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.

INTOOLPATHY OPERATION MANAGER YOU CAN MAKE THE DIRECTION. SELECT THE GEO IN OP MANAGER USING THE POP UP MENU.

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!
