Home Design: CAD Roof Design Tool

I’m looking for a coder to develop software that designs pitched roofs for homes. This software needs to create the wire frame outline of the roof based on user specified length and width inputs as well as roof pitch desired. In addition, the planes of the roof need to accept pattern fills with shingle patterns and basic plane shading. Here are the specifics: User inputs perimeter roof desired in a conventional cad line fashion. Each plane of the roof is linked to an excel style database. The database is then populated with the pitch desired, hip or gable desired and base height of roof plane relative to other roof planes. Database then drives roof design and auto draws the roof for inspection. The database must display the length of all ridges, hips and valleys as well as overall roof heights. Database must be printable. Roof elevations and floorplan must also be printable. Printing must be allowable at 1/8, ¼, and ½ scale. Title block capability must be part of the printing and sheet layout process. Ability to customize the title block is important including the use of builders logo. User needs to be able to interactively drag elements of the drawn roof plane to fix design peculiarities… the database needs to auto-reflect these changes. User needs the ability to also click on a roof plane to display the attributes of that plane and then revise attributes as desired to change the roof design. Database also needs to reflect the correlation between base roof heights and heal height of roof truss. I am an experienced home designer, but not a programmer. I can help you technical roof questions, but you must possess at least a fundamental knowledge of home roof geometry. Check out the web site at [login to view URL] for typical home roof designs. Selected coder must sign NDA. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
