Abstract: A system and method for taking-off material details using a two-dimensional CAD interface for estimating a bill of materials and automatically creating a material take-off list for items in a two or three-dimensional design drawing, without manual work. The taken-off list information is provided on-line upon receiving an order for an information provision service through a communication network, such as the internet. The system is applicable, for example, in architecture, civil engineering, machinery, and facilities. The system comprises: a project information containing unit for containing project information including position data, design specifications, and shape data for a variety of design items; a material/cost containing unit for containing material information and cost information for building elements included in a CAD drawing; and a bill-of-material take-off processing unit for creating a material take-off list and the associated cost.

Abstract: A method for providing construction information service about a structure is provided. The method comprises design data inputting step that inputs design data that comprises two-dimensional drawings that illustrate construction elements of the structure, design data analyzing step that comprises analyzing the drawings to extract geometrical data of the construction elements and reading engineering data of the construction elements, reference data retrieving step that retrieves reference data related to the construction elements from a database, information producing step that produces construction information from the geometrical data and the engineering data analyzed from the drawings and the reference data retrieved from a database, and information outputting step that outputs the construction information.

Abstract: The present invention provides to a system and method for the take-off of the materials using a two-dimensional CAD interface, and more particularly, to a system and method for estimating a bill of materials using a two-dimensional CAD interface which automatically take-off a full bill of material and cost information for items stated in a two or three-dimensional design drawing without a manual work or transformation, and which provides the taken-off information in on-line by receiving an order for an information provision service for a two-dimensional CAD drawing through a communication network, such as the internet, and automatically executing the information about bill-of-material estimating, details, and cost management.
