Part-Centric Coordinate Indicators for CAD Assembly Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAD data manipulation tools lack intuitive methods for users to efficiently translate and rotate complex assembly parts, relying on global coordinate systems that require numerous steps and are not user-friendly.
Innovation Solution
A computer system and method that displays indicators for element coordinate axes associated with selected parts, allowing users to perform translations and rotations directly on a part-centric coordinate system, reducing the complexity of manipulation and facilitating easier interaction with CAD data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If global coordinate systems are used for manipulating CAD parts, then manipulation can be performed, but the number of steps increases and user-friendliness deteriorates
Solution Approach 1:
The patent divides the coordinate system manipulation into local segments by introducing element coordinate axes specific to each selected part, rather than using a single global coordinate system. This segmentation allows users to manipulate each part independently in its own local coordinate context, reducing the complexity and number of steps required for manipulation.
Solution Approach 2:
The patent introduces visual indicators representing element coordinate axes as an intermediary between the user and the CAD part manipulation. These indicators serve as a mediator that provides intuitive visual feedback and control mechanisms, making the manipulation process more user-friendly and reducing the cognitive load on users.
2Productivity
If part-centric controls are implemented, then manipulation efficiency improves, but system complexity increases
Solution Approach 1:
The patent creates visual copies or representations of the element coordinate axes as indicators displayed on the screen. These visual copies provide the necessary control information without requiring complex underlying system changes, allowing efficient user interaction while maintaining system integrity.
Solution Approach 2:
The patent changes the parameter of coordinate system reference from global to local (element-specific) by dynamically adjusting which coordinate axes are displayed and used for manipulation based on the selected part. This parameter change enables part-centric controls without fundamentally altering the entire system architecture.

AI summary
Manipulation of a view of a selected part of an assembly is facilitated by the display of indicators for element coordinate axes associated with the selected part that form controls for effecting at least one of a translation and a rotation of the selected part of the assembly.
