Surface Area Function-Could use some help.

Recommended Posts

Working on an O-inspect, I have been tasked with finding the surface area of the part in the Image. Each slot and triangle pocket are found using the Curve function 2000 points each, The ID and the OD have curves applied to them as well 2000pts each. Output all the curves using Surface area, then I subtracted all the slots/pockets/ID from the OD. My result was about 3000mm off.

I've never used this function before and looking at my report some of the slots have a greater Surface area than the ID.

My question: Can someone please explain to me how to go about finding the surface area the correct/better way?

The only insight that I can provide is that the Curve uses center of the stylus ball, rather than the contact points. So, you would probably need to find a way to offset that by 1/2 of your probe diameter
