I work with Aluminum extrusions and we need to know the exterior perimeter and full perimeter. I used the measure tool to determine area and perimeter but, I also need the perimeter inside a hollow and the total perimeter. Any suggestions??

Thanks,

Adam

that number reported should be the inside loop + the outside loop. if you want just one of the loops, clear your selection and then right click on one of the edges,and choose "select loop". you may need to click onthe yellow arrow to flip to the other loop that that edge is a part of.
