Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software tools for rendering three-dimensional views of construction projects lack the ability to generate two-dimensional drawings that correspond to the three-dimensional view, fail to provide all available information, and do not offer a functional overview of the entire project, leading to limitations in dimensioning and navigation.
Innovation Solution
The software technology enables a computing system to generate two-dimensional technical drawings based on a three-dimensional model, including dimensioning information, and create functional insets by identifying intersecting meshes and compiling datasets to render accurate two-dimensional views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If three-dimensional views are used to present construction projects, then overview capability is improved, but dimensioning information completeness deteriorates
Solution Approach 1:
The system segments the presentation of construction project information by providing both three-dimensional views for overview and two-dimensional technical drawings for detailed dimensioning information. The two-dimensional drawings are generated from the three-dimensional model data, allowing users to access comprehensive dimensioning information without losing the benefits of three-dimensional visualization.
2Loss of information
If multiple two-dimensional drawings are used to represent multi-floor projects, then information completeness is improved, but device complexity increases
Solution Approach 1:
The system transitions from multiple two-dimensional drawings to a three-dimensional model that inherently contains all floor level information. By adding the vertical dimension to the model, the system can represent multi-floor projects in a single three-dimensional view while maintaining the ability to generate two-dimensional drawings for any specific floor level when needed.
3Measurement precision
If two-dimensional drawings are used for detailed information, then dimensioning precision is improved, but navigation efficiency deteriorates
Solution Approach 1:
The three-dimensional model serves multiple functions: it provides overall navigation and overview capability while also containing all the data needed to generate two-dimensional technical drawings with precise dimensioning information. This multi-functional approach eliminates the need to switch between separate two-dimensional drawings for navigation and detail viewing.

AI summary
The present disclosure is directed to a software tool that facilitates the presentation of a three-dimensional view of a construction project as well as the generation of various types of two-dimensional technical drawings based on this three-dimensional view. In one implementation, the software tool causes a computing device to engage in the following operations. The computing device may receive a user input identifying at least one first mesh and at least one second mesh, determine portions of each identified mesh that intersect with a two-dimensional plane, and generate a two-dimensional drawing including a display of relevant dimensioning information based on the determined portions.
