Dynamic BIM Cross-Section Views with Gridlines and Dimensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software tools for rendering three-dimensional views of construction projects do not provide all the information available in two-dimensional technical drawings, such as dimensioning information, and often lack gridlines that are crucial for precise construction measurements, leading to time-consuming manual calculations and potential errors.
Innovation Solution
A software application that plots gridlines within two-dimensional views based on three-dimensional BIM files and provides dynamic dimensioning information, allowing for efficient location of physical elements by converting gridline information from a universal coordinate system to a project-specific system and updating dimensioning information based on user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional views are used to visualize construction projects, then the overview completeness is improved, but the information completeness (dimensioning information, gridlines) deteriorates
Solution Approach 1:
The patent overlays two-dimensional gridlines and dimensioning information from technical drawings onto three-dimensional rendered views. This creates a hybrid visualization that maintains the spatial context of 3D while incorporating the precise measurement data from 2D drawings, allowing users to see both the overall structure and specific dimensions simultaneously without switching between different view types
2Measurement precision
If two-dimensional technical drawings are used to provide dimensioning information, then the measurement precision is improved, but the productivity deteriorates due to multiple drawings required
Solution Approach 1:
The patent combines multiple two-dimensional technical drawings into a single integrated three-dimensional view by overlaying gridlines and dimensioning information from multiple drawing sources onto one 3D rendered model. This consolidation allows reviewers to access information that would normally require multiple separate drawings without having to switch between them, improving review efficiency while maintaining measurement precision
3Measurement precision
If gridlines are added to two-dimensional views from three-dimensional files, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent uses the existing gridline system from two-dimensional technical drawings as an intermediary to transfer precise measurement information onto three-dimensional views. Rather than creating a new complex gridline generation system, the software extracts gridline data from standard technical drawings and maps them to the 3D model coordinates, leveraging existing infrastructure to achieve precision without proportionally increasing complexity

AI summary
An example computing system is configured to (i) receive a request to generate a cross-sectional view of a three-dimensional drawing file, where the cross-sectional view is based on a location of a cross-section line within the three-dimensional drawing file and includes an intersection of two meshes within the three-dimensional drawing file; (ii) generate the cross-sectional view of the three-dimensional drawing file; (iii) add, to the generated cross-sectional view, dimensioning information involving at least one of the two meshes; (iv) generate one or more controls for adjusting a location of the cross-section line within the three-dimensional drawing file; and (v) based on an input indicating a selection of the one or more controls, adjust the location of the cross-section line within the three-dimensional drawing file, update the cross-sectional view based on the adjusted location of the cross-section line, and update the dimensioning information to correspond to the updated cross-sectional view.
