Abstract

A computer method and apparatus for selecting and manipulating curvilinear shapes entered by a user is shown. The curvilinear shapes are represented within the computer using parameterized equations. The representation is reduced to maximal elements. The maximal elements are extended. Registration points of the extended maximal elements are then identified. Once the registration points and maximal elements are known, curvilinear shapes can be matched using those maximal elements and registration points. Therefore a user can create a sketch that looks like part of a drawing and the computer can find the corresponding section for the user and transform it.

         20 . A computer method comprising executing operations on a data processing device, the operations comprising:
 displaying a drawing to a user, including at least a curvilinear portion;   receiving at least one user command, responsive to the displaying, including a user created shape evoking the curvilinear portion;   identifying a candidate match to the user created shape within the drawing;   presenting to the user an indication of the candidate match in conjunction with the drawing.   
     
     
         21 . The method of  claim 20 , wherein the user command comprises a sketch. 
     
     
         22 . The method of  claim 20 , wherein the candidate match is an explicit shape from the drawing. 
     
     
         23 . The method of  claim 20 , wherein the candidate match is an implicit shape from the drawing. 
     
     
         24 . The method of  claim 20 , wherein identifying the candidate match comprises treating the curvilinear portion as a union of a plurality of shapes.

         31 . The method of  claim 26 , wherein the transformation comprises stretching. 
     
     
         32 . The method of  claim 26 , wherein the transformation comprises scaling. 
     
     
         33 . The method of  claim 26 , wherein the transformation comprises translating. 
     
     
         34 . A non-transitory machine readable medium embodying machine readable code, the code being adapted to cause a data processing device to perform operations, the operations comprising:
 displaying a drawing to a user, including at least a curvilinear portion;   receiving at least one user command, responsive to the displaying, including a user created shape evoking the curvilinear portion;   identifying a candidate match to the user created shape within the drawing;   presenting to the user an indication of the candidate match in conjunction with the drawing.   
     
     
         35 . The medium of  claim 34 , wherein the user command comprises a sketch. 
     
     
         36 . The medium of  claim 34 , wherein the candidate match is an explicit shape from the drawing. 
     
     
         37 . The medium of  claim 34 , wherein the candidate match is an implicit shape from the drawing. 
     
     
         38 . The medium of  claim 34 , wherein identifying the candidate match comprises treating the curvilinear portion as a union of a plurality of shapes. 
     
     
         39 . The medium of  claim 34 , wherein identifying the candidate match comprises treating the curvilinear portion as a difference among a plurality of shapes. 
     
     
         40 . The medium of  claim 34 , wherein the command includes a specification of a desired transformation related to the curvilinear portion. 
     
     
         41 . The medium of  claim 40 ,
