The invention discloses a modeling method for the rapid generation of pilot holes in a skin part. The method comprises the following steps of (1) selecting the coordinates of the central points of hole positions in a model structure tree; (2) selecting the plane of to-be-opened holes in a model geometry, and selecting the input aperture of a user interface; (3) selecting the geometry information of all to-be-opened holes in the model structure tree, and opening all to-be-opened holes at one time. According to the technical scheme of the invention, the coordinates of the central points of hole positions in the model structure tree are selected, and then the information including the plane of to-be-opened holes, the input aperture of the user interface, and the geometry information of all to-be-opened holes in the model structure tree, are selected. After that, all to-be-opened holes are opened at one time, so that the position accuracy of pilot holes is ensured. Meanwhile, the workload of designers is reduced and the working efficiency is improved.
