System for converting a rough sketch to a finished drawing

摘要: By means of a suitable data entry device such as an electronic digitizing tablet or graph board, items respectively defining the original configuration roughly sketched object and desired final proportions thereof are entered into stored table called "pointing sequence list" (PSL), which is capable storing all information required to define both form object. Initially PSL contains positional entries representing coordinates definitive points on dimensional specifying have in its delineation, arranged order corresponding predefined pointing followed by operator when he enters necessary graphic system. The initial subsequently converted new rectifying procedure modifies previously where effect horizontal vertical alinements supposed be located common axially directed lines. Whenever coordinate modified axial alinement (or some instances joinder) between two more during rectification process, respective corresponds provided with "pointer" location specifies referenced coordinate, thereby establishing equivalence these entries. linkages among equivalent preserved subsequent processing operations performed upon entries, so that change one member each set affects other members thereof. then further accordance specified various ultimately positions rectified proportioned version rough sketch, enabling finished drawing representation produced from
