Hi! Sorry, I should’ve been more specific. Is there a way to find the perimeter of irregularly shaped cross-sectional areas (along centerline), especially if it is not a circle? Additionally, would there be a way to automate this process to find the perimeter along the centerline of a cross-sectional area, similar to an outputted table? I tired using the markup tool “closed curve” to get as close as I can to the perimeter. But I was wondering if there was a faster/automated way. Thank you!
