For the first model, I created the sketch with the circle hole in the middle. I then created all of the vertical and horizontal lines, leaving the tangent curves for last. For the second model, I did a cut extrude through the mid plane, and cut off the edges using the chamfer tool. For the last model, I offset the front plane entities by 2mm, then offset that from the surface of the extruded cut by 2.5.Mass = 18252.46 gramsVolume = 2050838.72 cubic millimetersSurface area = 210429.73 square millimeters
