Activity 5.5b CAD Model Features Part 2 Conclusion 1.          What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer. Revolve would be the most efficient because I could do cross section of the whole bat then revolve full. 2.          How does a 3D CAD solid model program display the progression of work involved in creating a model? The browser shows different parts of the object in question. Such as extrusion, sketches, revolve. 1.          If a mistake is made, how does the user make a correction without using the undo function? There are many ways, if it's some sketch error the user can delete and redraw. If dimensions such as fillet and lengths are wrong, numbers can be inputted again.

Activity 5.4 Calculating Properties of Solids Conclusion 1.          What is the difference between area and volume? Area only consist of two dimensions while volume consist of three dimensions. 2.          What is density? Density is the amount of mass in a certain volume. 3.What is a “physical” property? Give examples of physical properties Physical properties can include texture, color, length, and mass.
