DEVICE FOR CONSTRUCTING THREE-DIMENSIONAL MODEL FOR DESIGN AND CONSTRUCTION OF BRIDGE

摘要

PROBLEM TO BE SOLVED: To simply prepare a design drawing of bridge and parts information for the construction of bridge. ;SOLUTION: Design drawing 4 and parts information for the construction of a bridge are prepared from bridge completion system linear data 1 and construction system linear data 2 adding a camber value 22 to the data 1 by the use of an arithmetic method 3a common to plural bridge sorts and an individual arithmetic method 3b different for every bridge sort. A reference line for the data 2 can easily be obtained by adding the camber value 22 to a reference line for a completion system three-dimensional model based upon the data 1. Consequently, the parts information for the construction can be prepared without preparing the design drawing 4.;COPYRIGHT: (C)1997,JPO
