Solid creation and 3 D rotation in AutoCad
Project
The intent of this project is to facilitate the understanding and the application of geometry in relation to the design of forms and shapes.
AutoCad is the tool that allows the design of a part, and Geometry Sketchpad allows the analysis of shapes, area and perimeters.
Volumes also are written in the Geometry Sketchpad.
The part's intent can be evaluated prior to its design.
The use of the software leads to the interdisciplinary of geometry and computer aided design

Project's Assumptions:
The client wants that you to design a bottle (round in shape) for a new
cologne that he intends to market: Price and Quantity Table
The specifications state that the bottle contains 3.4 fluid ounces, and aesthetically reflects the test and style of the current market.
The bottle materials can be white or colored glass or other synthetic matter, as long as it reflects the product as very fine and exclusive cologne.
Day 1
Evaluate the problem. Search for a tool on the Internet to convert fluid ounces in to volumes, or use the conversion table below. Explain the concept of 2D objects when, rotated along one of its axis, create a solid and a volume.
Day 2
Geometry Sketchpad: Sample of figures, areas that best represent the area and volume desired. The different geometry shapes and their aesthetically feasible forms can be analyzed and saved. All the different results can be copied and pasted onto a spreadsheet.
Day 3
From the acquired information different shapes can be created in AutoCad.
The shape has to be in an enclosed shape; area and perimeter can be analyzed, copied and stretched with the use of AutoCad commands.
Modifying and making the necessary adjustments, to justify the desired shape of the bottle, an exterior shape can be created around the volume that was obtained from the rotation of the enclosed object.
Day 4
Rotate the shapes created along an axis. Analyze volumes of the two solids. Information can be saved and printed or can be pasted into a spreadsheet.
Java File to manipulate area & volume of a figure
Using the Boolean operations of adding or subtracting AutoCad allow to subtract one solid (volume) from another.
Analyze the new solid and volume created by subtracting of the two solids.
The solid can be cut (section to see the interior of it).
The cutting plane can be perpendicular or to any angle and degrees desired.
Day 5
AutoCad drawing can be saved as a .SAT file. This file format can be opened using a freeware on the Internet:
Acis viewer. (Make sure to download this prior to attempting to view .Sat files), that allows the solid to be animated, revolved, and spun.
The AutoCad drawing can also be saved as a *.dwf file. File can be loaded on a freeware account on the Internet:
Viewcad.
