How to do three-dimensional inspection of eggs with a ruler

1, the key is dimension. The easiest way: first find an egg with the same shape as you want to draw, cook it, and then cut it in half along the' long axis' direction. Take a copy, buckle its plane on the paper and draw the outline of the main view. Then measure the arc radius of the big head and the small head, the distance between the centers and the radius of the connecting arc on the drawing to formally draw the arc connection. Measure the roughest radial dimension and draw a circle to show the left view. (the top view is omitted, and the left view can also be omitted) 2. When drawing formally, draw the front picture of the egg with the measured size. Then divide the egg into several equal parts along the length direction, and draw several removal sections (indicating the change of different circle diameters of the egg at different positions) respectively. Finally, just mark the size.
