Method and system for manipulating construction blueprint documents with hypermedia hotspot reference links from a first construction document to a related secondary construction document

摘要

A system (10) allows the storing of construction drawings or blueprints in a plurality of computer files (32). The system (10) allows automatic determinations of lengths, areas and count of dimensions displayed in drawings. The measured dimensions are provided in terms of real world or full scale quantities. A scale between the full scale quantities and computer displayed dimensions is determined for each file (32) to allow subsequent measurements scaled in terms of the original blueprint designated dimensions. The dimensions are identified with particular product items so that a quantity of items and costs thereof may be automatically determined and reported.
