Linking 3D Design Files to 2D Documents via Coded Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current disconnect between three-dimensional (3D) design models and two-dimensional (2D) design documents in the AEC industry leads to inefficiencies during design reviews, where manual referencing is required to cross-reference between these disparate information sources.
Innovation Solution
A computer-implemented method and system that links a 2D design image to a 3D design model by converting the 3D model into a coded 2D design image, assigning unique identifiers to design elements, and aligning the 2D and coded 2D images to enable seamless identification of design elements based on user selections in the 2D image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual referencing is used to cross-reference between 2D design documents and 3D design models, then the disconnect between 2D and 3D information sources is maintained, but the ease of operation and efficiency during design reviews deteriorates
Solution Approach 1:
The patent merges the 2D design document and 3D design model into a single integrated system where elements in both representations share common identifiers and properties. This allows users to access information from either representation without manual cross-referencing, directly resolving the contradiction by improving ease of operation while reducing time loss through automated linkage between 2D and 3D views.
Solution Approach 2:
The patent introduces an intermediary data structure that acts as a mediator between 2D design documents and 3D design models. This intermediary layer maintains unique identifiers and property mappings that enable automatic cross-referencing, allowing users to navigate between 2D and 3D representations efficiently without manual intervention.
2Reliability
If 3D design models are converted to coded 2D design images with unique identifiers, then the linkage between 2D and 3D information is improved, but the device complexity increases
Solution Approach 1:
The patent segments the design data into distinct but linked components: 2D design documents with visual representations and 3D design models with geometric data, connected through shared unique identifiers. This segmentation allows each component to maintain its structural integrity while enabling reliable linkage, resolving the contradiction by improving reliability through structured data organization without excessive complexity.
Solution Approach 2:
The patent applies parameter changes by transforming 3D model data into coded 2D image representations with associated unique identifiers and property mappings. This transformation enables reliable linkage between 2D and 3D representations by changing the data parameters into a compatible format that maintains information integrity while facilitating cross-referencing.
