Conventionally, in the process for inspecting a molded product, a measurement point indicating a portion to be measured is defined by using attribution information, such as a tolerance difference, and a measurement program is created, or a manual measurement instrument is employed to conduct the measurement. According to the invention, provided is an information processing apparatus supporting general measurement operations, including those for manual measurements, by using attribution information, such as a dimension and a dimensional tolerance, that is added to a CAD model generated by a CAD apparatus.
