The waterfall model is a sequential design process, often used in S/W development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance. (Wikipedia: Waterfall model)

1st Proposal Presentation Goal• Enable user to customize sizing of a product based

on the given template before printing it by 3D printer.

• Connecting a user interface based on HTML, export the data to CAD s/w, and enable it to produce relevant STEP and STL file for 3D printing purpose

• Enable user to view the design in 3D preview

• Implementing STEP built database

Product:• Simple table lamp (current

target)Our Focus:• Customizable

sizing parameter: height, width, diameter

• Lamp cover design personalization:a. Colorb. Picture

• Provide 3D Preview after the customization

Revised Goal• Web based implementation• Parameter input using HTML5 & ASP, saved in internal server in .txt format• Input file is parsed and fed to the CAD s/w by using related API• Drawing modification in server using API of CAD system and saving for downloading purpose of

users• Save the model in various format (.stl, .stp, .x3d)

Revised Goals in Nutshell

• Input using HTML• Saved in the server using .txt format

Parameter Input

Achieved objective: The Web development

Additional goal:Embedding a 3D

viewer

Deployed into an internal server

Integrating HTML5, ASP,

and SQL

Saving user input in .txt format

readable by the CAD s/w API into a remote server

Discussion: Choice of CAD Systems

CAD with simpler API Easy embedding options Cloud CAD system

Possible CAD system options• Google sketchup• Autodesk Inventor

Additional Goals• Embedding STEP or STL viewer on the web for visualization• Adding more customizable product
