Reverse engineering support apparatus

A reverse engineering support apparatus that converts mesh data, obtained by measuring a shape of a workpiece, into CAD data and outputs the CAD data, the reverse engineering support apparatus comprising:

• a data acquisition unit that acquires the mesh data of the workpiece;
• an extraction unit that extracts a plurality of geometric elements from the mesh data of the workpiece acquired by the data acquisition unit;
• a reception unit that receives selection of one geometric element from among the plurality of geometric elements extracted by the extraction unit and receives selection of a type of a logical operation of the one geometric element;
• a registration unit configured to be capable of registering, in a synthesis processing table, a plurality of records in which types of logical operations received by the reception unit are associated with geometric elements received by the reception unit, respectively;
• a computing unit that executes a logical operation of a geometric element based on a type of the logical operation associated with each of the records for each of the records, included in the synthesis processing table and registered by the registration unit, to create a synthetic element;
• and
• a display control unit that causes a display unit to display the synthetic element created by the computing unit.
