I have a view in section and would like to calculate the area delimited by a closed arbitrary perimeter: as from the image I would like to calculate the area of the perimeter of the blue nets. Thank you.
I tried with prorieta section, but it doesn't work, it takes the whole section, there is no possibility to take one area, even after creating a closed sketch on the desired area
It turned out, creating a sketch on the sez. in scale 1:1 , I made copy and paste on a sketch of a part file, I did an extrusion and then in the end I am to make "measure on the extrusion face. But I finally got what I wanted.
