[BuyAGS400]

Does anybody else have problems with broken lines in flat pattern translated
files?
Often when using provided electronic data to make customer parts the lines
adjacent to scallops and radii dont meet by a few tenths and will not chain.
To drive a tool around perimeter a lot of time is used to connect the lines.  
Does anybody know of a software or method that will make this process less of
a task?

any input would be greatly appreiatiated
