A
If you use rotated UCS or if you export DWG from some vertical applications (like Civil3D or ADT), some right-hand arcs may be represented with a switched normal (rotated normal vector [X,Y,Z]=[0,0,-1]). With such "backside" arcs you cannot e.g. draw perpendicular lines (PER osnap) or you may find othe problems.

To normalize such arc to the standard format (normal vector [0,0,1]), you can use the free LISP utility - Xanadu ArcNorm - for dowwnload on DL Download (load it by APPLOAD, start it by ARCNORM). This command selects all switched arcs and make their direction normal (without visual changes in the DWG file).
