Automated Finish Material Mapping for 3D CAD Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CAD systems require manual and time-consuming processes to accurately display complex 3D models with finish materials, which are prone to errors due to the lack of direct mapping between CAD model data and finish material data, often managed in separate spreadsheets and image-based formats.
Innovation Solution
Automated methods and systems that map finish material data to CAD model data by reformating spreadsheet data into a structured database, integrating material information from third-party sources, and displaying CAD models with proper finish materials, while identifying and highlighting errors for user correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual processes are used to map finish material data to CAD model data, then accuracy can be maintained through human review, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The system performs automated self-mapping of finish material data to CAD model data by reformating spreadsheet data into structured databases and automatically associating materials with parts based on item numbers, eliminating the need for manual intervention while maintaining accuracy through systematic data processing
Solution Approach 2:
The manual mechanical process of reviewing and mapping materials is replaced with an automated computational system that uses database queries and algorithmic matching to associate finish materials with CAD parts, dramatically reducing time while preserving accuracy through consistent rule-based processing
2Adaptability or versatility
If separate spreadsheets and image-based formats are used to manage finish material data, then flexibility in data management is maintained, but direct mapping between CAD model data and finish material data becomes difficult and error-prone
Solution Approach 1:
The patent introduces structured databases as an intermediary layer between the existing spreadsheet/image-based finish material data and the CAD model data. This intermediary reformats and standardizes the data into a reliable format that enables accurate automated mapping while preserving the flexibility of the original data sources
Solution Approach 2:
The system changes the parameter format of finish material data by converting unstructured spreadsheet and image-based data into structured database formats with standardized fields and relationships, enabling reliable automated processing while maintaining the adaptability of the original data through configurable data import processes
3Productivity
If automated methods are used to display CAD models with finish materials, then productivity and speed are improved, but the complexity of the system increases
Solution Approach 1:
The patent segments the complex task of displaying CAD models with finish materials into distinct modular components: data import module, database reformatting module, material-CAD association module, and rendering module. This segmentation reduces system complexity by making each component independent and manageable while enabling high-speed automated processing
Data Source
AI summary
Methods and systems display a computer-aided design (CAD) model with finish material specificity. An example embodiment begins by defining a CAD model in memory where the CAD model represents a real world physical object and the CAD model comprises a plurality of parts. Next, the example embodiment obtains spreadsheet data that relates material finishes with item numbers, and then, reformats the obtained spreadsheet data into a structured database. In turn, indications associating the parts or model elements of the CAD model with the item numbers are received and the CAD model is automatically displayed with the parts having the material finishes based on the structured database and the received indications of item numbers associated with the parts of the CAD model.
