Ger,
Thank you for letting me know about that because I was starting a new post processor to be use with Bobcad and wasn't aware of it. I always had the H and D on my line (perhaps too familiar with the Fanuc and Haas controlers). Anyway, a D word in the same line as the G41/G42 will allow the user to use 2 different d offsets for the same tool for semifinish and finish passes. I use that all the time where I use D 21 to semifinis a part (I add about .005 to the tool dia there) and D 1 for finish path (corect tool dia). That will be for T1 and so forth.
Merry Christmas!
