Sorry for double posting... The method with "if not flag" is a bit
arkward, because assignObj isn't the only problem. "rotateObj(s, 90)"
would rotate the object 180 degrees instead of 90; when defining the
relation between several objects some equations may became redundant (my
script is rather complex and I'm not sure why some of the equations
cause trouble).
