Abstract: A graphic form correction apparatus and method for a CAD system wherein a display position of a dimension-relating symbol such as a dimension line, an extension line or a dimension value entered on a two-dimensional graphic form is automatically corrected in response to a correction of the two-dimensional graphic form. The graphic form correction apparatus includes an additional symbol arrangement section for arranging an additional symbol such as a finish symbol or a surface roughness in the proximity of the dimension-relating symbol, and an additional symbol position storage section for storing a display position of the additional symbol and a display position of the dimension-relating symbol in a coordinated relationship.
