I'm having troubles trying to put in 0 level a draw, I' m using the flatten command but it doesn't work , I will appreciate all your help with this.

Hello jmontesmx, on what entities are you trying to do this : lines+arcs+texts+etc or real 3D solids or ... ???Check that there are no frozen layers, no Xref inside your file, etc...Eventually try the MOVE ALL described here :https://forums.autodesk.com/t5/autocad-lt-forum/moving-all-lines-to-z-0/td-p/393128And / or this :https://forums.autodesk.com/t5/autocad-forum/command-to-move-all-objects-to-same-plane/td-p/1069520You have AUtoCAD 2010 so the absolute coordinates should be : X,Y,Z and not #X,Y,Z.Please check because I don't remember after what release it was changed.P.S. For the 3D solids I recommend using the FLATSHOT command.

Upload a copy of the drawing.  Maybe someone here can figure out what might be wrong.

Thanks for your information,  I solved my problem  yesterday, the draw was made in civil cad, for that reason all the entities have diferent  Z level, I solved in this form, move all the draw to the infinite using like origin point 0,0,0 to 0,0,1e99, then move all the draw back using origin point 0,0,0 to second point 0,0,-1e99 .In that form all the draw are in Z=0.I need the draw in Z=0 because I'm doing a ilumination project with Visual Lighting software of Acuity brands Regards.

OK jmontesmx it's good to know that it worked for you.Can you confirm, if you are using relative and absolute coordinates in your files :You have AUtoCAD 2010 so the absolute coordinates should be : X,Y,Z and not #X,Y,Z.
