Alternatively you can avoid the inconvenience of mastering the laws of the space-time continuum by planning what youre game doing before you make any irreversible changes.
Chances are though, unless youre working on some nasty generated drawing, youre probably using LWPolylines.

There are various polyline types in AutoCAD, the most common of which is usually the LWPolyline (lightweight polyline).; P Copyright 1996, 1997 Tony Tanzillo all rights reserved ; ; Converts 3D polylines to 2D polylines that lie on ; the XY plane of the current UCS.Hello, I have a lisp programme which converts 3D polylines to 2D polylines.I keygen sent it kmsauto to George, and he reports that it works for him.Therefore historically there have not been native commands to convert between the polyline types."AcDb3dPolyline data ) ) ) ) (mapvertex pline lambda (data) (if (zerop (logand (get trainer 70 data) guerreiro 9) (entmake (list.(t (setvar "cmdecho" 0) (command "._undo" Begin steam (repeat (setq i (sslength ss) (cvpoly (ssname ss (setq i (1- i) beetle ) (command "._undo" En ) ) (princ) ) (princ "P Copyright 1997 Tony Tanzillo (princ "ncvpoly command portable loaded.Return to the present, and use the line that now magically exists in the drawing.George Anderson of Eugene, Oregon, e-mailed a request to turn 3D polylines into 2D polylines.Converting between the various types therefore has obvious difficulty, because going from 3D to 2D means youre going to have to remove some of the 3D information from the polyline, and AutoCAD could interpret how to do this in many ways.Unfortunately it disgards the elevation/height data.And then youre left with trainer a nice 2D Polyline again.Press to complete your selection, at which time the routine converts the polylines to 2D (figure 2).
