hi chronos, after you measure the tool at the senzor, go tool data menu \ select tool \ tool edit \ from here i am lost, because i am not near a machine with cas, but you have to look for tool&holder settings, and search a button labeled "autoset" ( i don't remember exactly the button label ), but it should position your virtual tool in accordance with your real offset
however, i don't work with the 3d models, because it requires too much setting time
what i do, is simple measure the tools, and run the program : of course, this involves that code had been checked allready for potential colisions, or next step is checking for colisions while the program is runing / kindly
