activity 5.5b
description
Two dimensional sketches are nice, but parts have three-dimensional (3D) qualities that sketches can only imitate and communicate in an abstract manner. CAD 3D solid modeling programs can bridge the gap between 2D representations and 3D artifacts by providing an electronic representation of an object that can be moved and rotated so that all aspects of the object can be viewed.
A sketch in a 3D Computer Aided Design (CAD) solid modeling program serves as the foundation for a three-dimensional feature. Some three-dimensional features require a sketch from which the 3D form is created. Other features do not require a sketch, but instead require a three-dimensional form.
In this activity you will learn about and use additional tools and features within a CAD program to enhance your knowledge of the capabilities of the program and improve your skill in producing 3D solid models.

conclusion
What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer.
Loft-- if find it easier to create and just use that.
How does a 3D CAD solid model program display the progression of work involved in creating a model?
You see what parts you have done, basically the outline of the creation.
If a mistake is made, how does the user make a correction without using the undo function?
You can cut lines with the trim key.
