Position Fine Tuning in Computer Aided Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-aided modeling systems face challenges in precisely fine-tuning the position of objects within a model without altering their creation points, which is essential for detailed drawings and representations.
Innovation Solution
A graphic user interface-based position tool with rotation and offset tools allows users to adjust the position of objects within a model independently of their creation points, using a rotation tool to rotate around the creation axis and an offset tool to move the object on a perpendicular plane, facilitating precise positioning through user input.

Engineering Contradiction Analysis
1Ease of operation
If position fine tuning is performed by moving objects from their creation points, then position adjustment capability is improved, but the original creation points are altered which affects model accuracy
Solution Approach 1:
The position adjustment operation is segmented into two independent components: rotation around the creation axis and offset movement on the perpendicular plane. This allows the object to be rotated to the correct orientation and then offset to the correct position without moving the creation point, thus maintaining model accuracy while enabling position fine-tuning
Solution Approach 2:
An intermediary coordinate system is introduced with origin at the creation point and axes aligned with the object's local coordinates. This intermediary system allows position adjustments to be expressed as rotation and offset operations rather than direct movement, preserving the creation point while achieving the desired position change
2Productivity
If traditional position adjustment methods are used, then simple operation is maintained, but processing resources are wasted due to errors in position fine-tuning
Solution Approach 1:
The system provides visual feedback by displaying the object in its new position after rotation and offset operations, allowing users to verify position accuracy immediately. This feedback mechanism reduces errors and rework, improving both reliability and productivity
Solution Approach 2:
The creation point is established as the origin of a local coordinate system before position adjustment operations. This preliminary setup enables subsequent rotation and offset operations to be performed systematically, reducing errors and improving position accuracy without requiring additional processing resources

AI summary
A position fine tuning of an object without movement of creation points of the object is facilitated with a position tool having a graphic position tool displayed on a display. The graphic position tool may comprise a rotation tool, dragging of which causes the object to rotate accordingly around its creation axis, and/or an offset tool, either a clickable one or a draggable one, with which the object's position on an offset plane can be changed. A clickable offset tool may comprise buttons clicking of which causes the object to move a predetermined offset value(s) to a direction defined by the button.
