Solution Overview
Problem
In computer-aided design (CAD) programs, users face the tedious and time-consuming task of replicating geometric features in multiple regions of a design, which can lead to errors and inefficiencies.
Innovation Solution
A computer-based method that enables users to create or select a geometric entity, predict its location and orientation in the design for a copy, and display a visual representation of the copy as a suggestion, allowing users to easily replicate geometric features in similar regions.

1Productivity
If users manually create geometries in each region, then design flexibility is maintained, but the task becomes tedious and time-consuming
Solution Approach 1:
The system performs preliminary analysis of the design model to identify similar regions and predict optimal locations for geometry replication before the user completes the creation process. The predictive modeling algorithm analyzes geometric features, surrounding contexts, and design patterns to pre-determine where copies should be placed, reducing the user's manual workload and accelerating the design process.
Solution Approach 2:
The system creates copies of selected geometric entities and automatically positions them in predicted locations based on identified similar regions. This copying mechanism allows the geometry to be replicated across multiple regions without requiring manual re-creation, significantly improving productivity while maintaining design intent through intelligent placement algorithms.
2Reliability
If users manually replicate geometries, then control over placement is maintained, but errors and inefficiencies increase
Solution Approach 1:
The system provides feedback to the user by displaying predicted locations and orientations of copied geometries before final placement. This feedback mechanism allows users to review and verify the automated predictions, correcting any errors while maintaining high accuracy. The feedback loop ensures that time is not lost to incorrect placements, as the system guides users through the process with intelligent suggestions.
Solution Approach 2:
The patent replaces the mechanical manual process of measuring, marking, and positioning geometries with an automated computational system. The predictive modeling algorithm substitutes human manual operations with algorithmic analysis of design models, identifying similar regions and calculating optimal positions automatically, thereby eliminating time-consuming manual tasks while maintaining precision through computational accuracy.
3Productivity
If the system predicts copy locations automatically, then productivity increases, but the system complexity increases
Solution Approach 1:
The predictive modeling system is segmented into distinct functional modules: geometric feature extraction, similar region identification, location prediction, and visualization. This segmentation allows each module to perform a specific function independently, making the overall complex system more manageable and easier to implement. The modular architecture processes information in stages, from raw geometric data to final predicted locations, reducing the cognitive load on any single component.

AI summary
A computer-based method includes enabling a user to create or select a geometric entity in a design in a computer-aided design program, predicting a location and orientation in the design for a copy of the geometric entity, and displaying, as a suggestion to the user, a visual representation of the copy of the geometric entity in the predicted location and orientation in the design.
