is OK.
If the file is big it will take some time, be patient or do it in various steps.

 
Hi philippe JOSEPH thanks a lot that it work on my some file. but in this file still not working . Is that have other way to make it ?

Hello sayrithy, FLATTEN is normaly working with simple item such as lines, arc and circles but maybe it will be hard with dimensions or solids.I don't have the problem with solids as I leave them in place in 3D.If you want to flatten solids then you will have to use FLATSHOT to generate a flatten geometry ( with or without hidden lines ) and this won't destroy your solids but generate a new entity at Z = 0 if you work with UCS world in an plan view.An other way would be to open the properties pannel, select some entities and modify the Z elevation, the problem with this is that you will havz to select at one time only lines and not arcs, circles etc, then only arcs, circles and not lines, dimensions etc.

In some DWG drawings (usually non-Autodesk DWGs), the normal vector of some objects can cause problems. In these cases the utility "Reset210" might help. See:http://www.cadforum.cz/cadforum_en/rotated-ucs-when-stretching-objects-with-grip-editing-tip9916
