ABSTRACT:
In a product design system having a computer and an interactive program stored in the computer for aiding the engineer to design a product and including product design process for allowing the engineer to design a product model and mold design process to design a mold for producing the product based on the designed product model, the program is rewritten such that a basic element that constitutes the product model is constituted, a fillet is applied on the constructed basic element, and it is judging whether a release draft formed on the constructed basic element with the applied fillet is sufficient for releasing the product from the mold to be designed on the mold design process. With this, since the product model is assigned with the fillet in the initial design stage of the product design process, the engineer can continue designing while confirming or verifying the function of the element based on the product model to which fillet has been applied. Further, this can make the release draft correction operations easier than that in the prior art.
