Abstract
This study proposes a technique to associate design intentions with each figure in drawing. The technique will contribute to information sharing among designers and manufactures reducing in design errors by misunderstanding of design intentions. A CAD is developed by applying the technique with the functionality to draw basic figure elements necessary for mechanical designs. The applicability of the CAD is subjectively evaluated by five evaluators comparing with the ordinal method of describing design intentions in documents through the task to understand an improved design of a simple robot arm. The CAD has higher evaluation points in the viewpoints of understandability of figure change history and efficiency. It also has equivalent points in the viewpoints of understandability of change points and understandability of relation with other changes.
