Realization of two 3D solids with Autocad software: cones and cube with cut spheres.
Creating geometric figures inside 2 inverted cones (form an hourglass image)-circle, ellipse, parabola and hyperbola.
Main actions: form a cone, make a mirror to put one on top of another, create 4 layers (one for each geometric shape), create figures according to the main UCS.
Creating a cube with cut spheres and creating a video of 3D model.
Main actions: make a box, each surface will receive a sphere, combine geometric shapes and subtract what they have in common. Then make a shape on the ground that will serve as a rectangular base, draw them out and create an observer's view.
