I just finished reading the whole thread - well... there is no real answer in the end :-(
How accurate do you need this to be? (how many points typically?) Is this used to draw dashes or simply positioning few objects? B. 2006/5/10, Bernard Poulin <[EMAIL PROTECTED]>:
yes, this is indeed a duplicate! If you are really hoping to find help - you should always search the archives...
