Abstract: [Problem] To provide a design assist device that handles a component, wherein it is possible to prevent an unnecessary model replacement process for an altered component. [Solution] When an indication for altering a design component is made, determination is made as to whether or not the indication of alteration falls under the category of an indication of specific alteration and, when determined as being an indication of specific alteration (Yes in STEP 1), an alteration corresponding to the indication of specific alteration is carried out without performing a model replacement process, or when determined as not being an indication of specific alteration (No in STEP 1), a model replacement process is carried out (STEP 9). The above process makes it possible to prevent an unnecessary model replacement process from being carried out, so that association between each component after alteration is maintained and the time and effort of a designer can be reduced.
