I have a drawing in which "normal Z" of the center of circles is -1. Thats why the coordinates became negative in ASCII dxf format text file. I want to change the normal Z to 1.
Note: There difference between Normal Z and Center Z. We get normal Z for only circles.
I was able o change the the Z coordinate to 0 but the normal Z is still -1.
Format is like Normal X=0 Normal Y=0 and Normal Z=-1
I did elevating Z to 0. Tried changing UCS to world but not helping/ I have attached the sample drawing for reference. Any auotlisp will also help!
