Could you explain your 'small gain'? from what I am seeing - you have to slow down to do a parabolic blend (If I understand it - it is a read-ahead buster)
There are paths (like steve.ngc) which would be able to keep the speed up if there was arc-arc, arc-line blends and you can optimize the path (depth). And yes - I know it is a lot of work. (you are doing a great job - it is very impressive how quick you got to this point) sam On 12/30/2013 11:02 AM, Robert Ellenberg wrote: > Thanks for confirming that, Sam.
