Drawing Object Inference System for CAD Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer-aided design (CAD) systems lack efficient methods for recognizing and beautifying freehand drawings of objects, particularly in terms of matching the size and shape of newly drawn objects with existing objects on the workspace, leading to inconsistencies in graphical user interfaces.
Innovation Solution
A system and method utilizing a processor to determine the type and size of newly drawn objects and replace them with smoothly drawn versions that match existing objects within predetermined tolerances, ensuring consistency and aesthetics in CAD drawings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If freehand drawing input is accepted for object creation, then ease of operation is improved, but manufacturing precision deteriorates due to size and shape inconsistencies
Solution Approach 1:
The system creates a replacement object that copies the characteristics of an existing object on the workspace, replacing the imperfect freehand drawing with a precise version that matches the existing object's size and shape properties
Solution Approach 2:
The system modifies the parameters (size, shape) of the newly drawn object to match the parameters of the existing object within predetermined tolerances, transforming the inconsistent freehand drawing into a consistent geometric object
2Adaptability or versatility
If multiple object sizes and shapes are allowed, then adaptability is improved, but visual consistency deteriorates due to aesthetic inconsistencies
Solution Approach 1:
The system copies the geometric characteristics of existing objects to replace newly drawn objects, ensuring that all objects of the same type maintain consistent visual appearance while allowing different object types to coexist

AI summary
A system (100) having a processor (102) is provided that visually manipulates objects on a touch screen responsive to inputs (116) through the touch screen. Based at least in part on data representative of type and size for a plurality of prior objects (112) displayed through a display device (108), the processor may determine that at least one input through the input device (110) corresponds to a further object (122) having a determined type corresponding to at least one of the prior objects and having a size within predetermined tolerances of corresponding to the at least one of the prior objects. Also the processor may cause responsive thereto the display device to display a replacement object (126) in place of the further object having a size and shape corresponding to the at least one prior object.
