Plate

Mass = 84184.05 grams Volume = 31179276.94 cubic millimeters Surface area = 1916449.49 square millimeters For this model, I started by creating a sketch on the right plane. Using the line tool I drew the desired drawing, then using the revolved boss/base tool made the model 3D. I then switched to the front plane and created a new sketch. After drawing the desired shapes I used the extruded cut tool to make the detail hallow.
