Lesson 7

Modeling and editing solids and surfaces. Primary solids. Boolean operations, Autocad (completion)

Exercise 1 - Sweep along helix

Create a box. Create a cilinder. Substract the cilinder from the box. Create a helix path. Create a circle. Sweep the circle along the path.

Substract Helix Sweep

Exercise 2 - Generating lines and mesh - Hyperboloid of revolution

Hyperbolic paraboloids

Create a rectangular shape with the opossing corners at different levels. Loft to create the surface. Write the code in Autolisp. Load the code in Autocad to create the same shape.
