Is there a lisp that works like SetPt command in Rhino ?

[ozancem_cicek]

I've been strugling with the floor plan drawing that is drawn in x, y and z axis. But all drawings has to be aligned only and only two (x and y) axis. There is a command called SetPt in Rhino perfecty aligns all lines in specific axis. So is there a way to do the same on AutoCAD ?

FLATTEN.

And to prevent Object Snap from including the Z coordinate in locations you Osnap to when drawing new objects, set the OSNAPZ System Variable to 1.
