Patent ID: 6864885

Claim:
A graphic form correction apparatus for a CAD system wherein a display position of a dimension-relating symbol in a coordinate relationship to a line segment being entered on a two-dimensional graphic form is automatically corrected and creates a corrected display position in response to a two-dimensional corrected graphic form, said graphic from correction apparatus comprising: means for arranging an additional symbol separate from and in the proximity of the dimension-relating symbol, wherein said additional symbol is not a dimension-relating symbol; means for storing both the display position of the additional symbol and the display position of the dimension-relating symbol in the coordinate relationship with the line segment; means for correcting the display position of the additional symbol based on the corrected display position of the dimension-relating symbol after the the display position of the dimenasion-relating symbol being corrected in response to an operation of an operator; means for detecting an overlap of the additional symbol after the corrected display position is created with another additional symbol and/or the dimension-relating symbol; wherein, after the overlap is detected, the means for correcting the display position of the additional symbol corrects the display position of the additional symbol with respect to both the dimension-relating symbol and the another additional symbol.
