Dynamic Bend Point Snapping for CAD Right Angle Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CAD methods for shaping linear segments at right angles are slow and cumbersome, often requiring grid snapping or constrain angle tools that limit user efficiency.
Innovation Solution
A dynamic bend point selection method that determines primary and secondary snap points based on predetermined regions and displays reference lines to facilitate quick formation of right angles without relying on the grid, allowing dynamic snapping to create new linear segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If grid snapping or constrain angle tools are used to shape linear segments at right angles, then the linear segments can be properly aligned, but the operation becomes slow and cumbersome
Solution Approach 1:
The patent applies dynamics by making the bend point dynamic rather than fixed. The bend point automatically adjusts its position based on cursor movement and dynamically determines snap points, allowing the system to adapt to user intent in real-time without requiring manual grid alignment or constraint tool configuration
Solution Approach 2:
The system performs self-service by automatically determining snap points and forming right angles without user intervention. The dynamic bend point automatically snaps to appropriate locations and creates perpendicular segments, eliminating the need for users to manually use grid snapping or constrain angle tools
2Manufacturing precision
If grid snapping is used to draw linear segments at right angles, then proper alignment is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the complexity of grid snapping and constraint tools by removing the need for these separate mechanisms. The dynamic bend point inherently provides right angle formation without requiring grid systems or angle constraint tools, simplifying the overall CAD interface while maintaining precision
Solution Approach 2:
The dynamic bend point serves multiple functions: it positions segments, creates right angles, and determines snap points all in one operation. This multi-functional approach replaces the need for separate grid snapping tools and angle constraint tools, reducing device complexity while maintaining manufacturing precision
3Manufacturing precision
If conventional linear segment shaping methods are used, then right angles can be formed, but user efficiency is reduced due to slow and cumbersome operations
Solution Approach 1:
The system performs preliminary action by pre-determining snap points based on the dynamic bend point location before the user finalizes the segment creation. This allows the system to prepare alignment options in advance, making the actual segment formation quick and efficient while maintaining precision

AI summary
A method and apparatus for shaping a linear segment is disclosed. The method comprises the steps of selecting a dynamic bend point, determining a primary snap point based on the location of the dynamic bend point in one of four predetermined regions and snapping the dynamic bend point to the primary snap point. A secondary snap point is also determined and the dynamic bend point is snapped either to the primary snap point or to the secondary snap point, depending on the location of the dynamic bend point inside or outside a predetermined secondary snap region.
