Work support apparatus and work support method

A work support apparatus comprising:

• a line and point detection unit configured to acquire drawing data in which a circuit indicating a connection relationship between devices is described by a character, a line, and a point, and to detect the line and point based on the drawing data;
• a drawing sign detection unit configured to detect a drawing sign constituting the circuit;
• a wiring detection unit configured to detect a wiring connecting the drawing signs based on information on the line and point;
• a character detection unit configured to detect the character;
• a circuit connection information generation unit configured to generate circuit connection information by extracting information on contact of the drawing sign with the wiring on the drawing data based on coordinate data on the drawing sign and the wiring included in the same page of the drawing data;
• and
• a terminal component detection unit configured to detect, as a terminal component, a wiring or first drawing sign that is not connected to a second drawing sign at least at one end based on the circuit connection information generated by the circuit connection information generation unit, since the circuit connection information in the same page and over pages of the drawing data is generated.
