The wall builder program is designed to produce a bill of materials for the home remodeler/builder. The user enters the company information for billing purposes on the bill of materials document. The user enter a project- customer name and address, etc. which is also used for the ship-to address on the bill of materials. The user enters walls by length and height; then adds windows and doors to the wall. As the entries are made, a window allows user to see all the entries made listed by wall number, updated with each new entry. When all entries have been made, the bill of materials is produced at the push of a button.
