Changing tool direction in a toolpath

I have made a toolpath for creating hemisphere in MASTERCAM. It is a SURFACE FINISH CONTOUR operation. I wish to change the tool movement direction in the toolpath. How do I achieve that ?

IN MASTERCAM OPERATION MANAGER SELECT GEOMETRY TO CHANGE THE DIRECTION USING THE POP UP MENU TO GET THE CHANGE MENU. HOW DO YOU DOWNLOAD GRABCAD FILES INTO MASTERCAM? EVERYTHING I TRIED MASTERCAM DOES NOT RECOGNISE GRABCAD FILES. I USED MOST USED FILES TO MAKE NC CODE PROGRAMS. I CAN HELP MORE. I USED MASTERCAM FOR MANY YEARS.

Mastercam can open many file types, although a few require a separate licence like pro-E. But you will find here that many engineers that create these models on GrabCad would be more than happy to save it in a file you need. Just have to ask. :)
also in my experience with mastercam, I prefer to request a STP format. most if not all Cad modeling software can export to STEP/STP. Best of Luck!
