AI Technical Summary

Technical Problem

Existing technologies for generating pipe isometric drawings lack interactivity on the browser side, with overlapping annotation information and difficulty in preserving the semantic attributes of components, resulting in low efficiency for construction personnel to obtain information. Furthermore, traditional drawing generation technologies cannot solve the problems of display distortion of long and short pipe sections and exceeding drawing size limits.

Method used

A computer system based on SVG vector drawing is used. A logical directed graph is constructed through a data parsing module, and an isometric drawing skeleton is generated using a projection transformation module. By combining a visual compression module and an intelligent layout module, nonlinear visual compression and automatic obstacle avoidance layout are achieved, generating highly interactive SVG format pipeline isometric drawings.

Benefits of technology

It enables efficient information retrieval and 3D visual effects on the browser side, solves the problems of display distortion of long and short pipe sections and map size exceeding limits, and improves the efficiency of information acquisition for construction and operation and maintenance.

Abstract

This invention discloses a computer system for designing isometric pipe drawings based on SVG vector graphics, belonging to the field of industrial engineering computer-aided design technology. The system includes: a data parsing module for constructing a logical directed graph of the pipeline; a projection transformation module for mapping three-dimensional coordinates to a standard isometric viewpoint; a visual compression module for balancing the visual length of long and short pipe segments using a nonlinear logarithmic algorithm; a vector rendering module for instantiating components and weld elements based on SVG templates and binding physical attributes; and an intelligent layout module for detecting and eliminating annotation occlusion using a quadtree. This invention, through lightweight SVG technology and intelligent layout algorithms, achieves automated generation, visual optimization, and web-based interactive querying of isometric pipe drawings, effectively solving the problems of disproportionate scale and static information in traditional drawings.
