Unit 51: Basic Solid Modeling where solid modeling features are applied to REVOLVE and EXTRUDE commands.

Unit 52: Predefined Primitives that "permits to generate predefined solid primitives by specifying the necessary dimensions. Examples include boxes, cones, cylinders, and spheres.

Unit 53: Boolean Operation

"Much of AutoCad solid modeling is based on the principles of Boolean mathematics. AutoCad Boolean operations such as union, subtraction and intersection are used to create composite solids.

The practical aspect of the lesson plan is to engage the student with a "real" problem starting with initial calculations of areas and volumes requested by a prospective client who asks to design a product with certain requirements: amount of product to be stored and style reflecting exclusivity.

At the initial stage of the project, calculations, geometry and shapes are encouraged and welcomed. Teamwork may play a big part. Two or more students can work on one problem. One of the students may be stronger in math, another in design, another in marketing aspects, etc.

Completed projects may be evaluated and critiqued by other teams in the classroom. Projects may be corrected and improved by the original team.

This also could be a mid-term or final test completing the student's curriculum.
