AI Technical Summary

Technical Problem

Conventional technologies struggle to efficiently create design drawings that represent the location of symbols and piping routes in plant design, particularly in isometric projections, as they do not account for positional relationships and piping information beyond equipment connections.

Method used

A design support device utilizing a computer with a processor and memory to generate design condition information based on drawing and piping information, including orientation and attributes, and output modified drawings that depict symbol and piping positions and routes.

Benefits of technology

Enables efficient creation of design drawings that accurately represent symbol positions and piping routes, allowing for automated and instructed modifications based on user inputs, reducing processing load and enhancing drawing efficiency.

Abstract

This designing assistance device generates information that serves as a source of design condition information for creating a design drawing, on the basis of drawing information, which includes information about symbols constituting the design drawing and information about piping including at least orientation, and design information of piping, which is not shown in the drawing information, generates converted design condition information by converting the source information into a predetermined format, and outputs, as corrected drawing information, a design drawing that illustrates the symbols and the piping included in the generated design condition information.
