A method for generating a three-dimensional sheet-metal model utilizing a feature for generating a general solid model without a sheet-metal attribution is provided. The method includes the steps of estimating a thickness of a sheet-metal from a cross section designated by a user, representing a bent portion of the sheet-metal by rotating a cross section designated by the user around a set axis in accordance with a bending direction designated by the user and by sweeping the rotated cross section by a length designated by the user, representing an abutting portion by sweeping a cross section designated by the user by a length designated by the user, and realizing sheet division by a sweep slit that is formed by sweeping a tiny cross section including a division line designated by the user on a plane designated by the user.
