Dear colleagues

I am using AutoCAD R14 to design a mask set. As the set is a particularly
complex one, this makes it difficult to detect and correct errors. The set
has been sent to our mask makers, who have detected a number of 'open
polyline objects' within the design. Unfortunately, the mask makers cannot
specify where the open polylines are within the set. It should be noted that
the ebeam cannot write open polyline objects of zero width when writing the
masks.

I have been told that there is a way within AutoCAD to select and display
open polyline objects, but I am not too sure how to do this. There is an
option for selecting polylines but it seems that there is no option for
selecting open ones from closed ones. If anyone has any suggestions - please
let me know ?


Many thanks
